1 00:00:03,080 --> 00:00:07,240 Speaker 1: You have great taste in podcasts. This is deeply human 2 00:00:07,640 --> 00:00:11,360 Speaker 1: and I am your host, Tessa. Our topic of the 3 00:00:11,440 --> 00:00:15,200 Speaker 1: day is menopause. And before you run off thinking I'm 4 00:00:15,240 --> 00:00:17,400 Speaker 1: too young for this one or I'm too dude for this, 5 00:00:17,760 --> 00:00:20,800 Speaker 1: I can almost guarantee that you will be both surprised 6 00:00:20,840 --> 00:00:24,239 Speaker 1: and entertained, maybe even rendered a kinder son or daughter. 7 00:00:30,040 --> 00:00:33,400 Speaker 1: Menopause is actually a really rare condition in the animal world. 8 00:00:33,880 --> 00:00:35,800 Speaker 1: The only mammals will go through it are us and 9 00:00:35,880 --> 00:00:40,040 Speaker 1: some species of whales. Okay, sidebar for a quick story. 10 00:00:40,960 --> 00:00:43,440 Speaker 1: Many years ago, when I was twenty three, my doctor 11 00:00:43,479 --> 00:00:45,839 Speaker 1: found a tumor in my right ovary, and in a 12 00:00:45,880 --> 00:00:48,559 Speaker 1: blur of a few weeks, a surgery was scheduled. The 13 00:00:48,640 --> 00:00:50,960 Speaker 1: ovary was taken out, and I moved into my dad's 14 00:00:50,960 --> 00:00:54,480 Speaker 1: basement to recuperate. My doctor said I'd still be fertile. 15 00:00:54,880 --> 00:00:57,440 Speaker 1: My left ovary would essentially pull double shifts for the 16 00:00:57,440 --> 00:01:00,680 Speaker 1: next couple of decades, ovulating every month and releasing enough 17 00:01:00,720 --> 00:01:03,760 Speaker 1: hormones to keep my system balanced. But there was a 18 00:01:03,800 --> 00:01:07,160 Speaker 1: slight lag in my hormone production before my left ovary 19 00:01:07,319 --> 00:01:09,279 Speaker 1: realized it was the only one left at the party, 20 00:01:09,880 --> 00:01:13,560 Speaker 1: and I got a sneak peak of pre menopause. I 21 00:01:13,600 --> 00:01:17,360 Speaker 1: remember lying awake one night with never before experienced sort 22 00:01:17,360 --> 00:01:21,000 Speaker 1: of insomnia, not the familiar toss in turn routine, but 23 00:01:21,120 --> 00:01:25,960 Speaker 1: a razor sharp alertness, and this feverish heat. The nighttime 24 00:01:26,000 --> 00:01:28,800 Speaker 1: sounds gave way to the first morning traffic, then the 25 00:01:28,800 --> 00:01:31,319 Speaker 1: footfalls of my family walking on the floor above me, 26 00:01:32,000 --> 00:01:35,160 Speaker 1: and I registered all of it in this unrelenting, high 27 00:01:35,160 --> 00:01:39,000 Speaker 1: definition consciousness, and eventually I decided, I guess it's time 28 00:01:39,000 --> 00:01:41,560 Speaker 1: to get up and put some clothes on. And when 29 00:01:41,560 --> 00:01:44,120 Speaker 1: I rose, I saw the outline of my body on 30 00:01:44,160 --> 00:01:47,280 Speaker 1: the bedsheets. My sweat had traced the edges of me 31 00:01:47,360 --> 00:01:54,040 Speaker 1: in salt like police chalk on cotton. Most mammals remained 32 00:01:54,080 --> 00:01:56,040 Speaker 1: fertile all the way to the end of their lives, 33 00:01:56,520 --> 00:02:00,120 Speaker 1: and intuitively, that would seem like a strategic advantage the 34 00:02:00,160 --> 00:02:02,880 Speaker 1: whole get your genes out there board game of evolution. 35 00:02:03,520 --> 00:02:06,800 Speaker 1: So why is menopause only a thing for whales and women, 36 00:02:07,560 --> 00:02:09,720 Speaker 1: and on the human side of that equation, why do 37 00:02:09,760 --> 00:02:14,480 Speaker 1: we have such trouble talking to one another about the experience. Okay, first, 38 00:02:14,560 --> 00:02:19,680 Speaker 1: let's review basics paging. Dr Rosalind Jackson, an obstetrician, gynecologist 39 00:02:19,720 --> 00:02:24,120 Speaker 1: in Ohio. The average age for women going through menopause 40 00:02:24,240 --> 00:02:28,160 Speaker 1: is fifty one plus or minus three years, but ten 41 00:02:28,240 --> 00:02:30,959 Speaker 1: years prior to that is called the perimenal pausal time 42 00:02:31,000 --> 00:02:34,400 Speaker 1: of a woman's life, and during that time hormones start 43 00:02:34,480 --> 00:02:38,919 Speaker 1: to decrease. But it's when you become truly menopausal. It's 44 00:02:38,960 --> 00:02:41,400 Speaker 1: not to say that you've totally stopped making hormones at all, 45 00:02:41,639 --> 00:02:44,119 Speaker 1: but it's a very very small amount that you're producing, 46 00:02:44,720 --> 00:02:50,280 Speaker 1: quick and painless biochem refresher. The major sex hormones are estrogen, progesterone, 47 00:02:50,360 --> 00:02:53,399 Speaker 1: and testosterone, and all three hormones are found in both 48 00:02:53,400 --> 00:02:56,640 Speaker 1: men and women, but in different concentrations. Yes, ladies have 49 00:02:56,720 --> 00:03:01,000 Speaker 1: distosterone and guys have estrogen. During menopause, levels of these 50 00:03:01,040 --> 00:03:04,480 Speaker 1: hormones drop, and that change in body chemistry can affect 51 00:03:04,480 --> 00:03:07,840 Speaker 1: women in all sorts of ways. For some menopause isn't 52 00:03:07,840 --> 00:03:11,360 Speaker 1: really that big a deal. For others meaningfully alters what 53 00:03:11,440 --> 00:03:13,600 Speaker 1: it feels like to be alive in their own bodies, 54 00:03:13,880 --> 00:03:17,720 Speaker 1: with effects on mood and memory, they're thinking, and even 55 00:03:17,760 --> 00:03:20,280 Speaker 1: their sense of self. A lot of times they don't 56 00:03:20,320 --> 00:03:23,680 Speaker 1: associate some of the symptoms that they're having with menopause, 57 00:03:23,760 --> 00:03:26,560 Speaker 1: or that the fact that their hormones are decreasing, such 58 00:03:26,600 --> 00:03:30,720 Speaker 1: as um fatigue or insomnia. That's a really big one. 59 00:03:30,760 --> 00:03:34,320 Speaker 1: But commonly a lot of people do not associate the 60 00:03:34,320 --> 00:03:36,880 Speaker 1: inability to sleep with the fact that they're losing their 61 00:03:36,920 --> 00:03:41,160 Speaker 1: hormones or their hormones are decreasing. So there's fatigue, there's 62 00:03:41,280 --> 00:03:44,560 Speaker 1: I can't sleep, I can't lose weight. That's a big one. 63 00:03:44,880 --> 00:03:48,200 Speaker 1: Hot flashes, a nice sweat seems common, but it's not 64 00:03:48,440 --> 00:03:50,320 Speaker 1: the main thing that women come to see me for 65 00:03:50,440 --> 00:03:54,800 Speaker 1: regarding their hormones. Also, a decrease in libido, the integrity 66 00:03:54,840 --> 00:03:57,640 Speaker 1: of their skin, if they're losing hair. You have to 67 00:03:57,680 --> 00:03:59,839 Speaker 1: pull back all the layers to help a woman under 68 00:04:00,080 --> 00:04:02,920 Speaker 1: dan what's really going on with her body. You know, 69 00:04:03,040 --> 00:04:05,440 Speaker 1: it's it's very deep. How long does this part of 70 00:04:05,440 --> 00:04:08,200 Speaker 1: a woman's life last? You know, from the moment that 71 00:04:08,280 --> 00:04:11,600 Speaker 1: she starts to experience symptoms, like how much of her 72 00:04:11,640 --> 00:04:13,920 Speaker 1: life are we talking about now you are menopause or 73 00:04:13,960 --> 00:04:17,640 Speaker 1: you have no hormones, and so it's not like, oh, 74 00:04:17,680 --> 00:04:19,560 Speaker 1: for ten years, I'm gonna be bothered with this and 75 00:04:19,560 --> 00:04:22,080 Speaker 1: then I'm done with it. Right, So, yeah, it may 76 00:04:22,120 --> 00:04:25,200 Speaker 1: be true that you're not always bothered with hot flashes 77 00:04:25,240 --> 00:04:28,000 Speaker 1: or night swets, But what about the chemistry that's going 78 00:04:28,040 --> 00:04:30,600 Speaker 1: on your body? What about the fact that your metabolism 79 00:04:30,640 --> 00:04:32,680 Speaker 1: is different. You can't lose the weight that you could 80 00:04:32,760 --> 00:04:35,400 Speaker 1: when you were in your twenties or thirties. So those 81 00:04:35,520 --> 00:04:41,040 Speaker 1: kinds of metabolic changes are ongoing. Because menopause it's not 82 00:04:41,160 --> 00:04:43,640 Speaker 1: just a phase that you go through. It is like 83 00:04:43,839 --> 00:04:46,760 Speaker 1: this time in your life. It's like the woman you become. 84 00:04:58,000 --> 00:05:01,480 Speaker 1: Our cultural attitudes towards menopau eyes, along with the words 85 00:05:01,480 --> 00:05:04,279 Speaker 1: we use for it, have changed a lot over time. 86 00:05:04,800 --> 00:05:08,520 Speaker 1: Climate terek, the crisis, time of life, change of life, 87 00:05:08,839 --> 00:05:12,960 Speaker 1: the change and the gateway to death. My name is 88 00:05:13,000 --> 00:05:16,760 Speaker 1: Louise Foxcroft and I'm a historian and writer. I work 89 00:05:16,839 --> 00:05:18,880 Speaker 1: mainly in the history of medicine and I've written a 90 00:05:18,880 --> 00:05:21,360 Speaker 1: book called Hot Flush is called science the History of 91 00:05:21,360 --> 00:05:26,159 Speaker 1: the Modern Menopause. Louise has sifted through all sorts of 92 00:05:26,240 --> 00:05:32,040 Speaker 1: historical documents, diaries, old recipes, medical treatises, adds to get 93 00:05:32,080 --> 00:05:34,720 Speaker 1: a picture of how are thinking on menopause is evolved 94 00:05:35,120 --> 00:05:39,039 Speaker 1: earlier records, a early modern records. So it's seen fifty 95 00:05:39,040 --> 00:05:42,480 Speaker 1: and I'm talking you know British at this point, it's 96 00:05:42,640 --> 00:05:47,720 Speaker 1: mainly management, but it's tinged with this idea of what 97 00:05:48,000 --> 00:05:53,880 Speaker 1: women are and what women are is perceived through the 98 00:05:53,920 --> 00:05:57,800 Speaker 1: male I and one of the ideas that it's a 99 00:05:57,920 --> 00:06:01,600 Speaker 1: during the early modern time is that when you stop bleeding, 100 00:06:01,720 --> 00:06:04,160 Speaker 1: so when you hit menopause and you stop bleeding, the 101 00:06:04,240 --> 00:06:06,240 Speaker 1: blood has nowhere to go, so it stays in the 102 00:06:06,279 --> 00:06:08,840 Speaker 1: body and it corrupts the body because because we know 103 00:06:08,960 --> 00:06:11,039 Speaker 1: that the history of menstrual blood is that you know, 104 00:06:11,160 --> 00:06:14,000 Speaker 1: with his babies in the cradle, and mirrors cloud and 105 00:06:14,480 --> 00:06:19,040 Speaker 1: storms gather and flowers dye, milk, curdles, all that sort 106 00:06:19,080 --> 00:06:21,480 Speaker 1: of stuff. Monsters come out of dung heaps where your 107 00:06:21,560 --> 00:06:26,599 Speaker 1: rags are thrown. Okay, that warrants a restatement. People used 108 00:06:26,600 --> 00:06:29,279 Speaker 1: to think that women on their periods could curdle milk 109 00:06:29,680 --> 00:06:33,120 Speaker 1: and wilt flowers. Plenty of the elders said that menstrual 110 00:06:33,160 --> 00:06:36,719 Speaker 1: blood would take the edge of steel. Luise says that 111 00:06:36,760 --> 00:06:39,920 Speaker 1: our understanding of women's health is filtered through a medical 112 00:06:39,920 --> 00:06:43,719 Speaker 1: tradition that regards femaleness itself as a sort of affliction. 113 00:06:44,440 --> 00:06:46,640 Speaker 1: Just a heads up. The next few minutes include some 114 00:06:46,680 --> 00:06:49,800 Speaker 1: adult conversation that might not be appropriate for little listeners. 115 00:06:51,360 --> 00:06:55,760 Speaker 1: We are sort of physically unpleasant and emotionally unstable and 116 00:06:56,640 --> 00:06:59,680 Speaker 1: prone to vanity, and all sorts of indulgences and what 117 00:07:00,200 --> 00:07:05,000 Speaker 1: to our bodies is predicated upon those ideas of how 118 00:07:05,040 --> 00:07:07,160 Speaker 1: we are on the way that we behave, and so 119 00:07:07,760 --> 00:07:11,920 Speaker 1: generally you find you are treated in response to those ideas. 120 00:07:12,320 --> 00:07:15,600 Speaker 1: Can you list some of the most dramatic treatments that 121 00:07:15,680 --> 00:07:19,240 Speaker 1: have been administered to metopausal women? Yeah, so in the 122 00:07:19,320 --> 00:07:23,880 Speaker 1: nineteenth century, when it really kicks off, you might have 123 00:07:24,560 --> 00:07:28,040 Speaker 1: acetate of lead pumped into the vagina. You might have 124 00:07:28,040 --> 00:07:32,280 Speaker 1: a vaginal plug that well that's I mean, rags and 125 00:07:32,520 --> 00:07:36,440 Speaker 1: moss and various things have been used to instead of tampons, 126 00:07:36,440 --> 00:07:40,120 Speaker 1: just sort of early tampons. You might have an anal 127 00:07:40,160 --> 00:07:44,000 Speaker 1: injection of opium, so that some sort of narcotic which 128 00:07:44,120 --> 00:07:46,320 Speaker 1: was just not you for six you know, so, but 129 00:07:46,440 --> 00:07:50,400 Speaker 1: narcotic is a sort of every day analgesic first for everything. 130 00:07:50,600 --> 00:07:54,000 Speaker 1: Am I correct in thinking that in our most regrettable eras? 131 00:07:54,240 --> 00:07:59,080 Speaker 1: There were also surgical interventions? Yes, there were. There was cliterodectomy, 132 00:07:59,120 --> 00:08:08,200 Speaker 1: which is excision of the clitterers. Do you think that 133 00:08:08,320 --> 00:08:11,640 Speaker 1: women are less afraid of menopausean they used to be. 134 00:08:13,240 --> 00:08:15,920 Speaker 1: If you've placed your self worth in terms of how 135 00:08:15,960 --> 00:08:19,400 Speaker 1: you look and how you're perceived by men, mainly by men, 136 00:08:19,520 --> 00:08:23,080 Speaker 1: then I think women might dread menopause as they might 137 00:08:23,160 --> 00:08:26,360 Speaker 1: dread old age or the effects of aging. If you're 138 00:08:26,400 --> 00:08:31,120 Speaker 1: not worried about that, then I think you're happier. I 139 00:08:31,160 --> 00:08:33,680 Speaker 1: think the more women know about menopause, the less they'll 140 00:08:33,760 --> 00:08:40,200 Speaker 1: dread it. Marie Stops, the feminist and eugenicist who founded 141 00:08:40,240 --> 00:08:43,160 Speaker 1: the first birth control clinic in Britain in the nine twenties. 142 00:08:43,800 --> 00:08:46,400 Speaker 1: So there was also a gender power dynamic at play 143 00:08:46,800 --> 00:08:49,560 Speaker 1: that the menopause or the crisis of menopause, is a 144 00:08:49,600 --> 00:08:55,600 Speaker 1: manufactured crisis, and it's been created by male doctors. At 145 00:08:55,679 --> 00:08:59,520 Speaker 1: least as early as the nineteen thirties, pharmaceutical abs were 146 00:08:59,559 --> 00:09:03,560 Speaker 1: making hormone replacement therapies, pills, and creams that delivered sex 147 00:09:03,600 --> 00:09:06,440 Speaker 1: hormones back into a woman's body in order to reduce 148 00:09:06,480 --> 00:09:10,640 Speaker 1: menopausal symptoms. Some of the manufacturers of these products had 149 00:09:10,679 --> 00:09:14,280 Speaker 1: absolutely no qualms about taking the lowest of all available 150 00:09:14,360 --> 00:09:17,959 Speaker 1: low roads. The good one is endo Creme or endocream, 151 00:09:18,000 --> 00:09:21,720 Speaker 1: which was advertised in medical journals but also in women's magazines. 152 00:09:22,679 --> 00:09:25,520 Speaker 1: And that's the most glamorous photograph of a blonde and 153 00:09:25,600 --> 00:09:28,880 Speaker 1: she's staring up at her sort of clock gable lesque husband, 154 00:09:29,280 --> 00:09:32,200 Speaker 1: and he's looking down at her, and she's obviously applied 155 00:09:32,240 --> 00:09:34,199 Speaker 1: the endocream, rubbed it well in because you can't see it. 156 00:09:34,240 --> 00:09:37,000 Speaker 1: But the tagline is how long is it since he 157 00:09:37,080 --> 00:09:42,119 Speaker 1: said I love you? The thing is, ladies don't get 158 00:09:42,160 --> 00:09:45,320 Speaker 1: older and don't have a menopause because men will no 159 00:09:45,400 --> 00:09:49,599 Speaker 1: longer love you. In the US, the number one prescription 160 00:09:49,720 --> 00:09:52,720 Speaker 1: in the eighties and nineties was a hormone pill called Premarin. 161 00:09:53,360 --> 00:09:56,280 Speaker 1: Since then, there's been a lot of controversy about hormone 162 00:09:56,320 --> 00:10:00,640 Speaker 1: replacement therapy. Some studies have associated it within creased rates 163 00:10:00,640 --> 00:10:04,880 Speaker 1: of cancer and other serious health risks. Okay, let's leave 164 00:10:04,880 --> 00:10:08,040 Speaker 1: the chemistry and horrifying marketing copy behind for a moment 165 00:10:08,320 --> 00:10:13,760 Speaker 1: and head instead for open water. It's time to talk whales. 166 00:10:14,800 --> 00:10:17,160 Speaker 1: I'm Darren Croft. I work at the University of extra 167 00:10:17,240 --> 00:10:24,040 Speaker 1: and I'm a professor in animal behavior. Your specialty technically 168 00:10:24,120 --> 00:10:29,280 Speaker 1: is behavioral ecology. Yes, it's the study of behavior in 169 00:10:29,320 --> 00:10:34,440 Speaker 1: an ecological setting, so understanding how the environment has shaped 170 00:10:34,520 --> 00:10:37,000 Speaker 1: the behavior of animals. Does that essentially mean that you're 171 00:10:37,000 --> 00:10:39,880 Speaker 1: also studying the way that animals interact with each other 172 00:10:39,960 --> 00:10:44,000 Speaker 1: and with their larger environment as opposed to an individual. Yes, definitely. 173 00:10:52,120 --> 00:10:54,480 Speaker 1: As a high school student, I spent most of my 174 00:10:54,559 --> 00:10:59,720 Speaker 1: time wandering around in streams and fields and just studying animals. 175 00:10:59,760 --> 00:11:03,560 Speaker 1: And fast forward around twenty years or something to hanging 176 00:11:03,600 --> 00:11:10,080 Speaker 1: around in boats and looking at killer whales, trying to 177 00:11:10,160 --> 00:11:16,959 Speaker 1: understand how the world works. In the mammalian world, it's 178 00:11:17,040 --> 00:11:20,080 Speaker 1: pretty much just us and a handful of toothed whale 179 00:11:20,120 --> 00:11:23,559 Speaker 1: species that go through menopause, including orcas a k a. 180 00:11:23,720 --> 00:11:27,040 Speaker 1: Killer whales and Norwall's arguably the A Listers of the 181 00:11:27,080 --> 00:11:31,360 Speaker 1: whale world. Darren and his student Emma Foster studied more 182 00:11:31,400 --> 00:11:34,240 Speaker 1: than forty years of all the birth and death records 183 00:11:34,320 --> 00:11:36,959 Speaker 1: for two groups of killer whales off the western coast 184 00:11:37,000 --> 00:11:40,559 Speaker 1: of North America. Emma had a suspicion that there might 185 00:11:40,600 --> 00:11:43,000 Speaker 1: be some patterns in these birth and death records that 186 00:11:43,040 --> 00:11:46,839 Speaker 1: could explain whale menopause, so she and Darren dove into 187 00:11:46,840 --> 00:11:50,920 Speaker 1: the data. I swear on my honor that was an 188 00:11:50,920 --> 00:11:58,160 Speaker 1: accidental dive plan and it will not happen again. One 189 00:11:58,200 --> 00:12:00,960 Speaker 1: important point about these animals, and it's absolutely key to 190 00:12:01,080 --> 00:12:05,719 Speaker 1: understanding why menopause is evolved in this system, is that 191 00:12:05,960 --> 00:12:09,200 Speaker 1: in most animals, one of the sex will disperse from 192 00:12:09,200 --> 00:12:12,640 Speaker 1: from the family group, and in this species, sons and 193 00:12:12,720 --> 00:12:15,360 Speaker 1: daughters stay with their mother, and that's absolutely crucial to 194 00:12:15,480 --> 00:12:20,920 Speaker 1: understanding why menopause is evolved. Okay, so whales are special 195 00:12:20,920 --> 00:12:23,520 Speaker 1: and weird because the kids stay with ma even after 196 00:12:23,559 --> 00:12:27,040 Speaker 1: they're grown up. Not a crystal clear connection with menopause yet, 197 00:12:27,160 --> 00:12:29,520 Speaker 1: but I'm tracking. But that means that you've got adult 198 00:12:29,640 --> 00:12:32,200 Speaker 1: sons hanging around with their mothers. So we were able 199 00:12:32,280 --> 00:12:34,520 Speaker 1: to look at what the effects of a mother death 200 00:12:34,760 --> 00:12:37,720 Speaker 1: was on her son's survival, and we found a huge effect. 201 00:12:38,240 --> 00:12:41,199 Speaker 1: The data showed that if an adult males mom died, 202 00:12:41,679 --> 00:12:44,440 Speaker 1: his chance of dying shut up to his hazard of 203 00:12:44,440 --> 00:12:48,520 Speaker 1: mortality increases by more than eight times. So they really 204 00:12:48,559 --> 00:12:52,920 Speaker 1: are keeping their sons alive. So how exactly are older 205 00:12:52,960 --> 00:12:56,000 Speaker 1: moms keeping their adult sons alive. One of the ways 206 00:12:56,000 --> 00:12:59,720 Speaker 1: they're doing is by feeding them. Amazingly, say you've got 207 00:12:59,760 --> 00:13:04,360 Speaker 1: the sixty plus year old females catching salmon and actually 208 00:13:04,640 --> 00:13:07,400 Speaker 1: sharing that fish, you know, ripping that fish in half 209 00:13:07,679 --> 00:13:12,800 Speaker 1: and directly feeding these fully grown, huge male offspring. These 210 00:13:12,840 --> 00:13:19,320 Speaker 1: adults male killer whales sound like the least datable people. Well, 211 00:13:19,360 --> 00:13:21,319 Speaker 1: they only go one very short dates because then they 212 00:13:21,360 --> 00:13:25,679 Speaker 1: returned back to their mothers. They literally are swimming by 213 00:13:25,720 --> 00:13:33,360 Speaker 1: their mum's side most of their life. While dude whales 214 00:13:33,480 --> 00:13:36,960 Speaker 1: typically die in their thirties, lady whales stop having calves 215 00:13:36,960 --> 00:13:40,240 Speaker 1: in their thirties or forties, but live for decades longer. 216 00:13:40,800 --> 00:13:44,160 Speaker 1: They spend this post reproductive stage of their lives helping 217 00:13:44,160 --> 00:13:48,160 Speaker 1: their grown children and their grandchildren. And because old females 218 00:13:48,200 --> 00:13:50,600 Speaker 1: have been around the water block so many times, they're 219 00:13:50,640 --> 00:13:54,720 Speaker 1: particularly formidable when it comes to the hunt. One of 220 00:13:54,760 --> 00:13:57,760 Speaker 1: the things that we know is that they are really 221 00:13:57,800 --> 00:14:00,560 Speaker 1: important in finding the food in the first place. I mean, 222 00:14:00,600 --> 00:14:03,520 Speaker 1: if you think about these whiles swimming around in this ocean, 223 00:14:04,120 --> 00:14:07,480 Speaker 1: and these salmon are locally abundant, coming to the rivers 224 00:14:07,480 --> 00:14:11,200 Speaker 1: in their masses to spawn, but not all rivers have 225 00:14:11,280 --> 00:14:13,280 Speaker 1: fish at the same time, So it's a case of 226 00:14:13,320 --> 00:14:16,000 Speaker 1: knowing when and where to look for food. And it's 227 00:14:16,040 --> 00:14:19,880 Speaker 1: these old post reproductive females that are guiding their family 228 00:14:19,920 --> 00:14:22,920 Speaker 1: group around to find the fish. So it's that knowledge 229 00:14:22,920 --> 00:14:25,400 Speaker 1: that they've accumulated through their life is one of the 230 00:14:25,400 --> 00:14:27,600 Speaker 1: ways that they're helping to keep their family group alive. 231 00:14:28,680 --> 00:14:32,840 Speaker 1: So here's the crucial bit. For whales, a grandmother's energy 232 00:14:33,040 --> 00:14:36,040 Speaker 1: is better spent on existing offspring than on mating to 233 00:14:36,120 --> 00:14:39,240 Speaker 1: make more offspring. Her jeans have the best chance of 234 00:14:39,320 --> 00:14:42,080 Speaker 1: carrying on into the future if she devotes her attention, 235 00:14:42,280 --> 00:14:45,320 Speaker 1: her knowledge, and her resources to her adult descendants and 236 00:14:45,360 --> 00:14:49,840 Speaker 1: their young rude rather than getting pregnant again herself. A 237 00:14:49,880 --> 00:14:53,640 Speaker 1: lot of anthropologists and evolutionary scientists are trying to find 238 00:14:53,680 --> 00:14:56,800 Speaker 1: out if human behavior can be explained in the same way, 239 00:14:57,160 --> 00:15:00,680 Speaker 1: if menopause is an evolved adaptation that direct our time 240 00:15:00,680 --> 00:15:04,040 Speaker 1: and attention to our adult kids and their families. In 241 00:15:04,080 --> 00:15:08,000 Speaker 1: a fit of literalism, scientists call this the grandmother hypothesis. 242 00:15:16,840 --> 00:15:21,480 Speaker 1: If grand offspring really benefit in killer whale populations and 243 00:15:21,520 --> 00:15:25,360 Speaker 1: potentially in human populations um from having their grandmother around 244 00:15:25,400 --> 00:15:28,160 Speaker 1: even when she's postfertile, then why don't we see it 245 00:15:28,200 --> 00:15:31,000 Speaker 1: in a lot of other species that live together in 246 00:15:31,120 --> 00:15:34,080 Speaker 1: social groups. Yeah, So, I mean, it's a really good 247 00:15:34,160 --> 00:15:37,479 Speaker 1: question because we know that there are these grandmother effects 248 00:15:37,520 --> 00:15:42,040 Speaker 1: in other species. So elephant societies for example, the grandmothers 249 00:15:42,040 --> 00:15:45,240 Speaker 1: are really important in keeping their grand offspring alive and 250 00:15:45,280 --> 00:15:48,400 Speaker 1: their offspring alive and similar mechanisms. You know, they know 251 00:15:48,480 --> 00:15:50,720 Speaker 1: how to respond to predators or they know where to 252 00:15:50,760 --> 00:15:56,080 Speaker 1: find water. With elephants, an old female can help out 253 00:15:56,120 --> 00:15:58,880 Speaker 1: as grandmother while still having new babies of our own. 254 00:15:59,360 --> 00:16:03,080 Speaker 1: But for way as their social structure and ecological conditions 255 00:16:03,360 --> 00:16:07,440 Speaker 1: mean that younger and older generations would be competing for resources. 256 00:16:07,840 --> 00:16:10,000 Speaker 1: The key thing is with these resident killer whales is 257 00:16:10,040 --> 00:16:13,240 Speaker 1: that when the females are reaching and that they've got 258 00:16:13,280 --> 00:16:16,280 Speaker 1: their adult offspring around, there is a real opportunity there 259 00:16:16,280 --> 00:16:18,960 Speaker 1: for them to help. Whereas you know, it'd be hard 260 00:16:19,000 --> 00:16:21,880 Speaker 1: to imagine a way that an elephant or another long 261 00:16:21,960 --> 00:16:24,600 Speaker 1: lived social mammal might be able to do that in 262 00:16:24,640 --> 00:16:28,000 Speaker 1: the same way because of diet, because the herbivores, because 263 00:16:28,040 --> 00:16:30,840 Speaker 1: I can't catch a tree, right, the trees just actually 264 00:16:30,920 --> 00:16:34,720 Speaker 1: the trees, they're they're grazing, they're browsing. And you know, 265 00:16:34,760 --> 00:16:37,880 Speaker 1: if we look at other long lived mammals such as elephants, 266 00:16:37,920 --> 00:16:41,160 Speaker 1: for example, they're not sharing food in the in the 267 00:16:41,200 --> 00:16:44,920 Speaker 1: same way that the killer whales are, and indeed, ancestral 268 00:16:45,040 --> 00:16:49,480 Speaker 1: humans were sharing and helping to prepare food. So it 269 00:16:49,560 --> 00:16:53,160 Speaker 1: really is the ecology, the environment that diet their life. 270 00:16:53,200 --> 00:16:56,640 Speaker 1: That's It's all a combination of factors and it is 271 00:16:56,800 --> 00:17:00,680 Speaker 1: very unusual that you get these effects coming together, which 272 00:17:00,720 --> 00:17:07,600 Speaker 1: is why menopause is so rare in the animal kingdom. Okay, 273 00:17:07,720 --> 00:17:11,399 Speaker 1: a quick aside before moving on. Fertility functions in different 274 00:17:11,400 --> 00:17:15,440 Speaker 1: ways in humans and whales. For women, menopause is signaled 275 00:17:15,480 --> 00:17:18,919 Speaker 1: by the cessation of a woman's menstrual cycle, but whales 276 00:17:18,960 --> 00:17:21,840 Speaker 1: don't have periods, and so researchers can only tell if 277 00:17:21,840 --> 00:17:25,200 Speaker 1: they're post fertile by measuring the hormonal levels in their pooh, 278 00:17:25,520 --> 00:17:27,800 Speaker 1: which they locate floating on the surface of the water 279 00:17:27,880 --> 00:17:30,240 Speaker 1: with sniffer dogs, the most famous one of which is 280 00:17:30,280 --> 00:17:34,679 Speaker 1: a Labrador Retriever named Tucker. Listener the World is Wide, 281 00:17:35,560 --> 00:17:39,440 Speaker 1: Louis Foxcroft, our menopause historian, says, it's important that all 282 00:17:39,480 --> 00:17:42,439 Speaker 1: of us boys and girls know more about this stuff, 283 00:17:43,119 --> 00:17:45,600 Speaker 1: more about our own bodies. Is not about Tucker the labrador. 284 00:17:45,920 --> 00:17:49,280 Speaker 1: In schools where they have sex education, they need to 285 00:17:49,320 --> 00:17:53,800 Speaker 1: talk about menopause thenteen year old, they need to know 286 00:17:53,880 --> 00:17:57,479 Speaker 1: about the whole of their reproductive lives. Wow. That has 287 00:17:57,520 --> 00:17:59,320 Speaker 1: not occurred to me until this moment, but I wish 288 00:17:59,359 --> 00:18:02,439 Speaker 1: that in my it like junior high in high school, 289 00:18:02,440 --> 00:18:06,640 Speaker 1: sex said, which was so profoundly uncomfortable for so many reasons. Right, 290 00:18:06,680 --> 00:18:09,000 Speaker 1: it's a weird class. I wish they had talked about 291 00:18:09,000 --> 00:18:11,560 Speaker 1: the menopause, not necessarily because I would have been in 292 00:18:11,600 --> 00:18:13,359 Speaker 1: a position that it's going to better equip me for 293 00:18:13,440 --> 00:18:18,040 Speaker 1: my own menopause, but because I would have loved, like 294 00:18:18,119 --> 00:18:23,440 Speaker 1: a very swift jab to the ribs to like think 295 00:18:23,480 --> 00:18:26,320 Speaker 1: about my mother in a more compassionate way. And in 296 00:18:26,400 --> 00:18:29,800 Speaker 1: researching this podcast, I texted her like, I am so 297 00:18:29,840 --> 00:18:33,000 Speaker 1: sorry that I was totally tone deaf to like a 298 00:18:33,119 --> 00:18:35,840 Speaker 1: really big part of your life when you have not 299 00:18:36,000 --> 00:18:38,520 Speaker 1: been even when we fought, like you've not been tone 300 00:18:38,560 --> 00:18:41,560 Speaker 1: deaf and completely oblivious, right, like these big things that 301 00:18:41,560 --> 00:18:43,959 Speaker 1: are happening to mind. Well, I lost my mother when 302 00:18:44,000 --> 00:18:46,119 Speaker 1: I was thirty five, so I never got to have 303 00:18:46,200 --> 00:18:48,240 Speaker 1: that conversation with her, and I would really like to 304 00:18:48,280 --> 00:18:50,720 Speaker 1: have that conversation. And I remember her having the menopause, 305 00:18:50,880 --> 00:18:53,600 Speaker 1: and I remember her struggling with it, and I didn't 306 00:18:53,840 --> 00:18:56,159 Speaker 1: really you know, I had no conception of what was 307 00:18:56,200 --> 00:18:58,520 Speaker 1: going on. And we didn't talk about it because I 308 00:18:58,520 --> 00:19:03,280 Speaker 1: think that generation of women she was born in didn't 309 00:19:03,320 --> 00:19:10,760 Speaker 1: discuss it. With that note on the importance of intergenerational conversation, 310 00:19:11,240 --> 00:19:15,280 Speaker 1: I'll usher in our final guest. My name is Bob Wander, 311 00:19:15,920 --> 00:19:20,119 Speaker 1: and how did we meet? I am the father of 312 00:19:20,240 --> 00:19:26,200 Speaker 1: the interviewer. Actually we met in the hospital during your 313 00:19:26,280 --> 00:19:32,600 Speaker 1: birthing process. I remember the day very clearly. Reading scientists 314 00:19:32,800 --> 00:19:36,439 Speaker 1: arguments for and against the grandmother hypothesis made me think 315 00:19:36,480 --> 00:19:39,119 Speaker 1: about my own grandma. When I was very small. She 316 00:19:39,240 --> 00:19:41,240 Speaker 1: took care of me a few nights a week. When 317 00:19:41,240 --> 00:19:43,760 Speaker 1: I got big, we ate lunch together at a dumb 318 00:19:43,800 --> 00:19:46,800 Speaker 1: sports bar. Why drank coffee, and she ordered a Manhattan 319 00:19:46,840 --> 00:19:49,960 Speaker 1: and always picked up the tab, which incidentally is pretty 320 00:19:50,040 --> 00:19:53,040 Speaker 1: much exactly what the grandmother hypothesis would predict, both the 321 00:19:53,119 --> 00:19:57,280 Speaker 1: childcare and the resource sharing. I still sometimes wear Jeanette's 322 00:19:57,280 --> 00:20:00,040 Speaker 1: wedding ring on a chain around my neck. She and 323 00:20:00,080 --> 00:20:03,959 Speaker 1: I were close, but she and my dad were really close. 324 00:20:04,800 --> 00:20:08,960 Speaker 1: Do you feel like you understood her? I do. Did 325 00:20:09,000 --> 00:20:13,880 Speaker 1: you feel understood by her? Probably better by her than 326 00:20:13,920 --> 00:20:16,719 Speaker 1: just about anybody else on earth, To be honest, do 327 00:20:16,760 --> 00:20:20,920 Speaker 1: you know what her experience of menopause was like, that's 328 00:20:20,920 --> 00:20:23,680 Speaker 1: a good question. I really don't know. I was too 329 00:20:23,720 --> 00:20:27,600 Speaker 1: young to know much biology when she was menopausal, and 330 00:20:27,760 --> 00:20:29,399 Speaker 1: I was also kind of on my way out of 331 00:20:29,400 --> 00:20:31,639 Speaker 1: the household at a relatively young age to be on 332 00:20:31,680 --> 00:20:35,000 Speaker 1: my own. Okay, I'm going to do a quick fact 333 00:20:35,080 --> 00:20:37,040 Speaker 1: check with your dad. Are you saying that when you 334 00:20:37,080 --> 00:20:40,040 Speaker 1: went up to college you didn't know the biology of menopause. 335 00:20:41,119 --> 00:20:43,280 Speaker 1: I knew a little bit about it, but the only 336 00:20:43,359 --> 00:20:45,720 Speaker 1: female in the household where I grew up was my mother. 337 00:20:45,840 --> 00:20:50,800 Speaker 1: I had four brothers, so I knew very little about 338 00:20:50,800 --> 00:20:53,760 Speaker 1: what was going down. To be perfectly honest, my dad 339 00:20:53,800 --> 00:20:56,680 Speaker 1: and his mom shared secrets. They confided in one another 340 00:20:56,720 --> 00:20:59,879 Speaker 1: about their marriages, the sweet stuff and the lousy and 341 00:21:00,080 --> 00:21:02,600 Speaker 1: only stuff too. So it struck me as a little 342 00:21:02,600 --> 00:21:05,359 Speaker 1: strange that what might have been a really important experience 343 00:21:05,400 --> 00:21:08,199 Speaker 1: for her was never really mentioned between them. Even in 344 00:21:08,240 --> 00:21:11,840 Speaker 1: passing years later, when my ovary had to come out, 345 00:21:12,119 --> 00:21:14,240 Speaker 1: my dad got really involved with the science of the 346 00:21:14,240 --> 00:21:18,159 Speaker 1: female reproductive system, Like, in order to understand my experience, 347 00:21:18,320 --> 00:21:21,560 Speaker 1: he wanted to understand the biology of me. I remember 348 00:21:21,600 --> 00:21:26,440 Speaker 1: your diagnosis and treatment very well. These subjects for public 349 00:21:26,560 --> 00:21:28,879 Speaker 1: discussion were really kind of taboo when I was a 350 00:21:28,960 --> 00:21:32,840 Speaker 1: very young person, at least in Central North America, and 351 00:21:32,880 --> 00:21:35,200 Speaker 1: they're not now. So I think the level of knowledge 352 00:21:35,240 --> 00:21:38,600 Speaker 1: that everybody has about the number of as I said, 353 00:21:38,600 --> 00:21:41,960 Speaker 1: gender identity issues and female biological issues, the level of 354 00:21:42,000 --> 00:21:45,240 Speaker 1: general education is much higher now than it was when 355 00:21:45,240 --> 00:21:50,520 Speaker 1: I was a very young person. That is better, I do. Yeah, 356 00:21:50,560 --> 00:21:53,560 Speaker 1: I think sunlight is the best disinfectant. I didn't invent 357 00:21:53,640 --> 00:21:56,080 Speaker 1: that phrase, but if I had invented it, I would 358 00:21:56,119 --> 00:22:01,480 Speaker 1: be proud of it. Net was a pretty stellar mother, 359 00:22:02,040 --> 00:22:05,560 Speaker 1: loving but also shrewd and quick. If she were a 360 00:22:05,640 --> 00:22:07,800 Speaker 1: killer whale, she would have been the ferocious hunter to 361 00:22:07,840 --> 00:22:11,399 Speaker 1: stuff all her sons with fish. And if menopause is 362 00:22:11,440 --> 00:22:13,760 Speaker 1: partly to thank for the way that human children are raised, 363 00:22:13,960 --> 00:22:16,159 Speaker 1: then it's a huge factor that shaped a lot of 364 00:22:16,160 --> 00:22:19,840 Speaker 1: our families in a mostly unrecognized way. On my next 365 00:22:19,880 --> 00:22:22,399 Speaker 1: visit with my dad, I've already made plans to have 366 00:22:22,440 --> 00:22:25,840 Speaker 1: a salmon dinner in Jeanette's honor salmon, and maybe a 367 00:22:25,920 --> 00:22:32,280 Speaker 1: Manhattan too. On the next Deeply Human, why do you 368 00:22:32,320 --> 00:22:35,320 Speaker 1: listen to sad music? Like? If we're generally trying to 369 00:22:35,400 --> 00:22:38,320 Speaker 1: lead happy lives, how come we subject ourselves. Two songs 370 00:22:38,320 --> 00:22:41,520 Speaker 1: that choke us up. The song can feel like you're 371 00:22:41,520 --> 00:22:44,520 Speaker 1: communing with an artist who understands and has been through 372 00:22:44,640 --> 00:22:48,600 Speaker 1: what you've gone through, and so it's not necessarily hopeless 373 00:22:48,600 --> 00:22:50,960 Speaker 1: because here's somebody who clearly went through some of the 374 00:22:50,960 --> 00:22:52,760 Speaker 1: same things that I did and came out on the 375 00:22:52,800 --> 00:22:56,960 Speaker 1: other side and wrote a song about it. Deeply Human 376 00:22:57,080 --> 00:22:59,520 Speaker 1: is a co production of the BBC World Service in 377 00:22:59,600 --> 00:23:02,800 Speaker 1: America in Public Media with I Heart Media, and it's 378 00:23:02,840 --> 00:23:06,640 Speaker 1: hosted by me Deessa.
