8
00:00:26,480 --> 00:00:28,920
Speaker 1: the podcast. I'm Josh Clark Stafford or here at How

9
00:00:28,960 --> 00:00:33,160
Speaker 1: Stuff Works dot Com with me, as always is Charles W. Bryant. Chuck.

10
00:00:33,280 --> 00:00:36,760
Speaker 1: What's going on? It's good to be here, Josh as always. Yeah, Yeah,

11
00:00:36,800 --> 00:00:39,280
Speaker 1: I'm feeling the same way, Chuck. I'm feeling that pretty good.

12
00:00:39,560 --> 00:00:42,000
Speaker 1: So you guys might not know this, but Chuck always

13
00:00:42,040 --> 00:00:45,560
Speaker 1: kind of keeps me abreast of current events, situations going

14
00:00:45,600 --> 00:00:48,360
Speaker 1: on in the world. Would you have for me today, Chuck? Today, Josh,

15
00:00:48,400 --> 00:00:51,879
Speaker 1: I have the cause of death results for legendary soulsinger

16
00:00:51,920 --> 00:00:55,040
Speaker 1: Isaac Hayes. Yes, the man who scored Shaft died recently.

17
00:00:56,240 --> 00:00:59,320
Speaker 1: I'm Jim. Yes he did. He died apparently while jogging

18
00:00:59,320 --> 00:01:04,160
Speaker 1: on his treadmill, which is um very sad. Yes, and

19
00:01:04,480 --> 00:01:07,240
Speaker 1: it looks like the cause of death is uh stroke

20
00:01:07,440 --> 00:01:10,039
Speaker 1: because of high blood pressure. You know, that's funny that

21
00:01:10,080 --> 00:01:11,800
Speaker 1: you bring that up, because I've been wanting to talk

22
00:01:11,840 --> 00:01:15,320
Speaker 1: about high blood pressure also known as hypertension for a while. Lately.

23
00:01:15,360 --> 00:01:17,920
Speaker 1: I'm feeling like this's a good opportunity to do it. Right, Yeah,

24
00:01:18,000 --> 00:01:20,080
Speaker 1: let's do it. You know how stuff works. Stuff You

25
00:01:20,080 --> 00:01:22,720
Speaker 1: should know. It's not always just fun and games. Sometimes

26
00:01:23,120 --> 00:01:25,679
Speaker 1: we want to help people out with a little health advice. Agreed,

27
00:01:25,720 --> 00:01:28,000
Speaker 1: So so let's do that, right, let's do it. Well, Chuck,

28
00:01:28,440 --> 00:01:31,200
Speaker 1: this doesn't in any way, shape or form qualify me

29
00:01:31,240 --> 00:01:34,120
Speaker 1: as any kind of medical professional. But I spent a

30
00:01:34,160 --> 00:01:36,080
Speaker 1: trimester in E m T School. Do you know that

31
00:01:36,120 --> 00:01:39,480
Speaker 1: about it? Yeah? Yeah, seriously, I had no idea I did, uh,

32
00:01:39,560 --> 00:01:41,679
Speaker 1: and I was terrible at it um. For the final

33
00:01:41,720 --> 00:01:44,840
Speaker 1: exam for the trimester, uh, the instructor brought in some

34
00:01:44,959 --> 00:01:46,920
Speaker 1: of his former students who are now E m T

35
00:01:47,160 --> 00:01:49,400
Speaker 1: s and they acted like they were suffering from some

36
00:01:49,480 --> 00:01:52,960
Speaker 1: sort of uh terrible medical condition and we had to

37
00:01:52,960 --> 00:01:55,559
Speaker 1: figure it out based on the symptoms. Right. Well, I

38
00:01:55,680 --> 00:01:59,720
Speaker 1: am a terrible diagnostician. Um, I I landed a victim.

39
00:01:59,760 --> 00:02:03,480
Speaker 1: I just made air quotes who was choking? And I

40
00:02:03,560 --> 00:02:06,400
Speaker 1: treated her like a burn victim, um, and laid her down,

41
00:02:06,480 --> 00:02:09,760
Speaker 1: and I think I started doing CPR or something on her.

42
00:02:09,800 --> 00:02:12,440
Speaker 1: And I knew that I had completely missed the mark

43
00:02:12,680 --> 00:02:15,000
Speaker 1: when she looked over at the instructor with this what

44
00:02:15,040 --> 00:02:17,280
Speaker 1: the heck should I do now? Expression? And He's just like,

45
00:02:17,360 --> 00:02:19,840
Speaker 1: keep going, keep going. She grabbed her throat and you

46
00:02:19,919 --> 00:02:23,000
Speaker 1: thought that she had burned her neck pretty pretty much. Yeah, yeah,

47
00:02:23,520 --> 00:02:26,600
Speaker 1: I failed miserably. Um, But there were a couple of

48
00:02:26,639 --> 00:02:29,200
Speaker 1: things I learned. One of them was how important it

49
00:02:29,240 --> 00:02:31,079
Speaker 1: is to take care of the old ticker. I mean,

50
00:02:31,160 --> 00:02:33,079
Speaker 1: we're we're getting to be about that age, chuck. I

51
00:02:33,120 --> 00:02:36,480
Speaker 1: hate to break it to you. I just reached thirty two.

52
00:02:36,560 --> 00:02:40,480
Speaker 1: I'm very depressed about that. But five onto that, my friend. Yeah,

53
00:02:41,720 --> 00:02:45,160
Speaker 1: so you're pushing forty now pushing, Yeah, and and neither

54
00:02:45,200 --> 00:02:48,120
Speaker 1: one of us are in prime physical condition, right, I

55
00:02:48,160 --> 00:02:51,600
Speaker 1: think that's a fair assessment. Yeah. Yeah, So I'm no triathlete, no,

56
00:02:51,800 --> 00:02:54,320
Speaker 1: And I love bacon. I love it. I love it

57
00:02:54,400 --> 00:02:56,800
Speaker 1: so much I can't even begin to tell you. But

58
00:02:57,080 --> 00:03:00,280
Speaker 1: one of the problems with bacon is that fat that

59
00:03:00,360 --> 00:03:03,240
Speaker 1: we eat and digest gets carried through the blood stream,

60
00:03:03,639 --> 00:03:06,440
Speaker 1: and uh, it doesn't always break down like it should know.

61
00:03:06,800 --> 00:03:10,760
Speaker 1: It starts to form plaque within blood vessels, which actually

62
00:03:10,880 --> 00:03:15,200
Speaker 1: can lead to hypertension. And you want to know how well,

63
00:03:15,600 --> 00:03:17,240
Speaker 1: first of all, I think we should just tell people

64
00:03:17,280 --> 00:03:20,440
Speaker 1: what blood pressure is, period because people hear the blood

65
00:03:20,440 --> 00:03:23,160
Speaker 1: pressure and they don't understand what it is. It's really simple.

66
00:03:23,160 --> 00:03:25,840
Speaker 1: Blood pressure actually is all it is is the measurement

67
00:03:26,200 --> 00:03:29,760
Speaker 1: of the force of the blood going through your arteries

68
00:03:30,080 --> 00:03:33,079
Speaker 1: against the artery walls. Yeah, your your heart actually UM

69
00:03:33,520 --> 00:03:37,640
Speaker 1: creates it generates an electrical impulse. The the electrical impulse

70
00:03:37,680 --> 00:03:40,160
Speaker 1: travels across the heart and it's picked up by the atria,

71
00:03:40,200 --> 00:03:43,440
Speaker 1: which is which contracts. Right, the blood is forced out

72
00:03:43,440 --> 00:03:45,760
Speaker 1: of the heart and into the blood vessels. So there

73
00:03:45,760 --> 00:03:48,920
Speaker 1: you've got. You've got your systolic pressure, which is the

74
00:03:48,960 --> 00:03:52,120
Speaker 1: first number on a blood pressure reading, right, it's something

75
00:03:52,200 --> 00:03:54,400
Speaker 1: over something and that's that's the first one, the one

76
00:03:54,400 --> 00:03:57,640
Speaker 1: on top. And the optimal for systolic pressure I think

77
00:03:57,720 --> 00:04:00,360
Speaker 1: is like one twenty for the average healthy adults once

78
00:04:00,360 --> 00:04:02,640
Speaker 1: twenty year or under is what you're looking for right now.

79
00:04:02,720 --> 00:04:06,240
Speaker 1: UM to measure this kind of thing, it's it's luckily right.

80
00:04:06,520 --> 00:04:09,440
Speaker 1: We don't need trepid nation or any kind of rectal exam.

81
00:04:09,480 --> 00:04:11,960
Speaker 1: You can just slap a blood pressure cuff on your arm,

82
00:04:12,600 --> 00:04:15,200
Speaker 1: and thanks to our good friend Mercury, we can measure

83
00:04:15,200 --> 00:04:18,640
Speaker 1: the pressure exerted on any given blood vessel. Is the

84
00:04:18,640 --> 00:04:21,799
Speaker 1: blood car pumps through it? Right? And I I personally

85
00:04:22,240 --> 00:04:24,320
Speaker 1: love those things when you get your blood pressure checked.

86
00:04:24,320 --> 00:04:26,200
Speaker 1: Ever since I was a kid, I just thought when

87
00:04:26,240 --> 00:04:28,560
Speaker 1: the when it constricts around your arm and tightens up

88
00:04:28,560 --> 00:04:30,480
Speaker 1: and you can feel your heart beating in your arm,

89
00:04:30,800 --> 00:04:32,560
Speaker 1: I just thought it was really neat. And chances are

90
00:04:32,600 --> 00:04:35,360
Speaker 1: if you go to a grocery store a drug store,

91
00:04:35,440 --> 00:04:37,760
Speaker 1: you might find me sitting at one of their little machines.

92
00:04:38,160 --> 00:04:39,720
Speaker 1: It's a it's a great thing. It's a great way

93
00:04:39,760 --> 00:04:42,240
Speaker 1: to pass the time. Yeah, but it's not. Actually, I

94
00:04:42,240 --> 00:04:44,880
Speaker 1: did some research. It's not always the most accurate read.

95
00:04:45,000 --> 00:04:47,520
Speaker 1: So people need to know this when they get their

96
00:04:47,520 --> 00:04:51,760
Speaker 1: blood pressure checked by machine at your local Kroger. Uh.

97
00:04:51,800 --> 00:04:53,640
Speaker 1: It may have been accurate when they first installed it,

98
00:04:53,680 --> 00:04:56,599
Speaker 1: but it needs to be maintained and recalibrated over the years,

99
00:04:56,920 --> 00:04:58,720
Speaker 1: so if it's not, it may be off you. You

100
00:04:58,800 --> 00:05:00,880
Speaker 1: might can get a good idea that you should look

101
00:05:00,880 --> 00:05:03,560
Speaker 1: into it further, but you shouldn't, you know, make any

102
00:05:04,120 --> 00:05:07,040
Speaker 1: medical decisions based on what you uh, what you get

103
00:05:07,040 --> 00:05:08,840
Speaker 1: when you're picking out your hot dog buttons and you're

104
00:05:09,920 --> 00:05:12,760
Speaker 1: we we hear how stuff works. Strongly advise you to

105
00:05:12,800 --> 00:05:16,839
Speaker 1: console the physician for just about anything, including blood pressure readings.

106
00:05:16,839 --> 00:05:18,960
Speaker 1: But yeah, at the very least, it's it's kind of

107
00:05:18,960 --> 00:05:21,880
Speaker 1: a joy to have your arms squeezed by a robot.

108
00:05:22,000 --> 00:05:24,520
Speaker 1: You never know if if the thing's gonna go berserk

109
00:05:24,600 --> 00:05:26,880
Speaker 1: and just snap your arm right off. I think, yeah,

110
00:05:26,920 --> 00:05:28,680
Speaker 1: that's part of the fear, is that it will take

111
00:05:28,720 --> 00:05:31,800
Speaker 1: on a mind of its own and sever my arm off. Yeah. Yeah,

112
00:05:31,839 --> 00:05:36,000
Speaker 1: I think that's everybody's fear. So what about diastolic? That's

113
00:05:36,080 --> 00:05:38,440
Speaker 1: the bottom number, right uh, And I think for a

114
00:05:38,440 --> 00:05:42,760
Speaker 1: healthy adult eighties a good reading. Um so, the the

115
00:05:42,760 --> 00:05:45,600
Speaker 1: the good blood pressure reading, a very healthy blood pressure

116
00:05:45,600 --> 00:05:49,760
Speaker 1: reading is one eight. That bottom number represents what the

117
00:05:50,839 --> 00:05:56,400
Speaker 1: normal relaxing or relaxed pressure on a vessel, uh is

118
00:05:56,400 --> 00:05:59,040
Speaker 1: when the heart is at rest, when when the blood's

119
00:05:59,120 --> 00:06:01,359
Speaker 1: not being four wors through. It's just you know, the

120
00:06:01,400 --> 00:06:03,800
Speaker 1: hearts at rest blood vessels just sitting there like oh,

121
00:06:03,839 --> 00:06:06,280
Speaker 1: I'm waiting for the next pump, you know. Uh, so

122
00:06:06,400 --> 00:06:10,440
Speaker 1: eighties good? Um. And the thing is is those numbers

123
00:06:10,480 --> 00:06:12,920
Speaker 1: can change just a little bit and make some really

124
00:06:13,240 --> 00:06:14,880
Speaker 1: you know that it can be it can be really

125
00:06:14,920 --> 00:06:17,920
Speaker 1: bad with just a couple of numbers being off. Right. Well,

126
00:06:17,960 --> 00:06:20,320
Speaker 1: tell me more, Well, I will tell you more, Chuck.

127
00:06:20,400 --> 00:06:22,760
Speaker 1: Let me tell you about the third kind of pressure reading.

128
00:06:22,760 --> 00:06:26,960
Speaker 1: It's called pulse pressure. Uh. It's not uh necessarily widely

129
00:06:27,000 --> 00:06:30,880
Speaker 1: accepted yet, although it's really gaining traction. So pulse pressure

130
00:06:30,960 --> 00:06:34,760
Speaker 1: is just the difference between the systolic and diastolic pre

131
00:06:34,760 --> 00:06:37,840
Speaker 1: pressure readings. Right, So if one twenty over eighty is

132
00:06:38,080 --> 00:06:42,800
Speaker 1: optimal health for blood pressure reading, then forty would be

133
00:06:43,000 --> 00:06:46,480
Speaker 1: the optimal pulse pressure. It's the difference when eighty got you.

134
00:06:47,040 --> 00:06:49,400
Speaker 1: If it's uh, if it's a high, or if the

135
00:06:49,440 --> 00:06:53,000
Speaker 1: difference is high, uh, you've got problems. It can mean

136
00:06:53,040 --> 00:06:56,599
Speaker 1: that your your blood vessels are hardened, that they have

137
00:06:56,960 --> 00:07:00,039
Speaker 1: lost elasticity. There's there's all sorts of problems with it.

138
00:07:00,160 --> 00:07:02,680
Speaker 1: It can also mean that your heart is getting a

139
00:07:02,720 --> 00:07:06,560
Speaker 1: little too buff. Hypertrophy, all right, buff in this case

140
00:07:06,720 --> 00:07:09,120
Speaker 1: is not good. No, it's good for the bicep not

141
00:07:09,200 --> 00:07:11,960
Speaker 1: good for the heart because an overly buff heart can

142
00:07:12,040 --> 00:07:16,120
Speaker 1: can fail a lot more easily. Yeah, so we've got

143
00:07:16,120 --> 00:07:18,920
Speaker 1: the pulse pressure difference, and and I read that every

144
00:07:19,080 --> 00:07:24,960
Speaker 1: ten um millibars of mercury, which is the pressure reading difference,

145
00:07:25,440 --> 00:07:28,880
Speaker 1: actually increases your chance of stroke by like eleven percent.

146
00:07:29,480 --> 00:07:31,440
Speaker 1: So so it's important to keep an eye on your

147
00:07:31,440 --> 00:07:33,800
Speaker 1: blood pressure and and to keep an eye on whether

148
00:07:33,880 --> 00:07:39,239
Speaker 1: or not you're you're hypertensive or pre hypertensive. Um. And Uh, again,

149
00:07:39,400 --> 00:07:40,800
Speaker 1: the best way to find that out is to just

150
00:07:40,840 --> 00:07:44,280
Speaker 1: go visit your doctor regularly and get some blood pressure reading, right,

151
00:07:44,360 --> 00:07:47,960
Speaker 1: because hypertension a k A. High blood pressure. There's pre

152
00:07:48,120 --> 00:07:50,720
Speaker 1: high pertension, which you mentioned, which is before it's a

153
00:07:50,760 --> 00:07:53,200
Speaker 1: real problem, but it's when you can really correct it

154
00:07:53,240 --> 00:07:55,880
Speaker 1: with your diet and things like that. And then um,

155
00:07:56,160 --> 00:07:59,960
Speaker 1: secondary hypertension and hypertension or when things get out of hand,

156
00:08:00,040 --> 00:08:04,640
Speaker 1: when you're in danger of maybe a cardiac arrest or stroke. Uh.

157
00:08:04,680 --> 00:08:06,760
Speaker 1: And then the other thing I want to talk about,

158
00:08:06,760 --> 00:08:09,120
Speaker 1: which I thought was kind of interesting, was white coat hypertension.

159
00:08:09,280 --> 00:08:12,640
Speaker 1: Give it to me, this sounds interesting. Yeah, this is when, uh,

160
00:08:12,720 --> 00:08:15,360
Speaker 1: your your blood pressure actually elevates when you go to

161
00:08:15,400 --> 00:08:19,680
Speaker 1: the doctor. Oh, from from being nervous. I'm not sure

162
00:08:19,720 --> 00:08:21,520
Speaker 1: if it's from being nervous or not, but it's you

163
00:08:21,760 --> 00:08:24,040
Speaker 1: have a different blood pressure. White coat obviously it's what

164
00:08:24,040 --> 00:08:26,280
Speaker 1: the doctor wears and the doctor's office and you at home.

165
00:08:26,920 --> 00:08:29,600
Speaker 1: And I guess you know, my easy answer would be

166
00:08:29,600 --> 00:08:32,360
Speaker 1: don't come into doctor and you won't get high blood pressure.

167
00:08:32,360 --> 00:08:34,920
Speaker 1: But that's that's no good advice. And you should also

168
00:08:35,679 --> 00:08:39,880
Speaker 1: be wary of any doctor that doesn't wear a white coat, right, Yeah, yeah,

169
00:08:39,960 --> 00:08:42,600
Speaker 1: that's that's good advice too. That is interesting. They've also

170
00:08:42,640 --> 00:08:46,640
Speaker 1: found that um pregnant women can often demonstrate higher blood

171
00:08:46,640 --> 00:08:49,200
Speaker 1: pressure just because of their pregnancy as well. It can

172
00:08:49,400 --> 00:08:52,480
Speaker 1: be normal before the pregnancy, it can be high during

173
00:08:52,480 --> 00:08:54,760
Speaker 1: the pregnancy, and then go back to normal afterwards. To

174
00:08:55,600 --> 00:08:57,640
Speaker 1: the impression I got was that we didn't have a

175
00:08:57,679 --> 00:09:00,760
Speaker 1: really good read on exactly why that happens. We just

176
00:09:00,800 --> 00:09:03,920
Speaker 1: know it does happen, much like the white coat blood

177
00:09:03,920 --> 00:09:06,920
Speaker 1: pressure exactly. And uh, I've got some other stats for

178
00:09:06,960 --> 00:09:08,320
Speaker 1: you if you just want me to do. You know

179
00:09:08,440 --> 00:09:10,800
Speaker 1: how I feel about stats, Chuck, don't tease me, give

180
00:09:10,840 --> 00:09:14,000
Speaker 1: me to me. Well, uh, they did some studies on

181
00:09:14,480 --> 00:09:17,720
Speaker 1: percentage of adults twenty years over that have high pertension

182
00:09:18,240 --> 00:09:22,120
Speaker 1: or that are taking medication for hypertension. And overall thirty

183
00:09:22,160 --> 00:09:24,880
Speaker 1: percent of men and women are following into that category,

184
00:09:24,960 --> 00:09:27,120
Speaker 1: which really, yeah, which is more than I thought. Over

185
00:09:27,240 --> 00:09:29,679
Speaker 1: twenty I would think that the maybe a stat over

186
00:09:29,760 --> 00:09:32,840
Speaker 1: forty or fifth women come in and right at the

187
00:09:32,840 --> 00:09:35,199
Speaker 1: thirty percent mark. Men a little bit less believed or

188
00:09:35,240 --> 00:09:38,560
Speaker 1: not at pent and uh, the stat I thought was

189
00:09:38,600 --> 00:09:42,959
Speaker 1: interesting is that poor people are thirty at thirty four percent,

190
00:09:43,200 --> 00:09:45,840
Speaker 1: whereas non poor or twenty eight percent. Well, it makes

191
00:09:45,840 --> 00:09:48,679
Speaker 1: a lot of sense, you know. Um the uh, the

192
00:09:48,720 --> 00:09:53,559
Speaker 1: poor usually have less access to a healthy diet, right, Uh,

193
00:09:53,720 --> 00:09:56,080
Speaker 1: usually less time to eat well or take care of

194
00:09:56,080 --> 00:09:58,800
Speaker 1: themselves since they're working. Cheaper packaged foods and I are

195
00:09:58,840 --> 00:10:01,199
Speaker 1: loaded with sodium and podium and salt. It's a big

196
00:10:01,360 --> 00:10:03,400
Speaker 1: contributor to high blood pressure. So that kind of does

197
00:10:03,480 --> 00:10:05,240
Speaker 1: make sense. Well, Chuck, why don't you tell us some

198
00:10:05,480 --> 00:10:09,920
Speaker 1: ways that we can avoid hypertension? And if you have hypertension,

199
00:10:09,960 --> 00:10:12,920
Speaker 1: I mean, what can you do? Well? Uh? Kind of

200
00:10:12,920 --> 00:10:15,360
Speaker 1: like with everything else, the doctor tells you eat healthy,

201
00:10:15,679 --> 00:10:19,840
Speaker 1: lose weight, lay off the salt, limit alcohol, and quit smoking. Yeah,

202
00:10:19,880 --> 00:10:22,720
Speaker 1: and I looked into smoking. Uh, you know, it turns

203
00:10:22,720 --> 00:10:25,559
Speaker 1: out that smoking I thought it would stimulate the heart

204
00:10:25,679 --> 00:10:28,360
Speaker 1: and would wear it out faster. It turns out that

205
00:10:28,400 --> 00:10:32,640
Speaker 1: doesn't happen. Smoking actually goes in and injures your blood vessels.

206
00:10:32,640 --> 00:10:35,719
Speaker 1: That's how smoking can cause heart disease and hypertension, which

207
00:10:35,760 --> 00:10:38,040
Speaker 1: I found interesting. But yeah, you want to stay away

208
00:10:38,040 --> 00:10:41,240
Speaker 1: from the cigarettes, the cigars, any kind of smoking is

209
00:10:41,240 --> 00:10:43,000
Speaker 1: going to be bad for your heart, right, And as

210
00:10:43,000 --> 00:10:45,360
Speaker 1: far as your diet goes, they have something they recommend

211
00:10:45,360 --> 00:10:48,200
Speaker 1: called the DASH diet d A s H stands for

212
00:10:48,440 --> 00:10:52,959
Speaker 1: Dietary Approaches to Stopping Hypertension. And uh, what you want

213
00:10:52,960 --> 00:10:57,319
Speaker 1: to eat is whole grains, poultry, fish, nuts. You want

214
00:10:57,320 --> 00:11:00,719
Speaker 1: to limit fats and red meat. So not some much bacon, huh,

215
00:11:01,240 --> 00:11:04,800
Speaker 1: not as much bacon, steak, stuff like that. Yeah, it's

216
00:11:04,800 --> 00:11:06,920
Speaker 1: a nice it's a nice treat, but that shouldn't be

217
00:11:06,920 --> 00:11:10,360
Speaker 1: your regular, agreed, chuck. So what happens if you do

218
00:11:10,400 --> 00:11:12,760
Speaker 1: have hypertension? I mean obviously that there's a there's a

219
00:11:12,760 --> 00:11:15,240
Speaker 1: lot of medications out there in the market for people

220
00:11:15,280 --> 00:11:18,640
Speaker 1: who are hypertensive, right, Yeah, there's a lot of medications,

221
00:11:18,640 --> 00:11:20,360
Speaker 1: but a lot of these have side effects too, so

222
00:11:20,480 --> 00:11:22,719
Speaker 1: it depends on how higher blood pressure is as to

223
00:11:22,760 --> 00:11:24,400
Speaker 1: whether or not a doctor thinks it's worth it to

224
00:11:24,400 --> 00:11:27,920
Speaker 1: get on these meds um and potentially suffer some side effects.

225
00:11:27,920 --> 00:11:29,959
Speaker 1: So it's a few points here and there. They'll probably

226
00:11:29,960 --> 00:11:31,439
Speaker 1: recommend that you take care of it through diet and

227
00:11:31,480 --> 00:11:35,080
Speaker 1: exercise if you have a real problem. Um, there's all

228
00:11:35,160 --> 00:11:41,360
Speaker 1: kinds of anti hypertensive drugs, diuretics, uh, sympathetic inhibitors UH,

229
00:11:41,400 --> 00:11:45,959
Speaker 1: calcium channel inhibitors, a C inhibitors, and you know they'll

230
00:11:46,000 --> 00:11:51,920
Speaker 1: do a good job. But you know side effects like sedation, nightmares, depression, vertigo, uh,

231
00:11:52,080 --> 00:11:57,280
Speaker 1: stuff like that. The effects. Yeah, my favorite side effect death. Yeah.

232
00:11:57,720 --> 00:12:01,000
Speaker 1: I love it when they say that as pharmaceuticals. Well,

233
00:12:01,000 --> 00:12:04,520
Speaker 1: you mentioned sympathetic inhibitors. Is that that would have to

234
00:12:04,559 --> 00:12:08,200
Speaker 1: do with the sympathetic nervous system, right, Yeah, that would

235
00:12:08,200 --> 00:12:11,120
Speaker 1: control your fight or flight response correct, right, which is

236
00:12:11,160 --> 00:12:13,079
Speaker 1: something that we like to talk about under fight or

237
00:12:13,080 --> 00:12:16,680
Speaker 1: flight response. Well, if you do have hypertension and you

238
00:12:16,720 --> 00:12:19,880
Speaker 1: are being treated for it, take hope. I read somewhere

239
00:12:19,880 --> 00:12:24,720
Speaker 1: that six of people who suffer from hypertension recover from it.

240
00:12:24,800 --> 00:12:27,959
Speaker 1: They gain control of their blood pressure. It's goods. Go

241
00:12:28,120 --> 00:12:31,240
Speaker 1: see your doctor, eat well, quit smoking, watch the booze

242
00:12:31,240 --> 00:12:33,400
Speaker 1: all that, and Uh, if you want to learn a

243
00:12:33,400 --> 00:12:37,960
Speaker 1: lot more about hypertension, read hypertension in depth on how

244
00:12:38,000 --> 00:12:40,960
Speaker 1: stuff works dot com and stick around to find out

245
00:12:40,960 --> 00:12:43,120
Speaker 1: how Chuck and I know that the world about in

246
00:12:43,600 --> 00:12:47,120
Speaker 1: right after this stuff you should know is brought to

247
00:12:47,160 --> 00:12:49,560
Speaker 1: you by Visa. We all have things to think about,

248
00:12:49,920 --> 00:12:51,679
Speaker 1: like say, what's the best sight to buy a new

249
00:12:51,760 --> 00:12:54,320
Speaker 1: leather jacket, or whether to buy the three or six

250
00:12:54,400 --> 00:12:57,640
Speaker 1: megapixel camera. But thankfully we don't need to think about

251
00:12:57,640 --> 00:13:01,160
Speaker 1: online fraud because for every purchase you make, Visa keeps

252
00:13:01,160 --> 00:13:04,239
Speaker 1: an eye out for fraud with real time fraud monitoring

253
00:13:04,679 --> 00:13:07,960
Speaker 1: and by making sure you're not liable for any unauthorized purchases.

254
00:13:08,280 --> 00:13:15,240
Speaker 1: How's that for peace of mind? Safe? Secure Visa so check.

255
00:13:15,280 --> 00:13:17,000
Speaker 1: You want to tell everybody how we're privy to the

256
00:13:17,040 --> 00:13:19,760
Speaker 1: information that the world's about to end, well, Josh, is

257
00:13:19,760 --> 00:13:24,080
Speaker 1: not because we're smarter than everyone else, because that's not true. Uh,

258
00:13:24,080 --> 00:13:26,080
Speaker 1: it's because we read the article. Are frogs on the

259
00:13:26,080 --> 00:13:29,400
Speaker 1: brink of extinction? That's true. Frogs are an indicator species,

260
00:13:29,400 --> 00:13:31,680
Speaker 1: and when they start disappearing, everybody else at the top

261
00:13:31,679 --> 00:13:34,600
Speaker 1: of the food chains in big, big trouble. So this

262
00:13:34,640 --> 00:13:36,760
Speaker 1: is something you might want to do a little research on.

263
00:13:36,840 --> 00:13:39,400
