Speaker 1: Welcome to Stuff from the Science Lab from how stuff
Speaker 1: works dot com. So, Robert, yeah, what is an astronomical unit.
Speaker 1: I don't know what astronomical unit. It's one hell of
Speaker 1: a big apartment. Oh, welcome to the podcast guys. This
Speaker 1: is Alice and the science editor at how storks dot com.
Speaker 1: And this is Robert Lamb, of science writer at how
Speaker 1: stuff works dot com. And that comes to you from
Speaker 1: Bruno in Switzerland. We've been putting the call out for
Speaker 1: jokes lately on faceboo. Nice cheesy science related jokes. There's
Speaker 1: no reason that scientists can't be humorous, and there's no
Speaker 1: reason that scientists can't smell fabulous, right, right, right, So
Speaker 1: today we're talking about the science of perfume, and I
Speaker 1: wanted to talk a little bit about the worst smell
Speaker 1: that you like, you know, sort of the smell you're
Speaker 1: not supposed to like, but you do. Um. For me,
Speaker 1: it's it's kind of weird cont that, but go on, well,
Speaker 1: you know, you know it smells bad for you're not
Speaker 1: supposed to be sniffing it. You know, I'm not talking
Speaker 1: about you know, sniffing something to get you know, an effect,
Speaker 1: but just you kind of like the smell of it,
Speaker 1: like gasoline is mine. Okay, It's like I'm not talking
Speaker 1: about huffing, but gasoline smells fabulous. But I do like
Speaker 1: it also on that vein rubber cement. Okay, okay, but
Speaker 1: that's perfect sense. Wait what's yours? Um Well, I mean
Speaker 1: I'm one of these people I tend not to think
Speaker 1: of like smells. I like is being like horrible. Um well,
Speaker 1: like one example, okay, during fruit kind of gets a
Speaker 1: bad rap for being a dozen indeed, have you ever
Speaker 1: eaten one? But yeah, that's the thing. It's like I
Speaker 1: finally got to try it when my wife and I
Speaker 1: went to Thailand and and Grant, we were outdoors in
Speaker 1: a we're well ventilated area and okay, everybody's just like
Speaker 1: our daurian fruit. The smells horrible, blah blah blah. I
Speaker 1: mean not the people have sold it to us, obviously,
Speaker 1: but but you know, you hear that especially here in
Speaker 1: the States, and um and I really wanted to try
Speaker 1: it and give it a fair shape because I'm kind
Speaker 1: of thinking like this kind of like Western you know, chauvitism.
Speaker 1: It's like, you know, saying I don't want this fruit.
Speaker 1: You're an equal opportunity for you. So I gave it
Speaker 1: a shot and it was it was really good. I mean,
Speaker 1: it's I think the thing with the Durian fruit is
Speaker 1: that you kind of have to go into it expecting
Speaker 1: more of a cheese like it's some sort of a
Speaker 1: cheese fruit kind of a thing. But really, yeah, but
Speaker 1: in terms of things that, like, I guess I do
Speaker 1: have to admit that I now remember that like sometimes
Speaker 1: like when I'm painting, like painting, like house painting and
Speaker 1: stuff like, there is something kind of nice about that smell,
Speaker 1: like it almost kind of smells chocolate somehow to me,
Speaker 1: like I should eat it. Yeah. Well, I think it
Speaker 1: also has to do with a texture of the paint
Speaker 1: a little bit. You know, it has that like thickness
Speaker 1: when it's going on. And and I guess we do
Speaker 1: tend to paint like the painting jobs I've been on,
Speaker 1: it tends to be kind of like a brownish or
Speaker 1: a tannish you know, or like even like a white
Speaker 1: chocolate kind of color. Stuff. Okay, Well, technically that could
Speaker 1: be a perfume, because perfume is a pretty I mean,
Speaker 1: you can define pretty much anything as a perfume. It's
Speaker 1: a pretty loose definition. It's basically something that you wear
Speaker 1: and something that smells. I mean, I'm sure the professional
Speaker 1: perfumers out there I have a more rigorous definition. But
Speaker 1: for our purposes, like you don't count like Irish spring
Speaker 1: is a perfume, but it doesn't necessarily have to smell
Speaker 1: good or good to everyone. Right, Definitely baste on some
Speaker 1: of the perfumes I've smelt on public transportation, Yeah, no doubt.
Speaker 1: So for our purposes, let's talk about liquid perfume. You know,
Speaker 1: the stuff you're gonna find in a bottle um, you know,
Speaker 1: a sprayer spitzer um, and that's just going to be
Speaker 1: a combo of alcohol, water and whatever key ingredients that
Speaker 1: evaporated room temperature that you you know, want to throw
Speaker 1: in to make your signature fragrance. And when you're smelling perfume,
Speaker 1: you're really just sniffering a bunch of evaporating molecules. Right.
Speaker 1: Your nose detects perfume and it sends a message. Shear
Speaker 1: brain creating this perception good, bad, and different, whatever it
Speaker 1: may be. And you know that's what's going on in
Speaker 1: the elevator. Have you ever had this experience, I know
Speaker 1: all of you listeners. Definitely. Have you walk into the elevator,
Speaker 1: you know, somebody gets on at the next floor. They
Speaker 1: walk in in with them trills this just ragrant cloud
Speaker 1: of cologne or perfume. And I won't say it's women
Speaker 1: or ladies or men, because you know, I think both
Speaker 1: definitely do this. Like there was this one dude that
Speaker 1: I used to work with him in a before it
Speaker 1: came to hou stuff works, and it's like I remember
Speaker 1: the day he came in to apply for his job.
Speaker 1: It was like, you know that comes in through the door.
Speaker 1: It's just this stream of just just really strong like
Speaker 1: cologne was just hanging off of him. And then he
Speaker 1: left and like the cologne stayed. I think that's when
Speaker 1: he gave him the job. It's like it's gonna smell impression.
Speaker 1: Yeah he did that man made an impression. Yeah. When
Speaker 1: I was in college, is reminded me a lot of
Speaker 1: Thursday nights. To me, you'd be going out and you
Speaker 1: get in a you get an elevator with a with
Speaker 1: a boy and he would just you know, the whole
Speaker 1: elevator would smell like dre card noir. Do you remember
Speaker 1: that cologne? I think I remember. I think maybe my
Speaker 1: dad had an old bottle of it, and I like
Speaker 1: found it somewhere and it's like dark looking, right, it's
Speaker 1: like dark manly looking cologne, I think. So, like, the
Speaker 1: more it looks like whiskey, the more it's okay for
Speaker 1: guys to wear it. Yeah, if I sniffed it now
Speaker 1: would totally take me back. So what's going on with
Speaker 1: the individual ingredients in those perfumes, like what's making the
Speaker 1: car or linger so long? Well, my understanding is that
Speaker 1: the alcohol works to spread out the different smells, right,
Speaker 1: allowing you to to to pick up the different hints
Speaker 1: and the complexities of the perfume. Otherwise you'd be small
Speaker 1: on them all at once, right, right. So, writer Susan Nasa,
Speaker 1: who wrote the article on our site about how how
Speaker 1: perfume works, was talking about in the in the case
Speaker 1: of a perfume oil, Um, if you were just to
Speaker 1: smell that perfume oil, which is a really concentrated essence
Speaker 1: of the smell, it would kind of be like hearing
Speaker 1: all the members of an orchestra all play at the
Speaker 1: same time. Yeah, you're not going to hear the you know,
Speaker 1: the tuba kind of rumbling. Um. So that that's that's
Speaker 1: a perfemale. But the alcohol, right, it allows you to
Speaker 1: hear or smell, as the case maybe with perfume, all
Speaker 1: these notes um not at once. It spreads them out
Speaker 1: like you said, Okay, It's kind of like if you
Speaker 1: go to Tapas restaurant and like they bring out you know,
Speaker 1: topless restaurant where it and it's, uh, you don't want
Speaker 1: all the top as at once in gobl them down
Speaker 1: in or you want to be there for like a
Speaker 1: lengthy period of time getting the one by one definitely, definitely.
Speaker 1: So in that same vein, it makes sense that a
Speaker 1: lot of perfumes and when we're talking about perfumes again,
Speaker 1: perfume does not applied to women or men. It's just
Speaker 1: it's like we said, a smell um so they have
Speaker 1: a three part smell and each smell is called a
Speaker 1: note in the perfume industry, and that's what they like
Speaker 1: to come. But it's just jargon, and I was not
Speaker 1: familiar with this at all before we research this. It's
Speaker 1: pretty cool, and the smells have different rates of evaporation,
Speaker 1: so on the top you're gonna have your top note, right,
Speaker 1: and uh, you're gonna smell these within fifteen minutes of apply.
Speaker 1: This is where you're gonna find kind of the racy, unpleasant, spicy,
Speaker 1: weird smell, you know, something that the designer threw into
Speaker 1: just kind of you know, be crazy. This is the
Speaker 1: don't apply your perfume on on the train smell, right
Speaker 1: when the person next you decides to put it on
Speaker 1: and you're like cheese and that that's this. This is
Speaker 1: the top These are the top notes in action, right yeah. Yeah,
Speaker 1: And and and these are the ones, luckily, that evaporate first.
Speaker 1: So take us to the take us through the heart notes.
Speaker 1: All right, Well, this apparently starts showing up after three
Speaker 1: to four hours after you've gotten off the train, ideally
Speaker 1: hanging out at work, and these evaporate more slowly from
Speaker 1: the skin. The phase of the perfume's life tends to
Speaker 1: be what this is the This is the phase that
Speaker 1: makes the most impact. This is what you remember. This
Speaker 1: is the prime perfume life stage, right, Robert, if you
Speaker 1: were wearing a floral perfume, do you wear a floral perfume? Okay,
Speaker 1: So this is where you find your floral notes, okay, okay,
Speaker 1: and then you get your base notes, right, and so
Speaker 1: these form obviously the foundation of the perfume, the base
Speaker 1: of the perfume, and they linger the longest after you
Speaker 1: douse yourself in the morning, the five to eight hours
Speaker 1: long in a fact. And it's not just the chemistry
Speaker 1: of the perfume and you know the rate of the
Speaker 1: molecules evaporating, it's you're a factor to right, So the
Speaker 1: top notes of the perfume are going to disappear faster
Speaker 1: if your skin is nice and dry and warm, um,
Speaker 1: rather than if you're kind of cool and oily. So
Speaker 1: you're gonna so when you go shopping for a perfume,
Speaker 1: you need to sort of carry some of the information
Speaker 1: with you, like, no, am, I you know, but how
Speaker 1: my skin is going to behave with it? Sure? I mean,
Speaker 1: I guess I wouldn't hurt to keep that in mind.
Speaker 1: And then how you store the perfume is going to
Speaker 1: affect the chemistry as well. If you store it in
Speaker 1: bright light, that can impact the bonds and the freegrance
Speaker 1: molecules and break them um, and then you're you can
Speaker 1: have bright sun that canna damaged perfume within a week's time.
Speaker 1: And that was according to a Luca Turan Antonia Sanchez,
Speaker 1: authors of the two thousand and eight book Perfume A Guide. Uh,
Speaker 1: that's the one for the dude Kills All the Ladies, right, No,
Speaker 1: that's fiction by Patrick Suskin. Yeah. Yeah, the protagonist of that.
Speaker 1: What is he he's trying to he's trying to. I've
Speaker 1: seen the movie, I've not read the book. Read Okay,
Speaker 1: well we complete each other and that then like, um,
Speaker 1: he I remember correctly, he wants to, like he like
Speaker 1: falls for these different ladies and like he finds them
Speaker 1: into a into perfume. Right, he wants to According to Amazon,
Speaker 1: I believe captured the scent of a beautiful young version.
Speaker 1: That's it. That's what he's trying to do. And by
Speaker 1: version I meant virgin. Yeah. Um, but if it's sort
Speaker 1: of like Silence of the Lambs but with perfume, what
Speaker 1: do you think about that? Yeah? Pretty pretty good. The
Speaker 1: movie was pretty fabulous, pretty really Yeah, it had Dustin
Speaker 1: Hoffman and it's a perfumest in it. But but back
Speaker 1: to the storage. Think, what's weird to me about the
Speaker 1: whole visible light breaking it down? It's like most perfumes
Speaker 1: come in like a little glass vials, right, I mean
Speaker 1: it's true, it's just begging to be broken down by
Speaker 1: the sun, and they're begging to be displayed, right, I
Speaker 1: mean because packaging, of course is such a big part
Speaker 1: of perfume as well. Well, that goes into another podcast
Speaker 1: that we did on the Smell and Science. Yeah, we've
Speaker 1: been on a smelly bender this week. Well, there's a
Speaker 1: whole deal about how, like how you know, the information
Speaker 1: from our other senses also affect how we perceive a smell.
Speaker 1: If you tell me that a cheese is cheese, then
Speaker 1: I'm gonna respond better than if you tell me a
Speaker 1: cheese is body odor and and likewise in general, that's it.
Speaker 1: That's a good assumption. Yeah, But the thing is, it's
Speaker 1: like they say that it also ends up applying to
Speaker 1: like the shape of our perfume container or the like
Speaker 1: the different the name or you know what are all
Speaker 1: these different factors that they're using to sell it to you.
Speaker 1: It's like that you shape it like an apple, even
Speaker 1: if it doesn't quite smell like an apple. It's like
Speaker 1: you're gonna be more inclined to think apple when you
Speaker 1: when you sniff it. Right, So smell being much more
Speaker 1: than just the physical act of sniffing. Yeah, So before
Speaker 1: we move on. I just wanted to touch on. There's
Speaker 1: one other process that can can harm your perfume, and
Speaker 1: you guys know this is oxidation. So this is what's
Speaker 1: going to turn your uncorked wine into vinegar. And it
Speaker 1: can do a number on your bottle of Chanel number
Speaker 1: five as well. Okay, So don't keep your perfume out
Speaker 1: in a like trough on your on your desk. Yeah,
Speaker 1: and storing your perfume at room temperature in the dark
Speaker 1: and in a spray bottle preserves it well, maybe a
Speaker 1: shelf life of two years, which is interesting because I
Speaker 1: think I tend to keep my sons much longer than
Speaker 1: two years. To self, Okay, I gotta go home and
Speaker 1: clear out the perfumes pomode on the sink. No, I
Speaker 1: will not do that. So why do we wear perfume?
Speaker 1: I found this pretty interesting? Um So, the writer Susan
Speaker 1: Nasser interviewed this psychologist, Rachel Hurts Uh and she's a
Speaker 1: she's a Brown University and she's researched smell pretty extensively.
Speaker 1: It Hurts had a couple of ideas about why people
Speaker 1: wear these scents. You want to take the men ones? Yeah,
Speaker 1: and this this makes a you know a lot of sense,
Speaker 1: like young men wear fragrance to attract women or four men. Um,
Speaker 1: you know what a preference and uh, of course that
Speaker 1: makes perfect sense. And that's like the stereotype too. You know.
Speaker 1: It's like guys putting on some sort of funky scent
Speaker 1: generally and on oftentimes maybe not generally, but often not
Speaker 1: knowing quite what they're doing when when they're picking one out. Um.
Speaker 1: So that's the young guys and then the older men.
Speaker 1: According uh, according to Nasser, older men wear it as
Speaker 1: a nod to the person who gave them the perfume.
Speaker 1: In other words, I'm wearing this perfume because i got
Speaker 1: it as a gift and I've got to use the
Speaker 1: whole bottle where I'm never going to hear the end
Speaker 1: of it. And I think you and I think you
Speaker 1: think it smells nice. So yeah, so I guess as
Speaker 1: well as nice, I'll wear it. If she likes it, well,
Speaker 1: we're going out to dinner, might as well. That was
Speaker 1: myself a little bit. Yeah, generally I don't receive perfumes
Speaker 1: except from um. Bonnie's grandmother gave me perfume one year. Yeah,
Speaker 1: I think we quietly destroyed it. I hope she's not listening.
Speaker 1: Um So, young women may wear it because of friends,
Speaker 1: uh and and media influence. This one actually rang true
Speaker 1: for me. I remember at a certain point in my
Speaker 1: life in middle school, I think I did start to
Speaker 1: wear fragrance. And it wasn't because I you know, wait,
Speaker 1: you probably were, didn't you like wear it earlier? Like
Speaker 1: you went and like trying on all your mom's perfume
Speaker 1: at once? Yeah, that's probably true. I probably did. But
Speaker 1: you know, I actually bought a bottle from my local
Speaker 1: drug store or something like baby Softer, I don't even know,
Speaker 1: some terrible perfume. Not that it's terrible, but I just
Speaker 1: probably wouldn't buy it now. But it was very much
Speaker 1: something that all my friends were doing, so it was
Speaker 1: more like in you know, a reflection of growing up
Speaker 1: or something to that effect. Um So, her is the
Speaker 1: psychologists that that a writer interviewed says that women in
Speaker 1: thirties do it just because you know, they want to. Uh,
Speaker 1: once you get into your forties, they're wearing it because
Speaker 1: they like it. This sounds random to me, though, I mean,
Speaker 1: you don't like it before and then well, I mean
Speaker 1: maybe it's kind of like with you know, some people
Speaker 1: steal with like say beer, you kind of like, you
Speaker 1: drink beer tastes horrible at first, and then supposedly if
Speaker 1: you drink enough of it, you start to love it
Speaker 1: and then you like it takes a while to like
Speaker 1: build up in appreciation for it. So maybe it's like
Speaker 1: you spend your thirties, you know, using these perfumes, but
Speaker 1: you don't really necessarily like it, but you know, after
Speaker 1: a while, then you develop this real appreciation for it
Speaker 1: and then you're, you know, totally into it. That being
Speaker 1: the case. By sixty again, the women are just wearing
Speaker 1: it to please others. Well maybe they're just they're just
Speaker 1: nice old ladies and they're like, I'm just gonna gonna
Speaker 1: wear this because my son credit for me and they'll
Speaker 1: make them happy. Kind of a deal, you know, right,
Speaker 1: righties are just nice, That's what saying. So sense can
Speaker 1: affect our moods and our behavior, right, we know this.
Speaker 1: I mean, it can pull up some sort of treasured
Speaker 1: memory and it can influence our actions. And there have
Speaker 1: been a couple of interesting studies in this vein um.
Speaker 1: I think that you guys have probably heard of the
Speaker 1: one about the cinnabon. Have you heard about that. We
Speaker 1: were talking about this a little bit before the podcast. Yeah,
Speaker 1: what was to do with this again? It's just the
Speaker 1: scent of cinamon, right, So put the put the scent
Speaker 1: of cinnabon in the air, do it, you know, in
Speaker 1: a mall. Okay, And what you're gonna want to do
Speaker 1: is you're gonna get some people involved. You're gonna get
Speaker 1: your participants, and you get one person to drop something
Speaker 1: and then, um, see if a stranger picks up that pencil,
Speaker 1: say that you dropped. Well, it turns out if you
Speaker 1: have the smell of cinnamon in the air, um, people
Speaker 1: are more likely to pick up that pencil. The stranger
Speaker 1: is more likely to pick up that pencil. Good smells
Speaker 1: as a correlation with you know, good behavior. You know
Speaker 1: you're going to pick up a pencil, maybe you'll give directions,
Speaker 1: maybe you're just going to be an all around nice
Speaker 1: person as long as you're within cinnabons. Wow, it's kind
Speaker 1: of interesting, it can. It makes me think of like
Speaker 1: a futuristic society, you know, where everybody is like a
Speaker 1: perfect citizen and they're doing it because they're just constantly
Speaker 1: pumping out the odor of cinnamon. You know what this
Speaker 1: really made me wonder, and I didn't have time enough
Speaker 1: to get into it before the podcast, was what do
Speaker 1: casinos smell like? I'm not a hardcore gambler, but I
Speaker 1: had to wonder how this sadness, stale cigarettes, sadness and
Speaker 1: cinnabone old ladies playing the slats. I don't know, that's
Speaker 1: really I'm gonna I'm very curious. Now. So there's a
Speaker 1: study in France that followed a sort of similar cinnamon protocol,
Speaker 1: only they check to see whether a woman who was
Speaker 1: wearing perfume would um influenced this sort of similar behavior
Speaker 1: and strangers so um, you know, she would drop something
Speaker 1: from her person, she would. They would see if strangers
Speaker 1: would help her pick up the object, and in fact
Speaker 1: they did. You know, the woman wearing the perfume brought
Speaker 1: out that behavior again she's smelt like cinnamon. No, she
Speaker 1: smelt like a different perfume. No they did not. Well,
Speaker 1: see they should combine these two studies, right, maybe they
Speaker 1: have them. It has the best I act if it's
Speaker 1: a cinnamon for fume. And then there's just one final
Speaker 1: study that I'll get you here. There's a study published
Speaker 1: in the Journal of Psychological Science, and that found that
Speaker 1: a citrus scented cleanser was associated with people behaving more
Speaker 1: fairly when they played a game, a classic trust game.
Speaker 1: According to this article on the Boston Globe, like apples
Speaker 1: to app sir, what I don't know, I don't know
Speaker 1: what the game was. Yeah, so fair behavior, people picking
Speaker 1: up pencils for you. I mean, it does seem like
Speaker 1: scent can influence action. And and that's just you know,
Speaker 1: a smattering of studies that have been done there. There
Speaker 1: are many more to explore. But let's let's take a
Speaker 1: break from that and look at the genetic side. So
Speaker 1: each of us has a genetically determined number of odor
Speaker 1: receptors or cells in our nose that grab fragrant molecules
Speaker 1: out of the air around us. So, with more receptors
Speaker 1: for a classic compounds like say lily smells, you're gonna
Speaker 1: smell lily at a lower concentration, but at normal amounts
Speaker 1: the smell could be intense and overwhelming. Alright, But too
Speaker 1: few receptors can be a problem. Why is that? Well,
Speaker 1: for example, cilantros fragrance consists of many odors. If your
Speaker 1: genetic code spells out of variation that reduces your number
Speaker 1: of receptors for an odor. You may miss one of
Speaker 1: Cilantro's many odors and it may smell soapy to you.
Speaker 1: We've got touched on this before, Yeah, we did on
Speaker 1: the genetic stuff. They're talking about it tasting soapy and
Speaker 1: of course sent and taste or blood brothers. Indeed, So
Speaker 1: let's get to the evolution side. And one question that
Speaker 1: people have thrown out a lot are you know, are
Speaker 1: our old factory likes and dislikes programmed? And there's pretty
Speaker 1: healthy argument on this area. So on the pro side,
Speaker 1: some people are going to argue that the answer as
Speaker 1: to whether we like certain smells isn't really genes but history, right, um,
Speaker 1: and you know, way way way back history like Grays,
Speaker 1: like just foraging for food kind of things like like
Speaker 1: I smell fruit, I eat fruit, fruits great. I wish
Speaker 1: everything smells like fruit. Is the center bund thing again?
Speaker 1: Yeah totally um, yeah, right, so that kind of harkens
Speaker 1: back to our foraging days are hunting and gathering days.
Speaker 1: And then you know, on the other hand, we're not
Speaker 1: gonna like the smell of you know, urine feces or
Speaker 1: you know, maybe rotten or fishy smells, because like urine
Speaker 1: could like it could be telling me that somebody else's territory, um,
Speaker 1: you know, fecal all that's gonna potentially parasites and pathogens
Speaker 1: two sees infectious agents, right, So there could there be
Speaker 1: an evolutionary mechanism at work there. That's that's one thought
Speaker 1: school of thought on this. I'm I'm game to believe that.
Speaker 1: What about the other side of the argument, Well, yeah,
Speaker 1: there's the other side of the argument says it smells
Speaker 1: are an evolutionary programmed and this is this is kind
Speaker 1: of like the sort of short, short and dirty version
Speaker 1: of this is like people can get used to anything, right,
Speaker 1: Your culture preference, your personal experience can override any smell.
Speaker 1: I mean, if you grow up with the latter and smell,
Speaker 1: maybe it's not going to bother you. Yeah, you grow up,
Speaker 1: you know, gutting fish, then the fish smell is not
Speaker 1: going to bother you. Back before the days of refrigeration,
Speaker 1: um now, Sir writes in her article, the smell of
Speaker 1: rotten meat was tolerated and even liked in Europe. Huh yeah,
Speaker 1: I guess I just don't really have a perception of
Speaker 1: rotten hamburger meat per se, just because the refrigerator does
Speaker 1: play such an important role. Well, one example that comes
Speaker 1: to mind, it's like I don't know if you know here,
Speaker 1: go to like like sort of foreign or not even foreign,
Speaker 1: but just kind of like I guess, like sort of
Speaker 1: Asian like kind of like fish markets and stuff, or
Speaker 1: I guess just any fish market. It's like, I'm not
Speaker 1: around them, so when I go to them, it's it's
Speaker 1: a bit overpowering. But I'm thinking, like people a people
Speaker 1: were around it a lot are going to be more
Speaker 1: less inclined to think it's stinky. And also if it's
Speaker 1: like more like a cultural thing, you're going to tolerate
Speaker 1: it more. Yeah, or maybe even you know, say you're
Speaker 1: a smoker, right, you know how smokers can smell themselves,
Speaker 1: but if you walk into an elevator with a smoker,
Speaker 1: you can instantly smell it. Or if you're riding the
Speaker 1: train with somebody who you know, hit happy hour, maybe
Speaker 1: they can't smell the alcohol on them, but I mean
Speaker 1: it just waffs over to you on a giant cloud
Speaker 1: of dirty martini. Yeah. Yeah, So anyway, So so that's
Speaker 1: really the other side of the argument is that, Yeah,
Speaker 1: like you were saying, we can override any of these preferences,
Speaker 1: and evolution really doesn't have a whole lot to do
Speaker 1: with smell. So I think we gave you guys a
Speaker 1: lot of odor for thought. Yeah, I mean, I'm I
Speaker 1: think it's. Yeah, next time you're throwing a little perfume,
Speaker 1: you might think about it a little differently you and
Speaker 1: also like maybe even like go ahead and mark down
Speaker 1: on your schedule, like which phase of the perfume is
Speaker 1: gonna is gonna line up with what part of your day.
Speaker 1: It's like, oh, crap, I got a three o'clock um,
Speaker 1: you know, interview, and that's after phase two ends. What
Speaker 1: am I gonna do about my floral notes being gone? Yeah?
Speaker 1: So we love to hear from you guys, smelly thoughts
Speaker 1: or otherwise. So send us an email at science Stuff
Speaker 1: at how stuff woraks dot com, or connect with us
