[Music] welcome to another episode of the scishow talk show today we are joined by clinical sexologist and host of sexplanations lindsey doe hi you know all about sex and anatomy and how life works incorrect I know some of a lot of it but not all of it okay I try though and it's fascinating so I like studying and learning more okay do you think you have a way to just dump me I have a question that I asked my students at the University which I would love to run by you and see if you would miss a point or not on my exam okay and that was okay can someone contract aids from having sex one time with one person who is who has AIDS yeah stumped what you're stumped because you can't contract aids you contract HIV trick questioned me so in the time period that we have known about the virus it has changed names a lot and it's also changed the number of stages and how we define those stages aids being the final stage so if I had a type of virus that created the symptoms of puking and nausea and fever chills etc and I sneezed on you mm-hmm I'm not giving you puking right I'm giving you whatever that virus is so the same thing goes with HIV and AIDS if I have AIDS and we were to engage in some sort of risk behavior such as sharing injection drug unprotected intercourse or breastfeeding or if we were to get in a car cache you I will make sure to not do any of those things with you thank you any any sort of blood seminal fluid fluid or breast milk exchange then I am NOT infecting you or putting you at risk for AIDS I'm putting you at risk for HIV and then whether or not that transforms into AIDS or manifests as AIDS really depends on what you're exposed to you and how the virus lives in your body hmm so HIV stands for human immunodeficiency virus and aids stands for acquired immunodeficiency syndrome so the syndrome is the set of symptoms correct basically interesting and we named it that because we weren't quite sure what the heck was going on when we first started to identify that correct yeah that was terrifying time it was people walking this probably won't remember that now I am the same age as our knowing of the virus but it is believed that it existed even prior to 1981 and it wasn't until we had somewhat homogeneous group being infected at the same time with the same symptoms that we are able to go in and say oh wow maybe this isn't actually pneumonia or tuberculosis but maybe there is another cause that is creating mm-hmm what is now pandemic so what what is that process of going from being infected with a virus to having AIDS all right so at the beginning you have a point of infection where the person has come in contact with the virus and if their body receives it it will attack the immune system which is the part that is actually designed to protect their body against viruses so when I teach people about HIV and I have my PowerPoint set up there is a little virus a sphere with knobs on the end of it and it has these arms that should be all muscular and wonderful but they're actually saggy and droopy because it's meant to demonstrate how weak this virus is it really needs its host in order to survive and it also has I'm Stein hair so I've the squiggly gray mass above the sphere to talk about how intelligent this virus is that it is going to attack the exact part of the body that is meant to fight it so here in Missoula we have the Grizzlies our main opponent as the Bobcats in Bozeman and in this analogy it would be like the Bobcats the virus coming over to our grizzly quarterback stripping it down dressing it up in Bobcat jockstrap jersey helmet mouth guard and those bands that they wear on their wrists with the game plays and then now you have the Grizzly quarterback operating with the Bobcat agenda so it's it's a brilliant virus all right so now we've got point of infection and then after this there's a fair amount of time sometimes even 20 years and beyond that this person could be asymptomatic where they're not expressing any symptoms experiencing any symptoms for a very long time so if they're not getting any feedback from their body that something is wrong they might not get tested and they might continue to infect other people and then after that period an AIDS diagnosis is made when there are 200 or less what are called cd4 or T cells in a microliter of collected fluid and that's when your immune system or the score of the Grizzlies has completely dropped at that point or if they have been if they've acquired a disease that the person otherwise wouldn't get mm-hmm they're healthy so there there are two two criteria mm-hmm that either one would give would qualify you as having AIDS yes but they're not they have nothing to do with whether or not you have the virus it's symptoms it's if you've acquired a disease that you would not otherwise have or if you have less than 200 cd4 T cells per microliter of blood that's crazy that's just like that's just an analytical test it's not you know it's not it's not actually like it's just a threshold that is defined by us as this is AIDS I would not have thought that things that I am surprised I didn't know I'm here to eat with Lindsey doe so this is fascinating but I think that we need to an uplift yeah this is going sexy she's going to come in the form of a chinchilla what me ash the chinchilla hi ash that scintilla ash is very uplifting cause he's SuperDuper cute you are super cute you're like 90% head I would like you guys to feel him do you want to touch him you're correct is it actually the softest I don't know thing I know my animals and this is the softest animal in the world in close competition with the sea otter but these guys the reason that they're soft is because of this hair obviously but they have 80 hairs per follicle what so to put that in comparison if we look at our arm we have little pores all over our skin right we have one hair per follicle per poor he has eighty hairs for every single follicle I have not even thought that that was a thing that could happen to have more than one hair before follicle and the idea that you could have 8080 and probably have way more follicles than we do he has tons of all those and I'm not sure the exact count of follicles but yes you have a lot of hairs it's impressive that billion is so dense and he so he's gonna use this fur to keep warm and there's a couple things about this for though that if he he does not want to get wet it's very difficult for him to dry off because he has such thick dense fur so instead of bathing in water he's gonna groom himself with his mouth a little bit but instead of bathing in water he's gonna bathe in volcanic ash into the name - so what he's gonna do is it's very very fine dust - and he's going to roll around on his back and squiggle and squirm and make this big dust storm and he's going to get that dust in between each one of those hairs making it separating them and coating them and making them so they won't clump together and that's what's gonna keep him clean and extra furry and fluffy and it's going to make sure that he doesn't get too cold now it's easy for him to overheat so he's going to use his ears to help him temperature regulate some heat yes he was not much fur on those ears and actually if you look closer you can see the blood vessels in those ears so no consent I'm sorry so he's gonna use those years to temperature regulate because he's gonna put them up away from his body and try and catch a breeze so it's gonna cool down the blood in those ears which is then going to circulate through his body and cool down his whole body all right so these guys some cool fun facts about them they're crepuscular did you know that means crepuscular that's like like blood vessels hmm no corpuscles that's another thing no no crepuscular is about when they're awake okay what time of day so we have Dyer and only of nocturnal and then randomly corpuscular is the other name for it in between those two sunset and Sun Rise that's when these guys are gonna be most active and they're gonna be running around up in the mountains up there and they have really big back legs you can't they look like a big ball of fur but actually if you can there's an indent right here and you can see that there they have a knee bone these guys can jump about three or four feet in the air good springers they use this here's this tail to help keep their balance as they're running and jumping through the their terrain there and that's going to help them run really fast and not fall down and slip they're gonna be running away from things that are also corpuscular like different kinds of wild dogs or holes we're gonna go ahead and let him go back and okay he's got to go cool off thanks for bringing bringing us back up and thanks for ashin Jesse thank you for having us and Lindsay also thank you for for joining us on scishow talk show and if you want to keep
