  • Why do we find other people's saliva so gross?

  • We each produce about two bathtubs

  • full of the stuff every year,

  • so why do we freak out when

  • even one drop of someone else's saliva

  • comes near us?

  • Getting the odd splash of saliva

  • from a "spitty talker" isn't going to kill you, but

  • what if you were submerged

  • in a large volume of it?

  • What kind of dangers

  • would you be exposed to?

  • The average-sized swimming pool in America

  • has a volume of about

  • 51,000 liters (13,000 gallons.)

  • If you were to try and fill this pool

  • with just your own spit,

  • it would take you about 93 years,

  • since you only produce about 1.5 liters a day.

  • So you would need some other people

  • to help you out and by some people,

  • we mean thousands of them continuously

  • spitting into the pool at the same time.

  • But even with all these people,

  • it would still take a long time to produce

  • enough saliva to fill an entire pool.

  • So is there anything else we could do

  • to speed up the process?

  • And would you really want to dive in

  • once it was filled?

  • Okay, so let's say you're getting really impatient

  • as you wait for your volunteers to fill up this pool.

  • Here are a couple of tips to increase everyone's saliva production.

  • For starters, and this one's pretty obvious,

  • drink more water!

  • Then, start handing out as much chewing gum as you can.

  • Chewing cues the salivary glands to get to work and start producing more saliva.

  • Also, you're going to need to tell your volunteers to avoid coffee,

  • alcohol,

  • and anything to do with tobacco or vaping,

  • as they can all cause a severely dry mouth.

  • And don't worry; if that's not speeding things up enough,

  • we've still got another trick up our sleeve.

  • If you think about food, see it or smell it,

  • a reflex signal is sent to a portion of your brain called the medulla oblongata;

  • that's where your salivary centers are.

  • So, if you were to place a bunch of food that

  • looks and smells fantastic around the pool,

  • that would fire up everyone's nerve signals to get that saliva flowing!

  • Once the pool is completely full, all you'd need to do is to dive in.

  • But,

  • as you stare down at the lukewarm slime bath of DNA samples,

  • you'll start to realize that

  • you don't really know anything about the substance you're about to jump into.

  • So maybe you should get acquainted first.

  • Saliva is 98 percent water,

  • with the other two percent consisting of things like bicarbonate,

  • sodium and potassium, plus other active ingredients.

  • Saliva not only adds some lubrication to help us swallow our food,

  • it also protects our teeth and gums from stomach acids,

  • and wards off the billions of microbes that are in our mouth at any given time.

  • That's right; the human mouth is a pretty gross place.

  • It can contain up to 700 different varieties of bacteria,

  • and one of the easiest ways to transfer those bacteria to other people is through your spit.

  • And that's what makes this whole saliva pool idea pretty dangerous.

  • Some of the fun things that can be passed on through saliva include colds,

  • flu virus, herpes, hepatitis B and C, avian flu, and ebola!

  • So if you want to avoid all that,

  • you're going to want to make sure you have no

  • open cuts or wounds when you jump into the pool.

  • Oh, and definitely keep your mouth closed.

  • Even if you could confirm that every one of your spit donors

  • was clean of the conditions above,

  • you still wouldn't want to swallow mouthfuls of their saliva.

  • Right?

  • Not only would it be gross, but it would also make you dehydrated.

  • Because saliva contains high concentrations of proteins and enzymes,

  • drinking it would cause the fluids in your body to flow towards it,

  • and not toward your dehydrated cells.

  • As for the actual experience of jumping into the saliva pool,

  • it'd be just like swimming in thick, frothy water;

  • and you'd probably want to wear nose plugs.

  • Because saliva carries so much bacteria,

  • it can also have quite an unpleasant smell.

  • It's something you'd want to wash off immediately after your swim,

  • because the scent would only get worse as it dries on you.

  • But don't get us wrong,

  • when it comes to swimming in bodily fluids,

  • you could do far worse than a pool of saliva.

  • But that sounds like a story for another WHAT IF.
