It’s the quantity. And also, by the time you’ve filled a cup of spit, it has cooled and dried a bit, maybe even breaking itself down, resulting in an increased viscousity, giving it a very unpleasant mouthfeel.
I get that the OP asked a question, but did you have to answer it with this level of detail?
I can’t help it. When someone asks a question, I spit up an answer
Do you expect us to consume that?
You’re going to turn down a perfectly good cup of spit in this economy?
Same reason you wear your socks the whole day but once you remove them they become eww. Human brain is weird in that regard. Probably has evolutionary reasons but from an entirely rational POV it’s weird.
I had some oral mucositis that caused some excessive saliva production. There was one time I accidentally swallowed a mouthful of it, it immediately caused me to vomit.
spit up
I’ve swallowed a mouthful of spit a couple times. Rather unpleasant experience.
Thanks…now I’m acutely aware of the spit in my mouth and when I swallow it.
Fluids that exit the body is like this. Only exception is blood from your own kin and tears. Anything else gets very dirty once out of body. Sweat, urine, vomit etc
Spit in a cup and drink it and watch how your peers react.
Are you drinking your kin’s blood and tears?
No - but wiping it off is no issue. If you drool on yourself I’m not gonna touch it
You are swallowing that saliva during the day. Usually we make 0.5 and 1.5 liters daily (for us measurements 2 to 4.2 cups). And that needs to go somewhere. And it is very important part of our oral hygiene too.
So in metric the range is 3x and in imperial is 2.1x?
Freshness?
