So I've technically let a girl bleed all over my chest? Ew!!

*tract (unless you swallowed a bunch of Mario Kart toys)

i once had a VERY spicy meal. and i'm quite used to spicynes

that meal caused me to feel it the next morning when i peed. which also means that my blood was spicy at some point

Guess where almost all your fatass has to go in order to lose it? Your lungs. You have to breathe out more than goes into your face hole. That's a lot of breathing.

That, and then you realize that you primarily lose weight through your breathing.

Listen, urine comes from your no-no spot and I want to drink it straight from the tap because I am an alchemist and know urine's true potential. Please, everyone, pee on me to make me more powerful, and I will defeat Donald Trump in this next election...

I think that makes sense, water is absorbed into the bloodstream, right? And then the kidneys filter the blood and the bad bits + excess water is peed out. Which is why your pee looks saturated yellow if you are dehydrated and almost clear (but don't drink it!) when you have drank a lot of water.

Any remaining water in your digestive tract that isn't absorbed would be in your poos! If you have diarrhoea and your poos are all liquidy, that means water is not being absorbed properly (bad!)

I didn't do Biology, I'm a Physics+Chem student, so this could be completely wrong!

Digestive tract

Don't like this new knowledge. Not a fan

And when you lose weight, you breathe it out.

Fun fact: what ever you eat is wrapped around by your body, but it's not in the body.

Humans are topologically a seven? hole donut.

If you don't take in any liquids for long enough you won't have any urine. It's carried by your blood from source to destination. Your sweat similarly is from liquid transported by your blood

Wait until you find out where milk comes from.

I mean... It's not like there is a tube from your digestive tract to your kidneys... How else would it get there?

Btw, I'm really smart and humble if you didn't notice

Instead of 'You are what you eat.' it is "You are what you don't shit."

W T F ?!?

It all comes from your digestive tract. Unless you're getting iv, subq or even more interesting io fluids. Though if you're getting io fluids your kidneys are likely getting fucked up enough to not produce urine for awhile and if you're getting subcutaneous fluids you're likely a cat or a dog or something.

Me just now

peeing blood is a thing. liquid can come out of your intestines if you get norovirus.
