This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Why
Because you can have a little salt, as a treat.
You certainly won’t regret drinking a half gallon of salt water
Because your kidneys can filter out a certain percentage of salt, and that's based on the blood concentration
But if your blood goes above the level where the water is being drawn out of your cells and drying them out, you'll be dehydrated from the inside out
Why
Salt is hydrophile, which means it attracts water.
Real worried we're going to enter a Richard Feynman level why spiral
I felt bad for the interviewer at first, until the guy really got into his explanation. He wasn't being a dick, he was just saying "why" is a really deep question.
Yeah he does start out a bit blunt thankfully it had a point.
Why?
because salt and water happen to be composed in such a way that they fit together nicely, and salt attracts the water in a similar way to a magnet. The positive and negative charges of the salt ions (Sodium+, Chloride–) fit into and attract the opposite charges of the water ions (Hydrogen–, Oxygen+).
It's simple homeostasis, homeslice!

Evolution and shit
It's from homeostasis, homefry!
That is a good question for a nephrologist.
It's your body doin homeostasis, hombre!
Your body needs some salt, and it sweats out salt. So it needs to be replaced.
