What Water Are You Not Supposed to Drink
Seawater is 3.5% salt. Your body needs 0.9% salt. Drinking seawater makes you more thirsty. It triggers diarrhea.
You die of dehydration while surrounded by water. That's the cruelest joke the planet plays. Stick to the freshwater, friend.
What about "raw water"?
This is a trend. People buy unfiltered, untreated water. They think it's natural. They forget that "natural" includes fecal matter and cholera.
It's the same as drinking from a puddle. But with a fancy price tag. Your ancestors didn't drink raw water. They died young. Learn from history.
