A lot of human survival is based on heuristics, if you can tell there's a corpse in something, you probably shouldn't drink or eat it... As a general rule of thumb

For large body of water since you're unaware of the corpse two kilometers away on the bottom, it's probably not an issue for you.

However, primal human heuristics are not calibrated correctly from modern media. There was the reservoir where somebody was caught on camera peeing into it, hundreds of millions of liters of water, and they decided to drain the entire thing to prevent the public concern. That's just a heuristic run amok

And this is why it's dangerous to drink ocean-water.

Also why you should drink lots of that delicious peepee pool-water

ETA: If you're having dinner with someone who dies in the middle of eating their food, you can safely finish their food, drink, and poisoned soup as long as they didn't die face-down in it.

my body is a machine that turns piss into piss

[–] [email protected] 18 points 4 months ago

That's what's literally happening in your kidneys. Your primary urine is low concentrated, and gets converted into high concentrated secondary urine through several fun biophysicochemical reactions. Boring piss gets to be exciting piss. Wohoo?

The salt an ocean water will make you sick long before you get sick from decay-based pathogens. Takes about 100 g of salt to kill somebody...

And the chlorine and pool water will probably make you feel poorly as well.

You sound like my doctor. Quit ruining my food and gimme my blood-pressure medication!

And this is why it’s dangerous to drink ocean-water.

i thought this was because it was salt water?

You need sugar-water to counter it.

how much sugar salt water is needed before my kidney explodes?

[–] [email protected] 2 points 4 months ago (1 children)

You need to aim at hyperglycemia and diabetic shock so you don't need to worry about your kidneys alone.

[–] [email protected] 2 points 4 months ago

oh, yeah true i could do that also. Or i could just bomb my kidneys.

Also what is the intermixing of water two kilometers away, especially affected by currents (which I presume, without checking ofc bc this is the internet 😁, are more horizontal than vertical - thus would intermixing occur more readily on the horizontal but the fact that it's vertical distance mean... what really)? So yeah, it makes sense then that due to the unknown factors, the default would take over.

[–] [email protected] 6 points 4 months ago

Sometimes the water sits stable with next to no vertical intermixing and sometimes it intermixes to homogenity. Depends on the external conditions
