Hey, can you get sick from drinking your own piss? I believe you can
 

Astronauts board space shuttle for Florida launch

NASA plans to double the size of the space station crew from three members to six next year. The shuttle carries two new sleeping compartments and a water recycling system that will enable the crew to purify urine and other wastewater for drinking.

"We did blind taste tests of the water," said NASA's Bob Bagdigian, the system's lead engineer. "Nobody had any strong objections. Other than a faint taste of iodine, it is just as refreshing as any other kind of water."

"I've got some in my fridge," he added. "It tastes fine to me."

YUMMY. So let me get this straight. Astronauts who basically drive a space truck, blast into orbit where their job is to build a new toilet and some new bedrooms. Then when they're done they have a nice big glass of recycled pee to refresh themselves. NASA is fucked up.

Urine is sterile, so I kinda doubt it...

Give me your address and I'll mail you over a two liter.

urine is sterile unless you have an illness.

plenty of people have drank urine for various reasons (religious, survival situations).

Well now I'm starting to feel guilty. I've been wasting it all these years. Whoever wants a few two liters drop me a PM and I'll get them mailed out to you.

Yeah, uh, Patches... are you sure that this is completely necessary?

Necessary? Is it necessary for me to drink my own urine?

Probably not.

No, but I do it anyway because it's sterile and I like the taste.

Great Dodgeball reference.

I can get a little nauseous thinking about it

I'll send some. Don't mind the beer foam from last nite.

It's the only way to create a closed-loop environmental system if they are serious about getting to Mars. :shrug:
