Chemistry

She's unforgiving and cruel.

We've all heard it a zillion times: don't pee in the pool. But why?

Urine contains uric acid, which, when in contact with chlorine, creates cyanogen chloride and trichloramine. These chemicals are bad for your lungs and can cause irritation, especially in indoor pools. So, for the greater good of us all, only pee where other living things pee (ocean: check, forest: check, etc.)!

Guess I'll just be a Liberal Studies major and resign myself to a life of couch-surfing and Top Ramen.

Suddenly chemistry makes 100 percent more sense to me.
