Do the offer a course in bullet proof skin, x-ray vision, and the ability to breathe underwater?
I once stayed underwater too long and hallucinated that I could breathe it. Lack of oxygen to the brain does weird things. But I wasn't crazy enough to actually jump back in the water and actually suck in water hoping to breathe like a fish.
But now that I'm old enough to recognize what the euphoric hallucination meant, I'm glad I wasn't a crazy kid prone to believing everything my brain tells me. Brains can be fooled. Not everything perceived is real and not everything real can be perceived.
Oh, and word of warning to parents with young kids... Keep a close eye on them when they're in the pool. I'm one of the lucky ones.

This explains many things. :-)
