I have a running joke with my wife about the fact that I can't float on my back in the pool. Well, she thinks I'm joking when in fact I'm completely serious. She doesn't believe that a person is incapable of floating in water, even though I've repeatedly assured her that I sink like a stone. I've even demonstrated the phenomenon for her, but she told me that I was doing it wrong. I didn't realize there was a right and wrong way to sink to the bottom of the pool, but I guess I've mastered it.
Well today, I was watching The Big Bang Theory, and lo and behold, Sheldon admitted to have the exact same problem! He said the issue was that he had a higher than normal body density, which sounds completely reasonable and plausible. So now, I finally have a reason for my inability to float in the pool that my wife can't refute. It must be true, because not only did I see it on TV, but Dr. Sheldon Cooper is generally accepted as a genius, so he must know more than us.
