A colleague dropped off a list of male mental and behavioral characteristics. Since he is a psychologist, I imagine that there must be some empirical research to support these claims. Perhaps you can help me by providing references to relevant studies. Here are two from his list: (1) Why does it take 200,000,000 sperm to fertilize one egg? Because they don't stop to ask for directions. (2) How many men does it take to put a toilet seat down? Nobody knows: it has never happened. Thanks in advance for any help you can give.
