Vito, once again you're right. I am jealous because I can't chase after a 4 year old when I'm 75, like a man can! Whew! Caught me again!

Edit: Regarding your point about men having children when they're older, it's a personal preference. I would want to be young enough to enjoy my children. As I get older, I find my physical limitations growing with each year. How long can someone expect to live? What are the chances that if you have a child at 70, you're going to be around to see them mature? I know that there are no guarantees in life, but I feel that you owe it to your children to at least be a statistical probability in their lives.
