You can explain this without putting down men and their hobby in the process. I don't think it makes women smarter, more sane, or conversely make men idiots, or show offs or any of the other ridiculous explanations I've read. I think as maguiar102 says, men are more compulsive about certain things, especially electronics, or cars. But believe me, of you have ever seen some of the women I know talk about the things they're interested in-decorating, their personal appearance, fashion, you would think the same thing.
It's just what we were socialized or wired to do.
