re: re: Yes
There's certainly such a reason.
It's just that it's so difficult to find a girl or a woman who's interested in that too (I know only a few examples).
I read the other day of a guy who's got to give 10 cents to his wife every time he opens his mouth with a space-related topic.
I do talk a lot and especially about space (just can't avoid it) but I'm no too sure to be so successful in catching the women's attention.
