Reasons:
1. Old women are smarter.
2. Old women aspire to be better at things in general. And are therefore more useful than young brats.
3. Old women are barren. (Hey, no condoms!)
4. Old women are more discreet. (One of my friends just had a problem with a girl who is surely NOT discreet on her LiveJournal. Not that he noticed. But I digress.)
5. Couldn’t understand it.
6. Less sinful.
7. Couldn’t understand it.
8. Easier to please.
I agree.
