New word for you: Telegony
It's just scary that people fall for such bull, especially in 2007. If I was stuck in a telegony-believing society I'd tackle the first guy that looked like he could get me thrown out.
FYI: There's a certain female in my house :shrug: that has tested the telegony theory maximally, and has produced 3 kids (marked with their daddy's dimpled chin) as evidence that telegony is pure bunk. There's our household's contribution to science. You're welcome.
