Hm I don't know much about the male pregnancy thing, David never said anything about that and I never saw anything about it. I looked around a bit on the net and saw some rumors before release about alien abduction but haven't seen anything about it while watching hubby play.

I did see someone who posted on a sims message board that their sim kids got abducted by aliens in Sims 1 after they kept looking through the telescope all the time.

Maybe it's just an optional thing for those who want a silly factor or maybe even for people who believe the possibility of it, who knows .

I did read that the new sims can die of old age though.
