What life span do you play?

Aging off. I wipe out everyone in all neighborhoods and settle each lot with sims with custom traits. This takes a while. Then I rotate which house I play and go to bars, clubs and parks and watch how everyone interacts with each other. It's an endless source of amusement to me. Change happens very slowly, but I do occasionally move different sims in and out, some sims have kids, and I make different lots and decorate. Sometimes I like to play with one family or sim for a long time. So I guess I'm playing with mostly immortals. Someday, and that day may never come, but someday I may watch them all on short life spans to see how long they last. But for now I like to watch them go from house to house stealing, cheating and peeing in the bush next door.
