Sims Life Span - What are you all playing with?

I don't get bored with aging off because I play with almost all the sims in my game. I'll play one household for a while, till I decide I want to do something else, and then I switch households. Before I started doing this, I was constantly starting a new game save after a few sims weeks. The game save I am currently playing now, I have been playing with for around two years now. :)
