whoooaaaa....!!what about this aging thing??population decrease?

[Truswagga]

so i read that the neighbors age as we do. You know i was definetly thinking about that and i am glad a little but a liyyle worried. im not worried about my other sims dying, im worried about the fact that townies never willingly woohoo.Well atleast i never seen one willingly woohoo because they were attracted to someone. to be honest i never even seen one flirt wih another townie. Will the population decrease? Will townies atually start woohooing and starting a family of their own?Or will a townie generator start creating sims as others die off? will sims decide to have their first woohoo? Whats the deal with that? GIVE ME ANSWERS PLEASE. ??? WHAT IS YOUR THEORY ???
