Revisiting the One, or setting the Wayback Machine to your first Sim

My first sims created since the beginning were my simself and sim husband. They are still alive but elder. I was just thinking yesterday when will I let them pass on....? Maybe when a great great grand child becomes a child. That way I can hold on to them a bit longer. So far they have a toddler great grandson. Yea...that's what I'll do.
