Not sure if this really counts, but my sims' life span is 242 sim days. Since I play rotationally within each (Traveler mod) connected world though and these sims do not age and progress meaningfully unless it is "their turn" and I am playing them actively myself under sort of a modified version of TS2 style aging by way of NRaas SP, they do get to experience well over 1,000 sim days each in total depending upon how many households I have to rotate through in that world. Some would be more like 2,000. That's kind of like epic, maybe?
As for how slowly I play, sheesh. I remember announcing the birth of my first triplets to some other players and non-simmers who I am sure were only pretending to be interested over four realtime years ago. These triplets are still less than halfway through their teen stage now. :)
Technically my founding sim and his partner are still alive, although they really shouldn't be. I parked them in Starlight Shores in permanent retirement ages ago, but to this day I can't seem to bring myself to make that world active by traveling there and having them pass away from old age so I can bring their remains back home even though I know it would be kind of fun to have them around again as ghosts. :'(
