My oldest living sim (in terms of past life expectancy) was an elder I created name Ingrid. I had their lifespan set to 126 days (I believe) and she lasted to day 198 and then her dog begged for her life and brought her back. On day 201 I used the age on instant on her cause I figured it had already been her time to go and no telling how long it would take to come back around and if that dog would beg for her life again.
I did feel guilty for using the age of instant on her. I've often wondered how long she could have lasted, but I seriously was ready to move on with her granddaughter and great-granddaughter.
