I have extreme fear for the Grim Reaper

I think once your sim hits a certain age, you can probably turn off the aging and then they hopefully won't die. But I know how you feel. My Sim in the Sims 3 I think, accidentally died in a fire and the creepy grim reaper came. It was pretty freaky. Even the ghosts creep me out once in a while, but I haven't run into any on the new version yet. Oh and one time, I think someone died at a party I was at and he came, but then afterward, he stayed behind and chatted with people? Random and a bit creepy/odd, I think it was a glitch, but still it made me laugh a little.
