Using birthday cake for elder Sims to pass away with aging off.

I haven't had any of the accidental emotion deaths that others have had the misfortune of. The Sims that I do want to pass on are extremely hearty, if you follow me. In my case, I'm looking for something more "simple" such as the cake since I really have to try to have a Sim die from exhaustion or from emotions. I just don't have it in me because I start feeling a bit guilty when I start pushing them to that point.
