Talk to the grim reaper about grilled cheese - where do I find him?

With seasons Sims often die from cold or heat. So under or overdress them (ask to see the unsuitable outfit) and then stand around in the very cold weather or exercise in the very hot weather. Also overexercise an oldie. Sometimes if you look at list of people you know they show up as very cold, blue, and you whip over to keep them outside.
