I recently came across what could be a a bit of a problem. My founders spouse, about 5/6 of adult life, was busy trying out handiness and fixing a TV when she got shocked an instantly
died. I nearly had heart failure I was so upset as I'd just spent ages leveling up her fishing and gardening for ingredients to give my founder to cook with. Anyway, she was then visited by Grim and he laughed or something and said he felt too sorry for her with her luck to take here away, and so she survived. I later realized that it was because of her Unlucky trait and felt ecstatic because she now had a full adult life ahead of her yet again!
My question is, won't people abuse this feature to keep founders and heirs/spouses alive fr longer? There aren't any restrictions on traits and it isn't too difficult to get a Sim to die in this way with the technophobe trait (to break stuff) and then fixing or even inventing.
