I'm not quite Realistic (Fictional context) because I play with aging off and if a death does happen I'm more likely than not to sidestep it by reloading a save. I'll use cheats if something totally unreasonable happens, like when the whole garden suddenly reverts to just-planted or he fishes a DJ booth out of the water that's still valued at 2000. I like there to be some sort of RL explanation to everything that happens, magic happens but my sims tend to be oblivious to it. Such as when their needs become easier to satisfy due rewards traits they tend to think they are just toughening up, when needs decay stop altogether they either think they're becoming a freak or super human depending how I perceiving their personality.
