You can even make your Sim a bedwetter if you really want to be cruel. Of course, the younger the Sim is, the more prone he or she will be to having an accident, just like in real life. This mod comes from sachamagne over on Mod The Sims, and it allows Sims of all ages to wet the bed. That being said, I'm not exactly sure why you would want to give your Sims more opportunities to have an accident, but in case you do, there's a mod out there to satisfy that desire. Just like human beings, if you don't get your Sims to the toilet in time, they wet themselves. This reminds me a lot of that movie-turned-TV show Limitless, so you can use this mod to live out your Bradley Cooper fantasies.
The Awakened Mind Trait mod created by alan650 on Mod The Sims gives your Sim an 'advanced' brain that makes it so they rarely need sleep, advance their mental skills quickly and never experience discomfort, which is about as far from being human as you can get. If you want your Sim to act like the Energizer Bunny, there's a mod for that.
