Do you take them? I used to but not so much anymore I find them a little too cheaty now and they make the game too easy and boring for me. Especially the ridiculous ones like 'steel bladder'
Since I don't consider making my sims lives easier "cheaty", I use a lot of them! When I am managing a family of 8-10 there's nothing boring about it and I would find them going to the bathroom or spending ridiculous amounts of time maintaining friendships boring.
