I let unplayed Sims age up but there are some Sims i don't want to age up at all. You can use MCC to flag Sims one by one but i wanted to be able to add/remove a No Aging Trait easier. So i added a Pie Menu to Computer/Tablets where the No Aging Trait can be added/removed to Sims (mind. Age Toddler)
Sims with the Green Thumb trait excel at gardening both at home and as a career. They not only learn gardening quickly, but they have lots of fun doing it and even have extra bursts of energy just so they can get in some extra gardening before the day is over. They also excel at other botany related skills such as flower arranging and herbalism. It’s not all sunshine and roses for a Green Thumb but if you want to work with plants in any significant way, then this is the trait for you!
