It is especially in the first generations but their are many schools of thought on increasing longevity. feed the the fruits and vitamins from the store, buy only organic groceries,get the pool and treadmill and encourage exercise.... for the most part I have found in the early generations I can get to 65 easily just by purchasing the fruits and vitamins in the store whenever they show up and giving them to the parents. also I don't discourage exercise but don't praise for it until they have mastered their career.
