What is the perfect age if you could stay there? I think it depends on who you ask and what age they would enjoy being for however long they wanted to. For some people I suspect they would like to be age 12 forever. Having a golden childhood might enhance their selection. I had a decent childhood but I would never want to be eternally set at age 12. Can't drive or go anywhere you want, when you want. I feel the perfect age is 36. You are not too immature to know the finer things in life and still young enough to participate in rigorous endeavors. Young enough to play a few pranks on friends yet old enough to take on adult responsibilities. At age 56 I think was not the perfect age for me. For many it is a time of a higher living standard and a better position [hopefully] in one's career, but who wants to live with the aches and pains, the root canals, the pharmacy visits and screaming grandkids forever. I guess on the plus side your own children are grown and have their own jobs and the grandchildren are not over every day. So I can see some trade-offs, and blurring of the decades along the edges.
