I wish more people were like you or I. I'm 41 and love being this age and its not due to anything physical. I love it that I'm ok w/me and that feeling came at 35. Its funny @ work I work with lots of 20 somethings and they think they know everything about life and make major crises over stupid events in life that I would now blow off. I would never go back to that age its too good now!
