I don't know. Coming from an age bracket that would be called young on this board, I do have to say that it does depend on the individual. I do have acquaintances that are around my age that act as though they were still in high school, but on the other hand I have friends who act their age, or are even more "mature" than they should be. Mature is a very subjective word. When your 10, mature is knowing that you shouldn't pick your nose, but you do it anyways. When your 20, mature is when you are going to school, have a vehicle, and are making a living on your own. 30, 40, 50, does it stop? Every age has its own characteristics that make it interesting. I would imagine that a 20 year old has more energy than someone who is 55-60, but on the other hand, someone who is 55-60 probably knows "what a women wants" better than the 20 year old.
