Nope. Real adulthood starts around 35 though. Possibly a year or two earlier. I've always thought the worst think about human lifespan is that, in modern times by the time you get educated and mentally/emotionally adjusted and enough time to really get proficient at a craft you only have like a decade or less before slowdown starts. Then you have the other half of your life being "old". In more primitive times (most of the history of the species) I believe a person was basically a small adult at puberty. There wasn't much more to learn, there wasn't a great deal to "experiment" with, crafts and trades were simple enough to be picked up in a few years. You had kids early and generally died at not much more than 40 and that was that. Although I'm opposed to immortality (until we get some other things worked out) it would be cool if we could stay in physical/mental prime for the same proportion of lifespan as we did in earlier days. Because adulthood begins so much later.
