Your position, that puberty is irrelevant, and the only thing that makes humans adults is a vague kind of "maturity" measured only by minute changes in the least-understood organ in the human body, is appallingly stupid.

I'm blocking you. Rethink your life. You don't have to be a useless blockhead troll forever.
