as a 51yr old father of 11yr old twins (one boy, one girl), and reflecting on how I have myself matured (lack of!) I can honestly offer an opinion that humans may be physically capable of sexual reproduction early mid/teens, but that doesn't make them adults. Likewise 20s and even early 30s. I was a selfish prat right up to having kids. Having kids completely changes your priorities and outlook, including CONFIRMING that kids are, literally, the future. So you're right about preserving the future for younger generations. BUT if adults don't become adults (really!) until they have kids, and human kids can't look after themselves, and anyway don't mature mentally til they have kids, we come full circle, that is why you need 2 generations minimum at the same time. HTH!
