I like the young people's groups too, though I never figured out if they are for people who are young, or people who got sober young. I just assume the latter. A group that was based on just being young by its nature would exclude all the wisdom that only age can bring.
It is a mistake to dismiss the old folks. For one thing we don't feel old. I liked the old timers and when I knew what to listen for, they were a huge help and inspiration to me. But we had our rebellious young folks too. They seemed to think they had a different disease for which the oldies had nothing to offer. Most of them are not around today. The strange thing was while they didn't relate to the oldies, I didn't relate to them. That worried me a little at the time as I thought I am maybe not a proper young person. However sticking with the winners, regardless of age, proved to be a wise course of action.
