I suffered and still suffer a lot of ageism for looking young. Even now, I have people lecturing me about "wait till you get older..." and it turns out they are ten years younger. For that reason, I don't enjoy communities that are age restricted. Both old and young age limits cut groups off from experiencing the world. With permaculture as with any hand craft, communication between generations is the fastest way to progress.
So, what's the Permaculture approach here?
I think it's interesting how most people feel most comfortable communicating with their own age group. I can't help but worry we miss opertunities staying in the comfort zone.
I also wonder about the advantages of helping established generations learn to speak with up and coming ones? To open that dialogue. Expand the comfort zone. We have a common topic of conversation, permaculture, to fall back on. Instead of seeking age specific methods of communication, we seek comfort in a shared topic?
A thread I really enjoyed along these lines is this one.

Perhaps starting a new one for your age group woul help open the conversation.
