I guess I have the opposite issue. I mostly play in settings where the majority of the players are half my age. I like what they do much better than the kind of thing most of my contemporaries do, and I have a great deal more respect for their technique, knowledge, communication skills and imagination than I do for people my age who are just freewheeling downhill to the point where their guitar is decorating the wall in their eventide home.

Whatever age you are, you can tell when people are putting in a serious effort, if that matters to you. And I guess people who don't want to try hang together too - that's what a lot of events labelled as folk or trad are for.

Be inspiring and you won't see a problem.
