I'm disturbingly close to my 40s myself and I'm a bit worried by your comment. I'd imagine that any novelty that the young'uns would have to you or me wandering into a yoga class/room full of programmers would wear off quickly when we just do our thing like everyone else and fail to fall on our faces or do anything else to draw negative attention to ourselves. I'm far from a social butterfly, but I've yet to feel any particular awkwardness (more than normal, anyway) due to my age when joining social or work events which I have been invited to. I'm sorry if this comes off as a bit brusque, but maybe this is a self-confidence thing on your part.
