To answer your question directly, I think the only way you can "age out" is if you make that determination for yourself. We've heard about how some stage doors can get more chaotic/crowded especially for certain actors and even amongst my own friend group of people mostly in their late 20s I have friends who just can't be bothered to deal with that anymore even when they're a big fan of the actor or show. So they would joke about "aging out" of doing stage door just because it isn't worth the experience for them, but I think that's something for each person to decide on their own. I've certainly never thought of it as solely a young person's activity."
This is my experience. Around 25, I thought “I’m too old for this” even though I’d had so many great experiences. Rushing out after (or something, admittedly, during) curtain call, stressing out about getting a spot, dealing with rude or pushy people, worrying if the person I wanted to meet would come out, sign, be nice, etc. I wouldn’t make that determination for other people but it was my personal decision.
