I haven't ever worked in a 20-something only culture. I was the young guy when I joined my company, most of the team was in their 30s, some in their 40s. Over time it helped me grow as an individual, and it also helped me to grow professionally. Anyone who's had a few more years of experience probably has something wise to share with you, whether they know it or not. Hell even those with less experience often have a different perspective that is worth listening to. I guess what I'm trying to say is none of us should live in an echo chamber and we should all try to be open-minded (but maybe that's a little heavy-handed).
