Still playing competitive sport 40+?

I've just finished my 28th season playing basketball this week. It's a very low local-level league but still an organized sport, sometimes against significantly younger players.

From my age social group, many still exercise, gym, run, etc., but not many still play "competitive sports" in properly organised matches and leagues.

Who is out there still playing "competitively" at 40+ in team sports?

Do you play vets, or are you still teaching 18-year-olds what's what?!
