I think it depends on whether, when you go clubbing, you just:
A - Have a drink and dance your socks off with your friends
B - Have many, many drinks, lurch around the club unsteadily, shake your booty invitingly at any member of your preferred sex, and then proceed to get off with them on the dancefloor and then shag them in the toilets.
If you're in the A category and getting on a bit age-wise, I suppose it is far more understandable to want to continue clubbing.
