clubbing past 30 all depends.
For some (like me) it got old if you hit them really HARD and OFTEN. I ran the process into the ground when I was young, single, monday - sunday, VIP everywhere, everybody knew me. After all the females, night life, clothing, paging(no texting), quarters for the pay phone,late night hook ups..etc for years and years it all got old fast. I enjoyed the moment.
Most to all of the crew I ran with back then running the streets are the same way as me. We killed it and moved on.
All the people I know past 30 still clubbing now outside of that bunch just haven't had enough experience to get the club scene is all the same all over.
