We have been playing for the same amount of time. I am glad us old timers keep up, or at least try. I do not have any physical issues with playing yet, save for a few times when arthritis in my thumbs give me a bit of trouble, but I play through the pain. I refuse to give up the love of drums.
Hi, I am 62 years old and have been playing since I was 10. I play drums primarily, bass guitar and keyboards and have mastered the djembe, which is like playing a set of tom toms on one drum. Not much for jazz, but as to straight up rock or metal, I have no trouble keeping up at all.
