I questioned this myself when I started taking my first drumlessons at age 19. I was interested in this instrument at a young age, around 7 or 8. One of my nephews played drums and I got my first pair of (broken) drumsticks from him. Played on any thinkable surface with thise sticks. My parents found it more important that I played soccer or any other sport. They couldn't afford music lessons.

My parents got divorced and my mother found a new partner. He played drums from young age (technically not that well, but he has fun in playing and can bring his enthusiasm over to other players

). At age 17 I was confronted again with this highly contagious virus called drums. Started playing along (terrible) with dire straits records, Stevie Ray Vaughn records for some years. When I was 19 my mother's partner convinced me to take drumlessons. After my first lesson drumming became a part of me. Practiced any free hour.
Now going on 35, reading this threat, not being a pro but just an enthusiastic hobbyist, still love to practise and play, seeing my almost three year old like banging on my drums and cymbals, made me come to the conclusion that starting playing drums at an "older" age was one of my better choices.

. So IMO, Your never too old!!

buying 15 K Dark, 17'' Avedis brilliant, 13 A custom hi hat, 20 Paste Dry Signature ride, 11 en 14 '' UFIP Class splashes,
14 * 5 Worldmax black beauty snare (yes the imitation, only the third of a Ludwig and sounds just as great (referring to the Steve GAdd snare threat)
