Hello. I am 26 (going 27 in February). I considered myself rather late in comics, seeing that I only really got into comics on my last year of high school. I may be one of those odd ones who started by drawing instead of seriously reading. Hahaha!
I continued until first to second year of college, then everything just got busy.
I got back into it again around 2012, I think, but never really did a lot. I was on and off.
So yeah, I can say I've been into it at least 2 years...
Also, I am actually happy that there are a number of middle-aged people here. For me, being that old and being in comics is a cool thing. It gives you a point of view that younger people won't really know about until they get there.
