Re: What's your "day" job?
I work for a chemical company in sales. I have been drumming for 34 years (47 now) and for me it's something that should always be fun. Although I get paid when our 4 piece band does local gigs, I wouldn't ever want to do it full time because it then becomes work instead of play. I also teach a couple of kids evenings and weekends. I have tapered back on that because of the time involved; at one time I had 4 of them and it was quite a bit with everything else going on.
If it's too loud, you are not necessarily too old, you just have not been playing drums long enough.
