I kinda' got in the habit of taking short breaks many years ago when I was a kid playing lead guitar with a bunch of guys I was in the navy with. I think the longest break I've ever taken was maybe 15 minutes, and I think that was only once when one of the keyboard's crapped out. When I was 50, there were lots of body parts that were still functional--now some of those parts are missing. Gettin' old ain't fer whimps and sissies!
