I haven't played guitar in many days. It has something to do with time, but a whole lot to do with pain.
As my job requires me to spend all day on the computer, and a lot of my leisure time is spent here also, I use my hands for keying and "mousing" a lot. And, of course, my posture and typing/mousing habits suck. I have, over time, developed tendonitis in my wrist. Which, because I ignored it long enough, has caused me to put pressure on different areas of my arm and I developed pain in my elbow and lately I have begun to feel some pain in my shoulder.
So, not only does is hurt to stay on the computer for too long, but it also hurts to play guitar and that really sucks.
Guess I should start wearing that damn wrist brace.
