My back started hurting after I got my pentablet 'cos I used it so much, I would spend practically the whole weekend sitting and drawing with it. If I didn't stretch my hand out every few hours it would cramp up really badly so I couldn't move it without it hurting.

And in art and writing I always bend right over and have my work on my lap because I don't like people looking at it, then my back and neck hurt like hell all day. I have to stop and massage myself a lot.

Thanks for making this, I'll try to do some of the preventions.
