Your back or your knees

Miniature painting requires intense concentration and many hours in a stooped position, either sitting hunched over a desk or with the painting propped up on your knees. So you have a choice - one day, either your back goes or your knees go. Which will you sacrifice?

For me it's likely my knees (they are ugly anyway). My back is important. Well, my whole body is actually important, but if I had to choose...

I wish I didn't have to choose. Someone should start a miniature painting yoga class to correct our posture.
