My work was always in the lab, which has it's own set of issues for backs and not to mention pipetting RSI, but now that I'm trying to write up my theseis I'm always in front of the computer. Then I play online at home too. So yeah, same with me.

I'll read a bit more and put down the exercises that look the most useful. The guy says you can do them while waiting for the kettle to boil or brushing your teeth. He also says walking is one of the best things you can do for your back.
