Hands do the Work

RSI has been for many years a problem, along bad posture and back complaints. Many computers users become so engrossed in their work or computer-based activities that they forget to get up and stretch their limps, which leads to progressively worst problems

An aid to combating RSI or related conditions is Workrave which can be downloaded from here

It is open source and works across a number of platforms.

I confess I use an old egg timer instead but give Workrave a try.
