I think this is a really interesting and relevant thread, which concerns us all, but seriously can you see everyone doing warm-up and cool down exercises, at the end of the day, the human body is like anything else, wear and tear in a physical job will get to everyone, but then on the other hand, the exercise also does you good, i know what i prefer, and its not sat in a office with risk assesments for my chair and desk, like at my mrs work!
