werebear, in your first post you mentioned your back problems. The only thing that has ever helped my back
is careful, measured exercise. You might even see a professional (M.D. or chiropractor) to get exercises that
won't hurt you. Abdominal muscles hold the vertebrae in position, so exercising the core helps the back, but
you have to do it carefully. You'll get plenty of exercise at work, so you will mostly only need some limbering
and stretching work, but I think this could ease up any pain, and worsening of back problems. Again, congratulations
and stay well.
