 Exactly, good advice Superdud.  I've always said excerise is bad.  when I was younger I played sports, football, baseball, softball, basketball, I even ran.   I suffered from several injuries, torn ligaments, sprains, and cuts, gashes and stitches.  Now that I'm older I avoid excerise when ever possible and suprisingly I've had no injuries.
