I didn't realize you were the forum Physician. I should have asked for your professional opinion before I responded to the post. Also, the US workforce is around 168 million people, I seriously doubt hundreds of millions of those people work "HARD" 12 months a year. Of those that do work "HARD", I'll bet they don't work hard when they're injured, hurt maybe, but not injured. Having said that, 95% of those "HARD" working people wouldn't last 1 quarter in the trenches of an NFL game.
PS. I'll hang around, but thanks for the recommendation to go away.
