I agree with that one.  Plus my body agrees with physical work more than sitting in a chair all day.  Ironic, really.  My grandfather did construction his whole life after leaving the USMC.  He always told me "get an education, get a nice easy office job so you don't wreck your body by the time you're 50 like me".  Turns out sitting in an office chair 9 hours a day destroys my neck, aggravates back problems, wears out your vision... I'm in more pain after a 45 hour office work week than I ever was doing standup physical labor for 50.
