Our modern culture makes it hard to get physical activity unless you just  
want to.  But if you want to, there are plenty of opportunities for  
physical activity, even without "exercise".  Walk the last couple of miles  
to work.  Take the stairs instead of the elevator.  Don't use power  
tools.  Find something to do besides watch TV (preferably outdoors).   
Play.  (That last one is an easy, fun, and cheap way to get some good  
physical activity, but so few adults do it.)
