I don't get it either. You'd think being on your feet all day and having to lift patients would be enough of a work-out. When I gave birth to my son, there was one in the nursery who was at least 400 to 450 pounds. Maybe even over 500. It was gigantic. It was the kind of deathfat that you stare at and try to figure out how it's still mobile. It had picked up my son to administer treatment, and honest to God, my first thought was, "it's gonna eat him. That thing is going to eat my son." I may or may not have still been a little loopy from the painkillers.
