WITHIN OUR OWN FAMILIES, WE HAVE TEENAGERS WHO WILL PUMP IRON FOR HOURS PER WEEK, DO INSANE PHYSICAL FEATS, REPEATEDLY, FOR TIK TOK, BUT WILL NOT DO ANY OF THESE SIMPLE PHYSICAL ACTS FOR AN HOUR OR TWO A WEEK: PICK UP THEIR ROOM, PUSH A LAWN MOWER, RAKE LEAVES, DO THE DISHES, TAKE OUT THE TRASH (without having to be asked, or having a knock down, dragged out fight).
