Job is intense.  I'm actually surprised that it took until he was twelve before he broke his arm.  His ideas are not like ours.  The other day he had a friend over and they decided to make an obstacle course and attack each other with Nerf swords.  Some of the obstacles aren't exactly stable.  There is a board resting on a rope and when you step on the board it acts like a see-saw while swinging back and forth.
