There's a young man skateboarding through a two lane empty road that has trees on both sides.  He goes steadily through the long and winding road without stopping.  He passes through curves and turns around to adjust his speed.  Then as he approaches a steep curve, he tries to turn but ends up falling down and bruising himself.  He gets up immediately and shows his friends his scraped and injured elbow.  Another friend of his also shows his injuries that he's had from skateboarding.
