Here's another good reason to floss - it could save your life. A couple weeks ago a 62 year old was ice skating on the Mississippi River when he fell in. He spent about an hour in the water before some local help, including his own son, were able to retrieve him - but it wasn't easy. The man disappeared under water so the son dove in and kept him afloat while the rescue team worked the rope towards him. The problem was that after an hour in the icy water, his hands no longer functioned, so his son suggested he bite on the rope while they tow him to safety. It worked, the man survived, and today he has his healthy dentition (as well as his son and the local law enforcement) to thank for it.
