Kennewick Man survived into his mid-40s despite pain with every breath from broken ribs and pain with every step from the hip wound. He was one tough Paleo-American. But he was not alone. That he survived serious injuries implies that others cared for him while he healed. It's not clear how he died.
Dead men do tell their tales.
To Chatters, the Central Washington University professor who fished the bones out of the Columbia at Kennewick, the skeleton is the medium on which a life was written. Kennewick Man has a full set of teeth. Cavities weren't a problem. His teeth were worn flat, evidence of eating food that had been ground or pounded on stone. Or perhaps the tooth wear is a sign of living amid constantly blowing dust.
