A Bolivian man who officials claim is 123 years old — which would make him the oldest person ever recorded — credits lots of walking and a diet that includes barley but not noodles or rice for his longevity. Also, "like most Bolivian highlands peasants," Carmelo Flores Laura has been chewing coca leaves his entire life and still does today. The coca leaf is a "mild stimulant" and the source of cocaine, but it is not cocaine. We just put that in the headline to pique your interest. Don't do cocaine.
