When it comes to the top 10 health risks facing American men, the Tarahumara are practically immortal: Their incidence rate is at or near zero in just about every category, including diabetes, vascular disease, and colorectal cancer. Age seems to have no effect on them, either: The Tarahumara runner who won the 1993 Leadville ultramarathon was 55 years old. Plus, their supernatural invulnerability isn’t just limited to their bodies; the Tarahumara have mastered the secret of happiness as well, living as benignly as bodhisattvas in a world free of theft, murder, suicide, and cruelty.
