We don't woo our wives with clubs. We don't leave old folks on ice floes. And maybe the time has come to quit diving into rip tides to save people we don't know. We've outgrown a lot of survival-of-the-fittest strategies, and risking our lives for strangers might be one of them.

Endurance, after all, is the only reason we even exist. We think of ourselves as nature's deadliest animals, but the truth is, a naked human is the biggest wimp in the wild. We have no fangs, no claws, no strength, and no speed.

We're constantly told that running will ruin our knees and outrage our hearts, but for nearly all of human existence, it was associated with freedom, vitality, and eternal youth.
