The 'Tarahumara' use their legs 'as designed.' By running at a young age with minimal footwear, they naturally develop the best biomechanical use of their legs. Cushioned shoes restrict foot movements and allow for over-striding. Short strides are natural.

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.

As I have discovered by examining my past, I started out as a child. Coincidentally, so did my brother. My mother did not put all her eggs in one basket, so to speak: she gave me a younger brother named Russell, who taught me what was meant by 'survival of the fittest.'

From a good lie in the middle of a fairway bunker, I'll make the same swing as I do from an average fairway lie. I'll dig my feet in slightly and keep my lower body stable so I won't slip, but I don't change my club selection or setup. It's only when the ball is sitting down in the sand that I'll make some modifications.
