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 designed for persistence hunting, which is a mix of running and walking. What's built into that kind of running is a sense of pleasure. You are designed and built and perfect for this activity, and it should be enjoyable and fun.

If ergonomists have their way, future products won't be built for some hypothetical average person but will conform to the biomechanical needs of whatever particular human body happens to come into contact with them.
