humans are far and away superior to practically all others is long-distance running Maybe so, though his main point here is that marathon running is not healthy or in accordance with our evolution. That it takes months' or years' training to become capable of running marathons and that a runner can only undertake a marathon infrequently with lengthy recovery periods in between seems to me to support his thesis. He also makes the point that as aerobic metabolism/slow twitch movement came after anaerobic metabolism/fast twitch movement, even though we've clearly developed the capability for long-distance running, it's still less fundamental to our nature than brief, high-intensity exertion. you have to realize that evolution did not select us to reach old age, which means that it misses out on the sort of things we need to prevent aging. Actually this is the subject area in which De Vany is at his strongest. He's 70+ years old with a body and level of health & fitness enviable to most 20-30 year-olds.
