Not talking about the Jeremy Robert Johnson story, although it’s one of my favorites of his, but the kind of endurance running we hominids used to use (used to use more) to run down prey. I mean, of course we did that—it’s what my “Chapter Six” story argues. Also, I’ve read accounts that, in the Great Plains, long before Kevin Costner got there, it was kind of a Sunday sport for white guys (I specify because in the accounts I know, it’s only ever white guys doing this) to find a wolf, put on some old-timey running shoes, and take off after that wolf. Trick is, that wolf’ll always stay just ahead of the runner, and after a while it just dies. This always struck me as half made-up, since we all see the helicopter footage of wolves bounding through snow for half a day after an eventually foundering elk. And they’re not dying then, are they?
