At least half of the people I've met that regularly do CrossFit are the kind of "anti-intellectual" cult followers who graduated from MIT & are distinguished in their fields, or have Ph.D.s in hard sciences.
Had an acquaintance with a masters in electrical engineering from a prestigious university and worked as a senior research engineer at the R&D labs of a well known cutting edge electronics firm. And I've lost count of the number of weird cults and MLM schemes he's been suckered into.
Such luddites.
