Urban caveman movement
The urban caveman movement, a lifestyle fad from the 2010s, apparently involves:
- elements of the caveman diet
- elements of the early 1990's men's movement
- frequent fasting to mimic the long stretches paleolithic people might have gone between meals
- a lot of broscience
It is in part a bodybuilding and fitness fad. Urban cavemen go so far as to frequently donate blood (to mimic the many injuries a caveman might incur), and engage in barefoot running and "hunting and gathering" in city parks. Because most live in industrialized society, most do not seem to show any inclination to give up their cars, computers, plumbing, electricity, access to modern medicine, nor the refrigerators in which they keep their raw venison and fresh berries (which are not the supermarket variety).
Adhering to and using junk science to promote the paleo diet are also common.
"Modern primitives" form a closely-related subculture which engages in extensive, ritual body-modification (piercings, tattoos, scarification, play piercings, flesh-hook suspension, etc) combined with a desire to emulate primitive cultures in an urban setting. It is highly advised to avoid this movement if you have a low tolerance for pain. (On the other hand, one must suffer to become hip.)
