Friday WTF. What's next, blood-letting?
Another pseudo-scientific fad, or a revolutionary old-new re-discovered invention?
The bodies of a number of Rio Olympic athletes have been covered with red circles from cupping.
Presumably it helps increase blood flow and heal sore muscles. Remember those stripes of tape that athletes used to put on their muscles a few years ago? Seemed like another fad, which has come and gone. Anyone have some more insight into this new devilry here?
