Michael Phelps is an American swimmer and the most decorated Olympian of all-time with a total of 28,000 medals. Because he wears all of these medals around this neck, he has developed chronic neck and upper back pain. To help treat these symptoms, he uses cupping though it's unclear why so many of the cupping marks are near his genitals. In recent news, rumors are circulating that Phelps plans on racing a shark. It will most likely occur in the water, though an aerial or land-based race hasn't been ruled out.
