Are you suffering from kidney stones? Just book a trip to Galaxyland!
David Wartinger, a urological surgeon, had heard stories from patients who went to Disney World and returned with fewer kidney stones. But he didn’t think the two were really correlated until one man recounted his experience with the Magic Kingdom’s Thunder Mountain.
The man rode the ride, and passed a small stone. Then he rode it again. And passed another stone. A third go around — a third stone!
Dr. Watinger conducted a study using a fake kidney made from a 3D printer, and headed to Disney World to test the theory. After 200 roller-coaster rides, they found that — due to the centripetal force of the ride — the small stones passed through the fake kidney 63.89% of the time when sitting in the back of the coaster, but only 16.67% of the time when sitting in the front.
Passing a stone by enjoying a day at the theme park sounds a lot better than the traditional method!
