Well, maybe not a miracle, but bizarrely interesting. (See https://www.theatlantic.com/health/archive/2016/09/for-kidney-health-roller-coaster-therapy/501278/)
But one particular gentleman really inspired Wartinger. The man rode Big Thunder Mountain Railroad at Disney’s Magic Kingdom, and then passed a small stone. Then he did it again and passed another. And then another. “That was just too powerful to ignore,” Wartinger said. “I’d been hearing these anecdotal stories for a couple years, and then I thought, okay, there’s really something here.”
If you plan to do this, Dr. Wartinger found that you get the best results from riding in the last car.
Although only a preliminary study, Wartinger suggests this method might save big bucks.
I wonder what a screen of rodeo bronc and bull riders would find.
