Can Roller Coasters Help You Pass Kidney Stones?

The video discusses a study suggesting that riding a moderately intense roller coaster, like Big Thunder Mountain Railroad at Walt Disney World, may help pass small kidney stones. Researchers created a model kidney to test this theory, finding that stones passed more frequently when sitting at the back of the ride. The video also covers a study on Earth's temperature changes over the past two million years, indicating a warming trend linked to CO2 levels.
