It's ice-cream-eating season and the "Flavor Guru" at Ben & Jerry's has tips on how to avoid brain freeze. His best tip is really simple: Just turn the spoon upside down.

Brain freeze happens when something cold touches a bundle of nerves on the top of your mouth, near the back. Those nerves are called your sphenopalatine ganglion, say that five times fast.
