Mnemonic

You're climbing Mount Everest. There is a huge blizzard raging outside. It's cold. Freezing cold. You're sitting in your tent, curled into a ball, clutching your legs with your two hands. As the cold air rushes through the walls of your tent your body shudders and you suddenly let out a loud groan. You're going to freeze to death here. You just know it.
