When you're stuck in the rain with no umbrella or raincoat, should you tell yourself "It's just water!", and resign yourself to a brisk walk, or should you sprint your way to the warmth and sweet dryness of home? Walking means you're going to spend more time getting wet, and running means you'll spend less time getting wet, but logic suggests that when you run, you'll also get hit by more raindrops from the side.
