When I was walking home yesterday, it began to rain. As it progressively began to rain harder and harder, people began running towards their destinations in order to get there less wet.
However, does running in the rain keep you less wet? Perhaps you are in the rain for not as much time, but then you are hitting more raindrops along the way - horizontally. I suppose that if it was really pouring, you might get wet either way - but in a moderate rain, is it better to walk and hit less raindrops, or run and hit more?
There must be some sort of equation that includes distance, speed, amount of rain and the surface area of the person. I don't know if such a formula could be applied to real life (like measuring the amount of raindrops per second - or knowing your surface area...) but I still think it is something worth pondering.
