I recently saw an episode of mythbusters where they tested the theory that if you run in the rain you get less wet. Their results turned out to be the exact opposite, they found that running in the rain actually made you more wetter. I'm wondering now, taking into account only the "falling" rain (that is to say, not the water getting on you from you splashing the water beneath your feet, etc.), would something like what was proven also be true for sun rays, for example? At noon with full sunlight, would you take in more amount of sun rays if you ran than if you just walk? We, of course, here would have to say that the system of sun rays would not be a full distributed system, and would have to mimic the fall of rain. I use sun rays as just an example, any other example would suffice.
