Unbidden, the memory of reading about the medical condition known as "hyponatremia" popped into my head last night--it's a dangerous medical condition caused by over-hydrating (usually done by marathon runners who are over-eager to prevent dehydration) where the sodium levels in the blood drop too far. It can lead to all sorts of unpleasant symptoms, and can even be fatal.
It got me thinking about marathons in general, and I had to wonder, "How did all this get started?" I mean, yes, we've all heard the legend about the Battle of Marathon, and the Greek soldier who ran all the way from Marathon to Athens, proclaimed the Athenian victory, then keeled over dead.
What I wanna know is, who looked down at the guy's corpse and said, "I bet I could beat his time"?
