At the risk of being a river nazi, this is a claim that's made a lot around here and it's simply not true. Water has absolutely no idea how far away the ocean is, or which is the shortest route. What they take is the easiest route. Often that's also the shortest, but often it's not. A perfect example would be the Nile, which begins its journey less than 500km from the Indian Ocean, but travels almost 7,000km north to the Mediterranean Sea.
