Kids are doing it. Students are doing it. Triathlon athletes are doing it. Chad le Clos is doing it. Heck, even the weavers in my garden are doing it thanks to the birdbath. So why not the elephants? Elephants don't have sweat glands so they stay cool by flapping their ears and using the blood running through their ears like water running through a radiator. They also like to throw water over themselves to stay cool and occasionally they like to swim. And when they do swim they do it properly.
