In the natural world, what is the probably the most efficient traveler?
Probably a fish like a salmon
Not a horse. Not a bird like a pigeon. And a mouse is surprisingly inefficient
And not a human
But
Put us on a #bicycle and it seems we have the entire natural world beat *and* all of our machines 馃槻
