How can a human possibly be going so fast or so high? And also, who was it that first had the thought they should even do such a thing?

To attempt to answer those questions, I thought I'd dive

into the physics and the history of some of the most mind-blowing Olympic sports, luge, bobsled, and

skeleton. And just to make sure we're all on the same page here, a brief differentiation of the

three. So bobsled is the one from cool runnings, where athletes are in an almost car-looking

vehicle that they have to push before they all jump in it and ride down the course. In Luge, the
