Physics is an important and often overlooked subject; sure, most of us have a pretty good idea of how matter works. Things that go up (usually) come down. Things that go fast can really hurt if they hit you. And things that are big are generally hard to stop once they get moving. You don't need to be a theoretical physicist to understand these basic principles and apply them to everyday life.

And, when you don't, the results can be downright disastrous. One south African trucker learned this basic fact of life the hard way when he decided against slowing down atop an infamous hill in South Africa. Our cameraman comments on the major f**k-up he sees unfolding before him and follows the truck -- right up to the fateful climax.

While it's hard to say if he saw it coming -- the cameraman remains rather tight-lipped about this matter -- it's certain that there's a lesson to be learned for anyone on the road.
