Worse than it appeared:
Chute Armstrong (via stam74490)
It may take some time to understand why Lance Armstrong came apart today, but from this video, one guess is that his body didn't take too kindly to sliding across the pavement so fast. On his back. Not my specialty but doesn't that sort of thing have the potential to shut your body down? Or at least take the edge off? If he's fine by the Pyrenees, then I'd say you have to blame the crash.
