Sorry to hear about your friend. That shattered hip thing sounds pretty bad. Legs are one thing, hips and knees are another whole ball game, or so I'm told.

When I hear about things like this it makes me glad that I'm an old enough fart that riding bicycles off cliffs wasn't cool (or even imagined) when I was young enough to be rash enough that I'd have tried it!

By the time I started hearing about people taking old coaster bikes and riding them down "suicide hill" (forerunner of the mountain bikes of today) I'd already taken enough spills on the street on my bicycles and in the dirt on motorcycles to know that it hurt and if I ever rode my bike off a drop it sure as heck wasn't going to be on purpose!

I hope your friend gets better soon!

John
