Wear Your Helmets!

I used to fly down hills on a mountain bike without a helmet. Had several crashes and my head narrowly avoiding rocks, cactus, and trees. Except for the occasional memory lapses and walking into walls, I'm fine!

It's amazing that 3 inches of foam and plastic can save your life.

I wear mine when I'm riding in NYC traffic, but don't know if it'll help much if I get run over by a cab or bus...
