only time in the last 20 years I agreed w Wifey for us both to not wear helmets, she crashed twice & fell the 2nd time breaking her wrist. 1st thing the ER doc asked her when inspecting the wrist: "were you wearing a helmet"

she broke her wrist but she was lucky (that she didn't hit her head)

we'll never do that again

oh, and I just watched the surveillance video of actor George Clooney hinting a Mercedes head on, where his helmeted head broke the car's windshield ... that guy is lucky to be alive, walking & talking
