Wearing a helmet is all about impulse, change in momentum and the force of impact. This video illustrates why you should secure your helmet to your head. Thank you very much to Colton and Jean Johnson who said yes when I asked them if I could film myself riding my bike off their dock. Colton also said, â€œIn my 75 years of living, that has got to be the strangest request I have ever received.â€ Thank you also to Chris Palmer and Larry Braak for being my onsite camera operators.
