The world has come a long way in the area of helmets over the years, both in how important we understand them to be and in our ability to make technologically advanced and more effective kinds. We now specialize helmets for the specific sport or activity, for age, and of course for size. But that's not all! We have helmets out there that are "green" and made of bamboo, helmets that do nothing but give great head massages, and even ones that will electronically monitor and record impacts and potential head injuries during a football game.

Very, very cool.
