Wear helmets!

This is making the rounds.

As a person who has had his brain on the inside of his skull for twenty-five years and who is in no hurry to reverse that dominant physiological paradigm, I'd also like to point out that the title of the article is "Strange but True", not "Strange but True AND a Good Idea!".

As much as people might lean on the above study to feel better about riding without a helmet, I believe this is all the proof needed to justify wearing one (via Bicycles and Icicles).
