What hemet does the best job in preventing brain injury?

An article appears in today's on line edition of the New York Times discussing the continued debate on what is the best standard to determine the safety of motorcycle helmets and their ability to prevent or reduce the severity of brain damage.

The artlcle is entitled, Sorting Out Differences in Helmet Standards and reviews the debate between Federal Department of Transportation helmet standards, the Snell Standard and an new safety standard being introduced by Snell.

While this is all very confusing, one thing is clear, any helmet is better than no helmet at all and all states need to impose helmet requirements for motorcycle riders as well as those riding bicycles, roller-blading, skate boarding, skiing and ice skating,
