have a helmet? Live in a tornado area? Put it on during tornados then... head injuries are the most common cause of death during tornados. Even bicycle helmets are good!

"It's such a common sense idea that we wonder why it hasn't caught on..."

A review of 50 years of literature found that head injuries were the most common cause of tornado deaths, said Russ Fine, the center's director and one of the co-authors of the report.
