I don't want to hear about someone dying because they weren't wearing a helmet. Wearing a helmet doesn't prevent head injuries it increases your chances of surviving a crash MUCH HIGHER.
Yesterday I my friend fell on a road he has ridden 100 time over. I don't know the details of the crash, all i know is i had to steal my moms car and call in a helicopter to save his life. I held my friends head and watched him bleed profusely from the back of his head. If there wasn't a helicopter to rush him to the hospital his chances of survival were slim and if he wore a helmet he would have never needed the helicopter.
Just wear a helmet, it really does save lives
