Great images, especially the stock photo of the doctor with the family member!

But seriously, it's better to be safe than sorry. My head had a run-in with the support structure for a bridge a few years ago. I don't know how, since I lost about 30 minutes of memory and suffered a level 3 concussion (severe head trauma with loss of consciousness and at least 15 minutes of memory loss), and I was wearing a brand new (two months old) Bell helmet at the time. The helmet was destroyed beyond recognition, of course, and if I hadn't been wearing it, it would have been my head destroyed beyond recognition. Moral of the story-BEST $100 I EVER SPENT IN MY LIFE!! If the thing's five or seven years old, thank it for the memories, put it to pasture, and pony up the cash for a new helmet. My interval is three seasons, then replace (unless I crash it sooner, then I replace immediately).
