Santa may have delivered a new bicycle to your child for Christmas. Don't let your child use an old helmet. There may be unseen cracks that may make that old helmet unsafe for use. You should consider getting a new bicycle helmet to go with that new bike. The Journal of the American Medical Association reported that safety researchers, who studied emergency room statistics, found helmets reduce the risk of head or brain injury in bicycle accidents by 69 to 74 percent. They think the overall drop in risk is at least 80 percent when considering people who don't go to the hospital after a bike accident. Don't become a statistic. Get your child a new helmet today.
