The 2006 U.S. Consumer Product Safety Commission reported that an estimated 151,000 bicyclists visited the ER due to head injuries in one year alone -- and helmets can reduce head injury by up to 85 percent. Keep yourself safe (and set an important example for your kids) by donning a well-fitting helmet each and every time you ride. Your helmet should sit level to the ground and not be able to move more than an inch in any direction when fastened.
For help with today’s challenge, learn how to ride a bike -- safely.
