I will never be without a full face helmet for two reasons:
1. I do believe they help prevent serious injury or death far more than being the cause. No one has ever shown me any data to prove otherwise.
2. All active duty members of the military riding motorcycles are required by regulations to wear helmets at all times, whether riding on or off post, as well as full fingered gloves, over the ankle shoes or boots, and wrist to ankle clothing. As a retired soldier subject to recall, I choose to remain subject to that regulation as well.
