When people ride bikes without helmets, they are risking their very lives. Although helmets can be uncomfortable, the short-term discomfort is well worth the avoidance of the long-term pain that an accident can bring or the consequences of an unexpected death.
When people ride without helmets, they dramatically increase their chances of receiving severe injuries if there is an accident. Such injuries can be disfiguring, or they can lead to brain damage and/or death. Besides the physical risks associated with riding without a helmet, there is another danger, too. Many states and counties have laws that prohibit the operation of a motorcycle without wearing a DOT approved helmet. Fines for breaking these laws can be several hundred dollars, and repeated offenses could cause you to lose your license or even end up in jail.
It is best to avoid all of that trouble and reduce your risk of injury by simply wearing a helmet. Find one that fits and is as comfortable as possible, and always put it on before you get on your bike.
P/S : Buy a brand new helmet like me. An 'Arc' brand helmet.Comfort and stylish.
