Must wear helmet while driving a Two-wheeler

Recently, I was driving on highway where I saw a motorcycle affected with road accident. This accident was so fatal that the person driving two-wheeler got seriously injured. He suffered an injury in head because he was not wearing a helmet. Lot of blood was coming out of his head and he was immediately rushed to hospital. He would have avoided this injury, if he was wearing a helmet. It is very easy for any person to buy an motorcycle helmets and it does not cost much. By wearing a helmet any person can save himself or herself from fatal head injuries. Today, people can easily buy authentic helmets from many online stores. Though, it is mandatory under laws to wear helmets; however, still many people do not prefer to wear a helmet while driving a two-wheeler. I want to request every person who drives a two-wheeler must wear a helmet because there is nothing more precious than life in world.
