Ralph Waldo Emerson once said that "common sense is genius dressed in working cloths." I don't know if there is a more basic safety device than a seatbelt, so by that logic I guess you can say that you're a genius if you wear your seatbelt. That might be a stretch but in contrast, you can't be very smart if you choose not to wear your seatbelt.
There's no good reason why someone can't put on their seatbelt. If it's because it's not comfortable, buy a sleeve for it. I know I'd rather pay five dollars for comfortable safety than know everyone in my family will be in tears at my funeral. If it's because you want to live on the edge, try skydiving. If it's because you just don't want to, then you should really gain some knowledge about how a seatbelt can save your life.
According to the National Highway Traffic and Safety Administration, "In 2008, 64% of the passenger vehicle occupants ages 13 to 15 and 21 to 34 killed in traffic crashes were not using restraints." That percentage is disgusting. The fact that so many people could have been spared from injury, even death, but made the choice not to protect themselves is appalling. It is so easy to click in a seatbelt and help protect yourself. In fact I don't think it's possible to make it any easier. Whether you forget or you have your own reason not to wear your seatbelt, it's for your own good, for the good of anyone who cares for you, that you buckle up. Find a way to remember, think about how important your reason really is. Chances are that any reason for not wearing a seatbelt is a lot less important than their life.
Did you know that "among passenger vehicle occupants over the age of 4, seatbelts saved an estimated 13,250 lives" over the span of 1 year. If all the passengers had been wearing seatbelts, "17,402 lives could have been saved." Have you hear that if you wear your seatbelt you "reduce the risk of fatal injury to front-seat passenger car occupants...
