Seatbelts will save your life!

I just got to class and found that one of my fellow classmates was in a crash similar to the one I was in. The only difference between our two crashes was that I was wearing my seatbelt and he wasnt. My crash involved me driving at about 70 mph and hitting a guardrail which is made of metal, I escaped the crash completely unscathed and honestly had no signs or reasons to go to the hospital other than to be on the safe side. His crash involved him driving a truck at only 45 mph and he now has a piece of his skull missing as well as having to get his head shaved so they could apply the stitches to the places which needed them on his head. I am not god and maybe I just got lucky but I cant help but wonder was there someone watching over me that night or was it the seatbelt that completely stopped me from being injured. Either way I am not and will not drive myself or with anyone else that is not wearing their seatbelt. It is just not worth taking the chance... WEAR IT!!!
