You should always wear your seatbelt. A young guy died here last week when his car spun out going around a corner and went into a ditch up against a tree. It flipped over before hitting the tree. The driver was hanging outside his window because he wasn't wearing his seatbelt when it flipped over. He was pinned between the car and the tree.
You would like to take comfort in their deaths being quick and painless but in reality they experience everything in slow motion.......and suffocate in their own blood while enduring the pain of multiple broken bones and joint damage as well as ruptured organs.
