This video shows a comparative between the monetary value of using adequate protection while riding a bike versus not using any protective devices. The damage one can cause to the body by not using driving protection is incredibly big and economically speaking is almost 20600 times higher than using the right safety artefacts. Please value your life before you go out without protection, remember anything can happen on the road and no one is exempt from suffering a crash or an accident. Very good advice from my father by the way.
