Cell Phone Use Endaners Boneheads
Research from Harvard states that 2600 people die in each year becauase of cell phone distraction, and 12000 people get injured. Driving while on the phone is risky, but emergency room cases reveal lesser-known dangers of moving while talking. For example, guy on escalator talks on cell phone falls backward, guy talking on cellphone walks directly into street side, guy texting while on a bike and crushes on to the tree, and guy texting walks directly in to telephone pole.
