Why is this in a fashion forum?
Agree with everything barnburner said. Working as an RN in both ER and ICU for the last four years, I have seen the results of head injuries first hand. It is not pretty. That said, I have seen many patients go on to make a full recovery after a helmeted head injury, when they would have been dead without it. Just wear the helmet. Which is more important, your fashion sense or your brain matter?
