Who wears a helmet?

aha, well i get the chance to respond: i'm a medical doctor, currently studying for a masters (and possibly a phd). but i still work in hospital regularly. and the reason i brought that up was because ved had earlier referenced this article which kind of implied that all doctors think you shouldn't wear helmets. and that isn't true.
Fair dos, I read this out of context.
