"I've cycled to work almost daily for 4 years during which I've been hit twice. Although bruised and very much shaken up, I was not seriously injured primarily because I wore a helmet. In one instance, I landed on my head so hard that the helmet cracked. The consequences of following the advice of this Dr. is at best a cracked head and a visit to A&E. The only downside - another £20 for a new helmet although I view this as one of the best purchases in my life. I won't sit here and lecture others to wear helmets - in this country it is a personal choice. However, I believe it is irresponsible for a doctor to actively encourage people not take easy and inexpensive measures to protect themselves from serious head injury."
