SIR, A recent accident left me unconscious in the middle of the road. I was rescued by a passing cyclist who waited until I came round, then helped me to the verge and sat with me till help arrived to take me to hospital. I have no idea who he was, but hope that he or a friend may read this and pass on my grateful thanks. I would also like to let him know that, contrary to popular opinion, the CT scan showed everything to be normal. Sue Blair (Usk)
