The first crash helmet I wrote off, was actually an ex-airforce jet helmet. I put a split in the back of it about 75mm long. The second helmet which I destroyed had a flat worn on the top of it. I had gone down the track backwards on the top of my head with my feet in the air at about 70MPH. I could actually see the other bikes coming up behind me. By the time I reached the small ripple in the bitumen, I was sliding on my side - so a dislocated collar bone was the only result. That crash still gives me a bad feeling. However, if you do not die, you are still alive. It was not my own stupidity which caused it. To die while road racing, you have to be very unlucky - the risks are usually all minimised to a tolerable level. In actual fact, I was more likely to die in the course of my employment. There were places I did not go unless it was necessary. When we die, we probably do not know we are dead - other people grieve. Today is my 84th birthday. The corners are arriving quicker.
