There just isn't anything much between you and any hard objects when you ride a motorbike.
The 23 year old son of my best mate has tonight lost his life from an accident that, in a car, would barely have spilled the driver's coffee.
Witnesses say it was at generally low speed. Turning left off a country road onto another road, for reasons the Police have not been able to ascertain, he has ended up going off the road and hit a pole. Even a helmet can't always prevent brain trauma. When they swell up, there's nowhere for the swelling to go. He never regained consciousness, but his family had to watch him losing the battle for a day and a half.
So totally devastated tonight it is beyond comprehension. I watched that kid grow up, took him camping, 4wding, abseiling, and went rock-climbing with him every week for quite a while. He was even quite a budding photographer.

If you ride a motorbike, please take "carefulness" to all new heights. 23 should be the prime of a person's life, not the end of it.
RIP Stewart. Gone so senslessly, and way too early. You're already missed mate.
