My bro is 5 yrs older than me. He had a bike at 16 going into 6th form just as I was starting at the same school. It was 4 miles from home. Went on the back of him regularly, giving the hand signals (both types !). His first job was in the lab of a paint firm just ½ mile from the school. so it continued a while longer. I recall coming home one evening on a steady RH curve. Suddenly his body went vertical whilst the bike stayed banked. Then I saw the bollard in the middle of the road coming at my head.
