Do you get more scared as you get older? I’m increasingly worried by the prospect of accidental death or serious injury. Whenever I used to hear of an acquaintance being killed or injured, I once thought, “Poor them!” I still think that but now, shamingly, I very quickly think, “It could have been me.” For 30 years, I biked round London at night, without lights, in a dark suit. Now I always wear a hi-vis jacket, even in full daylight, and sport two rear lights and a front light. Martin Amis said he never thought about dying until he was 40; after turning 40, he thought about little else. I’m 47.
