I have had long soaks in the bath that were more stressful. I have been on tropical beaches that were more noisy. After a while I became so detached from reality that I put on my indicator and tried to overtake the car in front. Sounds fine except for one thing. I was already in the outside lane. I came within an inch of hitting the central crash barrier and to this day I wonder what the chap in the car behind was thinking when he saw a three-ton, £250,000 Rolls-Royce indicate, to show the driver wasn't asleep, and then drive off the road.
