Britain has seen huge social changes over the course of my lifetime. The world of the 1950s, when I grew up in a modest suburb of Liverpool, has vanished forever. The material standard of living we enjoyed then would nowadays seem to be distinctly substandard. We didn’t have a family car; I shared a bedroom with my older brother; and there was no television set, though we did have a telephone – a rather unfamiliar contraption which we were all too scared to use. There never seemed to be quite enough to eat and we were all rather skinny. There was no problem of obesity in our family, but we didn’t grow particularly tall. Today’s younger generation tower over us.
