       In Britain today, is it possible to tell a person’s class just by looking at him? Physical details alone tell us about health, diet and the type of work a person does. A hundred years ago the working class often looked unhealthy, small and they were either too thin or too fat. The upper classes were often tall, sporting types who were used to a good diet and looked healthy. Today living and working conditions have improved, and such descriptions are no longer true. People are taller now than a hundred years ago. Everyone in Britain today is able to have free medicine, a good die你能数对吗？可得看仔细哟？
