Thousands of people in the world are a hundred years old－or more and certain parts of the world are famous for the long lives of their inhabitants: the Vilacamba Valley in Ecuador, and the home of the Hunzas in the Himalayas．
Why do so many people live to a healthy old age in certain parts of the world? What is the secret of their long lives? Three things seem to be very important: fresh air, fresh food and a simple way of life．People work near their homes in the clean mountain air instead of travelling long distances to work by bus, car or train．They do not sit all day in busy offices or factories, but work hard outdoors in the fields．They take more exercise and eat less food than people in the cities of the West．For years the Hunzas of the Himalayas did not need policemen, lawyers or doctors．There was no crime, no divorce and not much illness in their society． They were a happy, peaceful people, famous all over India for their long, healthy lives．
Do you want to live to a hundred years old? Here are some rules for success．Firstly, choose your parents and grandparents carefully．If they lived or live to a good old age, so will you．Secondly, live in the right place．Thirdly, choose the right kind of job．Doctors, dentists and bus-drivers die young．Farmers, priests and orchestral conductors live much longer．If you are in the wrong kind of job, you can still improve your way of life．
An old man in the Caucasus was talking about his past life．"I was young then," he said, as he described his 87th year．His secret was: "Think young and stay young．" An old woman from Missouri, USA, gave this advice, "Drink a little whisky and some warm beer every day．" An English lady just said, "Take a cold bath every morning．" The shortest, simplest piece of advice came from Mr．Jim Chapman, aged 103．"Just keep breathing," he told reporters．
