Abstract
Although there is nothing new about ageing it is only in comparatively recent times that large numbers of people have survived to reach old age. Havighurst, at a meeting on Leisure and the 3rd. Age held in Dubrovnik in May 1972 estimated that two- thirds of those who have reached the age of 65 in the last 2,000 years are alive today. This gives some idea of the current explosion of old age. In the United Kingdom about 15% of the population are over the age of 65 years. Most European countries have similar figures while other developed countries such as the United States, Australia and New Zealand have aged populations which approach 10% of the total population. Even in the underdeveloped countries the population is beginning to show signs of ageing and many of these have more than 5% over the age of 65 years.
