People are getting older – an obvious truth, isn’t it? Everyone ages with the passing of time. But there is another meaning to this unavoidable fact.

Average life expectancy has increased from 26 years 2000 years ago, to 49 years at the beginning of the 20th century and to 76 years in many countries today.

The multitude of third-agers may be new but longevity itself is not. Health, clearly, is the single most important ingredient of a good old age. Research proves that lifestyle is more influential than genes in avoiding age-related health collapse. Most of the vibrant older people are at least conscious of diet and exercise.

It is society that imposes on you a sense that you are old. Older workers are commonly thought to be less adaptable, less capable of learning, less creative and less adept at mastering technology. Yet whenever these assumptions have been tested, they have been found to be wrong. Age, as somebody once said, only matters if you are a cheese. ...
