a model of healthy ageing.
Normal ageing is characterised by the fact that as of an intermediate age in life, one begins to experience an increase in diseases, especially degenerative ones.
Exceptional ageing is characteristic of centenarians who are a model of satisfactory ageing, since diseases appear in very late stages of life and they require very little medical care. Their genetic make-up is very important.
Centenarians are an example of life. Not only because of their genes, but also because they follow a healthy lifestyle that leads them to exceptional ageing.
It is also important to take into account that without economic progress and social and healthcare policies, people who reach 65 year of age will not have the same chances of survival.
