Aging

Aging should be good news, since it implies a certain longevity. So if ageing has become a public health issue, it's because of the specific issues of the third age in terms of the health and care of these elderly people in a context where social security contributions are falling while the patients to be covered are increasing, and where ageing has a considerable influence on our behaviour and our exposure to health risks (e.g. air pollution, violence), on our access to services, and so on.
