In the past, increases in life expectancy were driven by preventing premature death. However, in recent decades, demographic trends demonstrate a dramatic reduction in mortality in older people. The fear is that as lifespan lengthens, so too will the period of illness at its end.
Studies of ageing have brought the realisation that ageing is not programmed but results from a lifelong accumulation of faults and can be affected more easily than was previously thought possible. Postponing damage by reducing exposure or boosting defences will help to delay age related decline, which probably explains why growing numbers of people are reaching old age in better health than in previous generations.
Better nutrition, housing, medical care and working conditions are all likely to have resulted in less accumulation of damage.There is good reason to suppose that this explains the ten-year life span difference between better-off and economically deprived areas of the UK.
Some approach research into ageing from curiosity and others see ageing as an ill that must be abolished. For most people, research gives us scientific insights that can help ensure that the extra years of life we are gaining are as healthy, productive and enjoyable as possible.
Since some of the biological mechanisms implicated in ageing are also related to multiple age-related diseases, we can hope to hit multiple birds with one stone. Significant enhancements to the quality and health of our later years may not be easy to achieve but are at last within our sights.
