Ageing is undeniably universal. The Lancet Healthy Longevity is here to argue that having one's later years synonymous with ill health and poor quality of life need not be.

The WHO estimates that between 2015 and 2050, the proportion of those aged 60 years and older in the world's population will almost double from about 12% to 22% (an absolute increase of 900 million to two billion people). In short, we will soon have a world in which there are more older people than children.
