Friday's topic is: Ageing: An Unprecedented Challenge. Throughout the world, people are living longer than at any other time in history. This is a triumph for humanity. Soon, the world will also have more older men and women than children. The process of ageing, which starts before we are born, is inevitable for us all, whether we are a man or a woman, rich or poor, young or old. But everyone ages differently. The World Health Organization is looking forward to your stories on how to make this world of 7 billion people a better place for ageing well into old age and for older persons.
