Longer life expectancy is often discussed as an issue for older people, but ageing societies are likely to reshape life for every generation.
As birth rates fall and populations grow older in many countries, economies and public institutions are being forced to adapt.
Workplaces may need to support longer careers, retraining and more flexible transitions into retirement. Healthcare systems face rising demand for chronic care and long-term support.
At the same time, family structures are changing. More adults may find themselves supporting both children and ageing parents simultaneously.
Technology companies are responding with tools for independent living, remote health monitoring and assisted care.
Yet ageing is not only a challenge. Longer healthier lives can also mean extended careers, deeper experience and new opportunities for education or entrepreneurship later in life.
Experts say the key issue is not ageing itself, but whether societies redesign systems built for younger demographic structures.
The future of ageing will therefore be about more than later life — it will influence work, family, housing and public finance across society.
