Given the possibility of extending healthy, active ageing across our 60s and 70s, what is the potential for maximising the opportunities which arise from the inclusion of several generations in our communities, workplaces, and families? On 28 June 2007, the Policy Foresight Programme convened a seminar on Global Ageing, where participants debated the contention that global ageing is not, in fact, about a world of old people but about a world in which people live longer. This seminar was held at the James Martin Institute, and was done in collaboration with the Oxford Institute of Ageing.
