Welcome to the 5th episode of the six-part series with Professor Sir Muir Gray, talking about what happens to us as we live longer.

In this episode we talk about the changes that occur in the brain and mind as we get older. We discover that the factors affecting the brain and mind are similar to those affecting the body, namely: ageing, fitness, disease and ageism.

Sir Gray was knighted in 2005 for his contributions to the health service, developing Britain’s breast, cervical, maternal and child screening programmes, creating the national library for health, Cochrane collaboration and he is currently the director of the optimal ageing programme.
