Join Dr Norman Swan, a multi-award-winning producer, broadcaster, investigative journalist and bestselling author, as he discusses his latest book 'The Brain Cliff'.

What many of us fear, especially as we hit our forties and fifties, is not being as quick of mind. Not remembering as

well as we used to. By our 60s and 70s we worry there's nothing we can do and that we are falling helplessly into an abyss which leads to dementia.

Dr Norman Swan, one of Australia's most trusted doctors, shows us that we've been thinking about brain ageing the wrong way. It doesn't need to be about decline and deficit. It's about how to help our brains adapt, become resilient and maintain cognitive function − and it's much more than what we eat, how we exercise or our genes.

Dr Swan has interviewed people from around the world in their 90s and 100s who still have remarkable cognitive

function. These cognitive super-agers have very different life stories, but it turns out that underneath they're pretty

much the same, with lessons that will help us all in our 40s, 50s, 60s, 70s and beyond.
