The Science of Brain Ageing + How to Increase Your Cognitive Power | Dr Norman Swan
1 hr 9 min
Most senior leaders have a year in mind when they will finally stop. House paid off, kids launched, a few rounds of golf a week. Dr Norman Swan thinks that date deserves a much harder look. The research he’s been reading points to retirement as a likely cause of cognitive decline, with the same drop showing up across country after country. And the plan most of us have for filling the time, more family, a caravan trip, a few series to binge, doesn’t give the brain the load it needs. Swan, the ABC’s best-known health broadcaster, joined Andrew live in Sydney for Florence Guild to talk about his book The Brain Cliff and the super-agers who stay sharp into their nineties and beyond. What they share is surprising, and it starts with how they handle stress.
