Another amazing story of social progress. It’s easy to believe dementia is a bit of an epidemic, I thought that for a while too. But actually the chances of developing dementia in old age have plummeted in recent years. In the 1980s, you had about a 30% chance of developing dementia if you reached the age of 85. That figure is now only 10%. The reason we’re seeing so much dementia is just that we have so many old people now, the huge boomer demographic blip.
