Our memories tend to become increasingly hazy as we get older, perhaps because our brains naturally start shrinking from the age of 40. The exceptions are what researchers are calling ‘superagers’. These folks are genetically predisposed to retaining a good memory even at an advanced age. To qualify, you have to be older than 80 and perform as well as 55-year-old in memory tests. Using MRI scans, scientists have discovered that their brains shrink by an average of only 0.8 per cent compared to the normal rate of around 2 per cent.
