Twentysomethings may have the sharpest minds but over-70s have a superior way with words

If you want to impress your children with your mental prowess, you might want to give escape rooms a miss and pull out the scrabble board instead. Twentysomethings may have the sharpest minds -- but over-70s have a superior way with words, the Great British Intelligence Test has revealed. The BBC's online test -- developed in tandem with neuroscientists from Imperial College London -- has been taken by more than 250,000 people from across the UK. Researchers found that our ability to solve problems appears to peak in our twenties -- and then declines steadily as we get older. As a result, the experts say that forty-year-old adults have the same problem solving capacities as their twelve-year-old children.
