Carl Honoré believes we're all missing out by stereotyping older people as "over the hill". He argues for recognition of the positive sides of ageing, and thinks everyone would benefit from more inter-generational mixing. "Spending time with people of different ages makes us happier – and less ageist. After all, nothing shoots down stereotypes more than getting to know the people being stereotyped."
