麻豆约拍

Almost one in five people in the UK are aged 65 and older, but even expressing a figure in those terms involves grouping people whose lifestyles and experiences are very different, maybe even three generations apart.

Perhaps it's a shorthand that shows unsophisticated attitudes to anyone aged between 60 and 100+ years old.

A new series for Radio 4 - The Invisible Age - looks at how society views people aged 85 or over, and how this so-called 'fourth age' group sees younger generations who are in denial about the ageing process.

Maybe you have examples of being treated differently or presented with certain choices because someone perceived you as 'old'.

Do you think people treat you differently when you're older?
