You might like to take it with a grain of salt, but a new poll has revealed the ages people start judging you for still wearing skinny jeans, having long hair, or indulging in some favourite pastimes from your younger days.
A survey of 2000 people in the UK asked for their thoughts on the age when certain things become inappropriate.
Prepare to be irritated... here are the results:
• Age 34: stop taking selfies
• Age 36: don't text chat, and you should no longer have a favourite boy band
• Age 38: stop having belly button piercings and tattoos, and do not get drunk in public
• Age 39: don't wear a mini skirt
• Age 40: stop having 'boys' and 'girls' holidays away, and you should no longer go to Ibiza
• Age 42: you should no longer wear a football shirt
• Age 43: stop buying the latest gadgets, and don't wear leggings
• Age 44: you should stop going to nightclubs
• Age 45: at this age, you should stop going to festivals
• Age 46: stop wearing a bikini, and cut your hair shorter
• Age 47: you shouldn't wear skinny jeans, and stop using Twitter
• Age 49: ditch Facebook, and stop wearing trainers
The survey, carried out by Retire Savvy, found that ageism is obviously still alive and well, at least in Britain.
