I read about a survey of 1000 Britons where they discussed the 'cut off' dates for certain things after which time it apparently becomes cringe-worthy to do them. I'll share some of the findings with you.
They reported that the age limit for listening to Radio 1 was 29. I can relate to this, as I think you get to an age when you outgrow it and switch to Radio 2 or your local station, but I will admit to sometimes listening to the charts on a Sunday afternoon.
It also stated that if you're getting a tattoo, get it done before you're 32, and don't wear a baseball cap after this age either. Don't wear one back to front once you're 25.
Don't end emails or texts to strangers with a kiss or use abbreviations like LOL after you're 29 years old - especially if you don't know what they mean (giving the example of David Cameron, who thought LOL meant 'lots of love').
Men apparently shouldn't grow goatee beards once they're 32, nobody should wear very high heels after 34 or kiss in the street once you're 25.
The poll also said you couldn't wear a bikini once you're 48. This particularly annoyed me - Helen Mirren looked fab in hers at 63, Elizabeth Hurley is 49 and Elle Macpherson is 50, so that's obviously nonsense.
Also controversially was not going to music festivals once you're 41. Well, Dolly Parton's 68 and she rocked Glastonbury this year wearing very high heels, breaking at least two of these rules - she was fabulous, and the highlight of the event for me and many others.
So I'm going to follow Dolly's rebellious lead and attend Gretton Music Festival on the August Bank Holiday weekend, possibly wearing a baseball cap if we're blessed with sunshine, and high heels if I want to (but not a bikini!).
I'm just hoping that Jive Honey play their version of Nine to Five so I can sing along...
