Experts have unveiled the 50 most dreaded signs of ageing - which include taking slippers to friends' houses, using the phrase 'in my day' and groaning whilst bending down. Researchers, who polled 2,000 adults of all ages, also placed losing head hair (but gaining it elsewhere) and switching from Radio 1 to Radio 2 on the list.
Listening to the Archers and being unable to name any modern bands and declaring 'It wasn't like that when I was young' also suggest you're not getting any younger.
Other things to look out for include developing a love of sherry, taking a flask of tea on days out and falling asleep in front of the television.
A spokeswoman for Engage Mutual, which conducted the research, said:
''Ageing is a natural process and we can all recognise physical and attitudinal changes in ourselves as we get older."
''What is interesting is the general expectation across age groups that someone in the 'older' age bracket will look and behave in a particular way.
''With an ageing population, and working beyond retirement age becoming the norm, the reality is that many older people are challenging the 'pipe and slippers' stereotype.''
The study found people feel older if their understanding of technology falls by the wayside, either by struggling to use it or in losing touch with more modern inventions such as tablets or the latest digital television options.
Fashion-sense starts to go out of the window as age creeps up - as people choose clothes for comfort over style, start wearing their glasses around their neck and never leave the house without a coat.
People also feel they are leaning towards their later years if they don't know any songs in the top 10, hate noisy pubs and regularly complain about all the rubbish on the television.
Taking a keen interest in gardening, puzzles, crosswords and bird feeding can likewise be indicative of old age.
Knowing what an Opal Fruit is, thinking policemen and doctors look really young, and frequently misplacing items such as glasses or keys also point to someone who is getting on a bit.
Worryingly, 63% of people polled think they are showing many of the signs listed in the top 50, although the majority of those surveyed didn't feel there is a set age at which someone becomes 'old'.
In fact, eight in 10 think you're only as old as you feel, and 76% intend to enjoy their youth for as long as possible.
Although cultural attitudes might encourage us to make light of ageing, 58% of respondents said they are worried about getting old.
Losing your memory (56%), illness (54%) and physical deterioration (54%) worry people most.
But 43% are nervous they'll be lonely, and 52% worry they won't be able to look after themselves.
Four in 10 people are concerned about having no money - indeed, only half have plans in place for a pension, and just 45% have a savings account or retirement fund in place.
The Engage Mutual spokeswoman added:
''We know that there are serious issues as we approach old age, in that we can run out of time to prepare ourselves to meet the potential physical, mental and financial challenges.
''But it doesn't have to be bad news. Some describe the years over 50 as the best in their lives so far.''
