Among over-50s, 43 percent felt they had not experienced middle age yet. Nearly three quarters said that there was less of a divide between the age groups than in the past, with improved health care seen as the main reason.
Eight in ten people polled agreed that the term 'middle age' is much harder to define now than it used to be. The same number thinks it is mostly a state of mind.
Around 84 percent people said that if you think of yourself as old, you will naturally start to feel old. Illness and memory loss were named as top threats people fear most in growing old, according to the research commissioned by Benenden Health.
The research also came up with a familiar top 40 signs of approaching middle age. People listed frustration with modern technology as the top sign of ageing, followed by a tendency not to have a clue what young people are talking about.
Aching joints, needing naps, hating noisy pubs, not knowing what is in the charts and choosing clothes for comfort over style were also on the list.
"Britons are happily skipping over traditional notions of middle age. It's a term with less significance and is no longer a numerical milestone. A variety of factors are involved, including more active lifestyles," said Paul Keenan, communications chief at Benenden Health.
"It's clear that what age you are has become less important in determining how young you feel. Being old appears to be a state of mind rather than being a specific age," Keenan said.
