The smell of chicken soup, candyfloss and sun cream were today revealed among a list of 40 scents which trigger nostalgic childhood memories of school days, holidays and loved ones.
The study of 2,000 adults also found freshly mown grass, candy floss and rain on hot tarmac set the senses harking back to years gone by.
Experts found a waft of lavender, peppermint and were most likely to spark memories of their grandma, while the smell of petrol, musty sheds and Old Spice were likely to prompt memories of granddad.
The research, commissioned by Disneyland Paris to mark the launch of its new attraction Ratatouille - The Adventure on 10 July, also found over half of Brits said the aromas of holiday destinations trigger lasting memories.
Additionally the results showed eight in ten of those polled said a whiff of a certain aroma instantly transports them back to a specific memory - over 70 per cent said those memories were happy ones.
Sensory expert, Professor Barry Smith, who worked with Disneyland Paris said: "More than any other sense, smell can evoke powerful, emotional memories. Whole scenes of people, places and things can be brought back to life by the mere hint of a long forgotten scent.
"The rooms in a friend's house, a boat trip, the sound of a voice, can all be conjured up by smell's power to reproduce the scenes for us.
"The top 40 scents show a wide array of things that awaken our senses and stay with us for the rest of our lives.
"They show the pleasure we take in experiencing smells and the powerful emotions they evoke.
"Happy memories from childhood are bound up with particular smells, and it is the sense of smell that will preserve our link to them.
"Whether it's a seaside holiday, a visit to a fairground, or a sunny walk through a forest, suddenly smelling a particular scent can suddenly take us right back there, re-creating the whole sensory experience.
"Our strongest memories draw on our senses working together, so a multi-sensory experience, such as Ratatouille - The Adventure, that immerses us in a world of not just of sights, sounds and feels, but also smells, lays down vivid memories that can be re-experienced later.''
The influence of childhood memories on us as adults was clear with six in ten saying our early memories affect us powerfully as adults.
Results also showed the smell of chalk, pencil shavings and marker pens puts us right back in the classroom, while the smell of fresh leather has us harking back to slipping our feet into a brand new pair of school shoes.
While the alluring scent of Chanel perfume or a particular hairspray sparks visions of Mum or Grandma getting ready to go out.
Bonfire smoke, a mug of hot Bovril and the smell of a smoky log fire wrap us back in our cold winter nights growing up.
Certain smells really do stick - the over 55s were just as likely to associate the scent of candyfloss with fun childhood attractions as were the under 25s
The power of the senses remains strong despite age - over 55s were just as able to recall memories as the 18-24s
Those in Northern Ireland are most likely to be receptive to a smell reminding them of specific people or places
While those in Scotland are most likely to be able to improve their mood simply by smelling a scent they associate with happiness
People in Yorkshire were most likely to feel the memories and experiences of their early life influences who they are now
Parents in the North West place the biggest importance on ensuring their children have strong positive memories in their early years
However, the ability for smell to provide memories more powerfully than a photo showed a gradual decline with age with over 55s the least able
