Men prefer the smell of petrol and frying bacon to that of a newborn baby, a study has found.
Top of the list was freshly-baked bread followed by clean sheets and freshly mown grass.
Fish and chips, roast dinner and fresh coffee also made the list as did fresh air after rainfall.
Women picked bread, grass and clean sheets followed by fresh flowers and vanilla as their favourites with vomit, body odour and public toilets the worst smells.
Around the house rubbish bins, wet dogs, cigarettes and smelly feet came top.
It also emerged that nine out of ten women believe a nice scent has the ability to change their mood.
The study was carried out by www.OnePoll.com, which surveyed 4,000 Brits.
Stephen Weller, Director of Communications at the International Fragrance Association, said: ''Scent has always played an important part in our everyday life - wherever we go, we are surrounded by different smells, some good and some bad.
Dr. Pamela Dalton, who has a PhD in experimental psychology and trained as a cognitive and sensory psychologist, also commented on the results: ''We may all react differently to any particular scent.
''Smell has the power to revive the past and transport us to a happy time or place or remind us of a special person, evoking feelings of nostalgia and comfort.
''The link between scent and memory is very strong, and how we react to different smells is therefore very unique and dependent on who we are as individuals and our past experiences.''
Other things to make the men's top 20 include lavender, apple and blackberry crumble in the oven and a freshly lit match.
Women's top 20 also featured vanilla in fifth place, freshly ground coffee in sixth and rainfall in seventh.
Their top ten was completed by chocolate, babies and lavender.
The study also found that 92 per cent of women said smells make them happy.
Memories of happy childhoods were named as the main reason Brits were fond of pleasant smells, followed by 'feeling at home' and delicious food.
While women claim certain smells put a smile on their face because they're homely, or reminds them of someone they love, blokes prefer exciting and invigorating aromas.
And eight out of ten men said smells made them happy.
With nearly half (48 per cent) of blokes admitting to using scent in the home, with it helping a quarter of them relax, wind down or create the right mood.
More than nine in 10 men (94 per cent) even went as far as to say their home smelling nice was important.
The survey found catching a whiff of a partner's aftershave on a passer-by raises a smile for eight in 10 Brits.
But nearly two thirds wouldn't dare tell a friend or work colleague they smelt bad.
Yet 54 per cent per cent of blokes WOULD, compared to just three in 10 women.
And Christmas tree pine needles, bonfires and cinnamon emerged as the smells Brits associate with winter.
