The average adult in UK lies three times in a day and it is mostly about their whereabouts, hours of work and household chores, reveals a new study.
More than a third of Brits lie regularly about their workload to make lives easier, a study of 3,000 adults revealed.
The poll also found that more than one quarter have not been completely honest to their partners about how many people they have had sex with.
Nearly all men said they had exaggerated about the number of women they had slept with while the majority of women confessed to knocking a few notches off their bedposts.
One in four admitted to 'playing down' the seriousness of previous relationships and one in 10 held their hands up to inaccuracies about their current relationship status.
Twentieth Century Fox Home Entertainment carried out the study to mark the DVD release of season two of the Tim Roth drama series 'Lie To Me'.
"It's quite surprising how many people purposely lie. Most of the time it appears they do so to make their lives easier - but getting caught can never be a good experience," the Daily Express quoted a spokesman for Twentieth Century Fox Home Entertainment as saying.
The survey noted that four out of 10 regularly claim falsely to being sick in order to get a day off work while one in 10 confessed to having lied about a relative dying to get time off.
In job applications, a quarter admitted not being entirely accurate about previous experience and many exaggerated qualifications.
A fifth also confessed to making things up on their status updates on social networking sites such as Facebook and Twitter - with a quarter lying about their social life.
The spokesman added, "The results show two thirds think they were not good at lying - but they said they would still do it if it made their lives a bit easier.
"It is staggering to realise that we tell more lies to our loved ones than anyone else. It is scary to think that what we take as the truth could be a complete lie."
