Many people have regrets about a lot of things they could have done in their life,for instance, working harder at school, or not exercising enough.
According to the survey, not working harder at school is one of the biggest regrets in life, and wishing we had put more effort in the classroom is the second biggest regret after not saving more money, the Daily Express reported.
The survey also found that having started smoking, not exercising enough and not seeing more of the world were among the top five regrets of people.
But three-fourths of the 2,000 people quizzed by "electronic" cigarette firm Electric Zebra said they did not believe it was possible to live a life without regrets.
On an average, Britons spend 44 minutes every week thinking about things they should have done differently.
The biggest area of regret is love lives (20 percent), family (18 percent), career (16 percent), health and finance (both 14 percent).
But two-thirds said their regrets led them to think more positively and they learnt from their mistakes, the survey found.
