E represents the Existence factors Health, Friendships and Financial Stability.

H represents the Higher Order dimensions of Self-Esteem, Expectations, and Ambitions.

This formula for happiness was worked out by a pair of British researchers. Each person who completes the questions ends up with a rating out of 100. The higher the score, the more happy they are.

"Most people probably don't know what happiness is, they think happiness is perhaps having lots of money or a big car, or a big house. But people who have all these things are not necessarily happier than people who just enjoy their life."

Mr Cohen said the British were expert at making themselves unhappy by focusing on negative things. "We tend to be very obsessed with what is wrong, what is missing and what we have not got, rather than focusing on what we want and getting it. It would be nice to just enjoy your life, because life is a bit short."

The researchers found that different factors were important for the different sexes. Four in ten men said sex made them happy, and three in ten said a victory by a favorite sports team. For seven in ten women happiness was related to being with family, and one in four said losing weight. Romance featured higher for men than women. So did a pay rise and a hobby they enjoyed. Women were more likely to cite sunny weather.

Ingrid Collins, a consultant psychologist at the London Medical Centre, told BBC News Online: "I would be very surprised if people sat down and had to work out whether they were happy or not.

"We can all be happy in a heartbeat if we make the decision to be so."
