Research just out has identified today, Friday 23 June, as the happiest day of the year. "The study suggested the warm weather, outdoor activities, and time spent with friends and relatives were the vital ingredients for a happy life," says the BBC. Apparently England's World Cup performances are also a contributory factor, though I'm not so sure about that myself.
Cliff Arnall, the University of Cardiff psychologist who came up with the report, said: "Whether it is a sunny day, a childhood memory, or something as effortless as eating a delicious ice cream, I wanted my formula to prove the key to happiness can really be that simple."
Funny coincidence that he should mention ice cream so prominently, given that the research was commissioned by, er, Wall's ice cream.
