Oh happy days!

Lots of people will be very happy today. According to British psychologist Cliff Arnall, June 19 is the happiest day of 2009.
The scientist created a formula which includes several elements that influence the mood of people.

According to Arnall, the Friday that is closest to the start of the summer is the day that most people are typically happy. It is almost weekend and people realise that their holidays are on its way.

Enjoy!
