Happiness is, today, claims maths equation

SMILE – because today is officially the happiest day of 2010.

Psychologist Dr Cliff Arnall used a mathematical formula to demonstrate how human “feelgood factors”, such as enjoying summer evenings outdoors, admiring nature in bloom, the anticipation of upcoming holidays and memories of childhood summers should all peak over the next 24 hours.

To pinpoint today’s date, the happiness guru attached numbers to feelgood factors and ran every day of the year through a mathematical “happiness equation”, with today, June 18, coming out on top.
