Richard Wiseman is hosting an online experiment studying happiness and well-being:http://www.scienceofhappiness.co.uk/
For anyone who doesn't know, Richard Wiseman is a Professor at the University of Hertfordshire here in the U.K. He is the author of 'Quirkology', 'The Luck Factor' and the recent book '59 Seconds: Think a Little, Change a Lot'.
If you wish, fill out the questions and try the experiment (which lasts about 5 days I think, but only takes less than one minute a day
). You can jump in at the experiment at any time.
Just for anyone who may be interested!
