Do you fancy releasing some endorphins to bathe your brain in a vat of well-being? Well, I've found out from the Action for Happiness website that you're more likely to be perked up by giving money away than spending it on yourselves. A bit of further delving around and I discovered a TED talk by one of the people who did the original research. If you have a spare ten minutes, it's well worth a watch.
So the challenge is on. Go forth and spend, spend, spend today. For after all you're worth it!
