There's a great new podcast, called Happy: Tiny Investigations into Happiness & the Good Life. But, I'll admit, I'm biased: I'm the producer. But, really, it's good!

It's ambitiously shooting for something like: 99% Invisible meets This American Life (but on the subject of happiness).
Sometimes Happy will focus on ideas, sometimes science will be our guide. Other times, it will be stories about people following their dreams, like the first episode on Hugh Oliver, which you can listen to here:
