To celebrate five years of The Happiness Lab, Dr Laurie has picked out the five episodes she loves the most. And this is a special one - Nerd Out! The Happiness of Being a Fan.

Really love a TV show; a boyband; a sci fi movie; or a celebrity? We're often too embarrassed to admit adoring some things for fear that we'll be seen as frivolous or childish - but we may be missing out on the happiness benefits that geeking out can bring.

Dr Laurie explores the joy of fandom with Benedict Cumberbatch obsessive Tabitha Carvan, YA author Jennifer Lynn Barnes and Star Trek actor (and geek-vangelist) Wil Wheaton.

Happiness Lab is five years old. To mark our birthday, Dr Laurie has picked her favorite five episodes from the archive. The show Why Nostalgia Ain't So Rosy was certainly a memorable one for her.

Actor Rob Lowe LOVES the 1980s. And who can blame him? He was one of the most famous men on the planet. But, as he tells Dr Laurie, he's careful not to wallow in nostalgia for the music, fashions and events of his youth too much - and happiness science backs him up on this.

Research suggests that our memories of the past can be very selective and highly unreliable - causing us to misremember events and cast them in a rosy glow. Sadly, this also causes us to make very bad decisions about what will make us happy in the future.

To mark the podcast's fifth birthday, Dr Laurie is revisiting some of her favorite episodes. And this show - Working Your Way to Happiness - has a special place in her heart.

Marty kills rats... but if you asked him what his job is he'd say it was "solving problems" and "helping people". How we view our work can contribute greatly to our daily levels of happiness - far more than money or status.

Dr Laurie examines how we all came to ignore the importance of job satisfaction and hears from Professor Amy Wrzesniewski about "job crafting" - the reframing skill that happy people like Marty use to see their careers as more than just a way to make money.
