Our ability to form strong emotional bonds with one another is arguably one of the most defining traits of our species.  Back in the day, strong ties provided us with safety in numbers - helping us to protect our feeble, bipedal young from predators. Nowadays they simply just make us feel good. So good in fact, that feeling included by our peers is not only great for our mental well being but for our physical health too. In this series-concluding episode, Rick and Brian get to the bottom of why our relationships are so important and wrap up proceedings by looking back on each topic covered - Awareness, Focus, Positivity and Connection - and how they interlink.  Featuring: Prof. David Clark
