In this episode, Neil and Gabby discuss how to optimize your everyday habits with author, entrepreneur and professional caveman, John Durant (The Paleo Manifesto and Spartan Fit!). Topics include getting a better shower with no soap, getting a better sleep by simulating a cave environment, lifting your mood by getting in sync with circadian and seasonal rhythms, and designing the ultimate workout based on thousand-year-old rituals. These counter-intuitive practices just might change the way you live your life.

They also talk about how John received a hundred emails from meat-eating, lactose-intolerant, Celiac women after his appearance on The Colbert Report where he described his ideal woman (or as Neil puts it, “tried to impose a plan on nature”), and get in a friendly argument about what makes a long-term relationship work.

In addition to learning about how early humans were the original zombies and how rabies is like Viagra, you will want to buy a lot of things after this episode, so make sure you have a pen and paper ready.
