We're throwing back to our days of advanced math + physics, how Christian wooed Annabelle by sharing intellectual articles, and why you shouldn't let the little things slide in your relationship.

Back in the day, Christian shared a Ted Talk with Annabelle about the mathematics of love and now we've turned it into a podcast because it's the secret to why we "don't fight." Here's what we covered:

* How to mathematically avoid divorce (and the biggest predictor of it according to research)

* What the negativity threshold is and why it's vital to keeping your relationship healthy

* Why how you fight matters more than how much you fight
