This episode is about mental fitness. I want to share with you my favorite top ten keys for optimal brain health and fitness. We've discovered more about the human brain in the past 20 years than the previous two thousand years. And we know that memory, only one third of it is predetermined by biology and genetics.

But right now, take notes if you need to.
