The most listened to podcast guest ever on Zestology is back! John Gray on relationships, lockdown, and the one supplement he takes whenever he sees a wrinkle.  DEAL OF THE WEEK: If you want to optimize and biohack and be at your best, it’s worth doing some detailed health testing.  I’ve been using a company that can do it all at home.  InsideTracker is an ultra-personalized performance system that analyzes data from your blood, DNA, lifestyle and fitness tracker to help you optimize your body and reach your health & wellness goals.  So what about my results? One of my blood markers came back well outside range, and now they are helping me to make some detailed changes. That’s great. It’s just something I wouldn’t have known unless I’d taken the test. You can even upload your DNA results to the portal too for extra insights. Visit for a big discount - 25% off, and a cheesy picture of me.
