195 – Summer Series 4 – Debunking a Bill Gates Conspiracy
Is Bill Gates really trying to decrease the world’s population by 15% using the covid vaccine? Was the gong show that is Microsoft Office just a prelude to mass genocide? What would you do if a friend forwarded you a Ted Talk of Gates claiming exactly that? Would you assume it was a deep fake or edited to misrepresent what he said or is it even more complicated than that. Floris van Vugt joins to unravel the mystery of the billionaire’s bluster and tell us if indeed there are microchips in our vaccines.

194 - Summer Series 3 – PCOS or PMOS
Polycystic Ovarian Syndrome has been renamed Polyendocrine Metabolic Ovarian Syndrome. So seems like a good time to review our previous episode on it as we prep for a formal update on why the name change happened. Also, we hear Danielle’s voice for the first time!! Robyn Flynn joins Chris to talk about polycystic ovarian syndrome. More common than most people realize and with more far-reaching implications than it would initially seem. It can impact fertility, cardiovascular health, and according to Robyn is more painful than childbirth?!? We’re going to have to look into that one.
