    202 – Ultra-marathons and the danger of long distance running

    A viewer question asks how dangerous marathons and longer races are. Also, there is new data about coronary calcifications in marathon runners.

    197 – Healthcare spending – mo' money mo' problems

    The United States outspends every other country on Earth on healthcare but shockingly does not have the best outcomes and ranks 32nd in terms of life expectancy. Switzerland spends less and does better. Plucky little Canada ranks 22nd in the world. Kim Moon is back to explain why more spending doesn't equal better outcomes and what really drives higher health care costs. Also, a comparative analysis of the US and Canadian healthcare systems: what works and what doesn't in each country.   Become a supporter of our show today either on Patreon or through PayPal!

    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.
