At The Human Edge: The Limits Of Human Physiology And Performance: Guest Dr. Marcus Ranney

Jun 7, 2021 | Podcast


Chris and Neal invite special guest Dr. Marcus Ranney onto the show to discuss his new book, At The Human Edge, as well as his work on the front lines of the COVID-19 pandemic in India.

The book is a non-fiction-based piece of popular science which unravels the amazing adaptive physiological responses that our bodies undergo as we push it to the limits in extreme sports and natural environments. Each chapter captures the history, geography, and physical challenges which our bodies face when we as a species have tried to conquer the great outdoors. From Mt Everest to the South Pole, from a journey to Mars to the bottom of the Mariana trench. Chris and Neal further dive into Dr. Ranney’s strong understanding of human physiology (particularly at the extreme), how the body first deteriorates, then adapts, and finally excels when faced with running a marathon, summiting Everest, or going to Mars.

From sick care to wellbeing, Dr. Marcus Ranney’s career journey over the past two decades have led him from the patient’s bedside to a wider stage as he now creates global impact via systemic change by championing wellbeing.

Completing his Bachelors of Science and Medical degrees from University College Medical School in London his passion for extreme physiology has allowed him to conduct field research across the planet. With expeditions taking him to the sides of Everest, skiing in the Arctic and the European Alps, he has served as a medical officer in the Royal Air Force and at NASA’s Kennedy Space Center.

After practicing clinical medicine in London, in 2010, he made the transition to Mumbai where he has worked within the Healthcare and Life-sciences industry as a Strategic advisor and Investor with a range of MNC and national bellwether firms.

Augmenting his contributions towards planetary health commentary, the Covid-19 pandemic brought Marcus back to the frontlines of medicine as a medical volunteer for his country’s fight against controlling the virus.

A published best selling author, keynote speaker, digital talk show host and public health commentator, he has been a World Economic Forum’s Global Shaper and more recently appointed as a Senior Fellow to the Atlantic Council, working on a project exploring the relationship between the climate crisis and planetary health. A champion of wellbeing, Marcus is a big believer that sustainably improving the lives of billions of people the world over can only be brought about by enhancing the positive aspects of health rather than focusing solely on pathogenesis and disease.

Marcus now divides his energies amongst the three major components of his wellbeing framework – the individual, the team and the system; through various digital ventures and initiatives.

Marcus is a keen athlete and long distance marathon runner, he holds a Guinness World Record for backwards running(!) and thoroughly enjoys being a father to his two young children.
