Ep. 197: How to Extend Your Lifespan

A recent report showed that Canada’s national life expectancy dropped for the third year in a row—now sitting at an average of 81.3 years. Why are experts calling this decline a historical change? How does your own life expectancy compare, and how can you make tweaks in your routine to help you increase your lifespan and your healthspan?

Here, Dr. Peter Nord is joined by Dr. Doug Manuel, MD, (pictured above) director of the Big Life Lab at the Ottawa Hospital Research Institute and expert in preventive medicine. The two docs explore the implications of a shorter national life expectancy on your life, and the most important things you can do to avoid becoming part of that statistic.
