It’s true dogs can be trained to sniff out a wide range of diseases from diabetes to cancer.  I had heard about this years ago from veterinarians that I knew.  This W5 episode that aired November 19  on CTV explained how they do it.

Even more good news about the value of physical activity, strong social ties and sense of purpose as the foundation for thriving well into your 80s and 90s was in this episode.  Yes sign me up for all of this!
