You are correct - this is interesting. I run, and in the last 2 years my only medical visits are for bacterial pneumonia (non-flu related, just appeared to be really bad luck) and a stress fracture in my knee from ‘overtraining’. The stress fracture involved 3 visits with an orthopedic surgeon, an x-ray, and an MRI. Wonder what the tradeoff is there for my lifetime medical expenses if I wasn’t running?
