On the logic that people should be discouraged from engaging in lifestyle choices that damage their health - that these things should be "denormalised" - we should take action about jogging. Especially given the burden such inconsiderate activity places on the the NHS.
MRI scans on 40 athletes training for challenging sporting events like triathlons or alpine cycle races showed most had stretched heart muscles.
Although many went on to make a complete recovery after a week, five showed more permanent injuries.
The researchers told the European Heart Journal how these changes might cause heart problems like arrhythmia.
I know the industry - let's call it "Big Gym" - says these are minor considerations and that "endurance training isn't unhealthy" but surely something must be done. And remember that it's not just this increased risk of heart disease, there are over 250,000 admissions to hospital resulting from sports injuries in the UK alone.
Perhaps we should set up Exercise Concern?
