Morganti treats runners for injuries, and she says they’re the worst patients. “The treatment is to stop running,” she says. “They won’t. They don’t want to. A lot of the behavior is not unlike the patients we have who are seeking drugs. It’s really similar. It’s an addiction.”
A drug addiction. And that’s where we return to David Raichlen’s experiment.
