What is the psychology that allows Vonn to keep crashing so hard and getting back up?It's not psychology, it's physiology. It's a psychoactive immune response. Every time she gets hurt- she gets a dopamine reward from her brainstem. More injury=More immune response. Surgery and rehab will do the same thing.
It's all fun and games now, but at this rate it will surely kill her.
Update- yeah Tiger Woods seems like the perfect companion. No impulse control problems there...
