 I'm a sports psychologist who worked for the US Olympic Committee and one of the things that I was talking about here is that one slice of that work which is not the performance side so much as the mental health side and one of the things I was talking about is just the sudden rapid increase in awareness about mental health issues and seeming increase in mental illness rates in young adults and athletes and in the general population. You know there's lots of fascinating interactions between sport and mental health where on one hand sport has been shown and exercise has been shown to really improve mental health. At the same time if an athlete is under recovered you know what we used to call overtraining but now we call under recovery they're not adapting well to the training they're doing that can actually contribute to fatigue, can it contribute to feelings of feeling down it fits a lot of the same criteria as you would for someone who's depressed. It's a mind-body interaction we're not sure exactly where one starts and one stops but we do know that there is an interaction. It's my first time at this conference and I definitely want to return there's a ton of interesting data on injury prevention of injury lots of fascinating speakers from around the world and some really cutting-edge stuff.
