We got a commitment that 3 million nurses are going to be trained to better identify these signs [of PTSD], because, you know, when these troops come home and they become veterans and they go back into the civilian community, they're not always going through the VA system for medical care. They're going to show up at community hospitals and clinics.

Since we started the Let's Move! initiative, I've been looking for as many ways as possible to help families and kids lead healthier lives.

It's as simple as that. Drink more water.

My happiness is measured against my kids' happiness - when they're in a good place, I feel really good.
