In our house we don't take ourselves too seriously, and laughter is the best form of unity, I think, in a marriage.

The president [Barack Obama] asked for a commitment of, I think, 100,000 jobs for veterans and military spouses over the next couple of years. And we announced during the tour last week that we have gotten more than 60,000 jobs, and we're well on our way to just crashing that goal out of the water, because what businesses are understanding is that these men and women are some of the most highly trained resources that we have in this country.

When you walk through that door of opportunity you don't slam it shut behind you.

I have never felt more confident in myself, more clear on who I am as a woman. But I am constantly thinking about my own health and making sure that I'm eating right and getting exercise and watching the aches and pains. I want to be this really fly 80-90-year old.

It's not about government telling people what to do. It's about each of us, in our own families, in our own communities, standing up and demanding more for our kids. And it's about companies like Walmart answering that call.

We're our kids' first and best role models. So the first question is, what are you as a mom or a dad doing every day, or every week, to start getting into the good habits?

Ultimately this issue is on us. We're the ones who make the decisions about what our kids eat.
