I've always tried to make sure that what I do really connects with the broader agenda of what my husband Barack Obama is trying to do.... But I also find that I have to be very passionate myself about the issue to be able to represent it well. One of the big issues that I've talked a lot about...is childhood health, nutrition and obesity.

And let's be clear: It's not enough just to limit ads for foods that aren't healthy. It's also going to be critical to increase marketing for foods that are healthy.

That's where you just have to get creative. There are all these trampoline parks and there's bowling and there's roller skating.

I've always been a closet jock, but when I got married and had kids, that fell by the wayside.

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.

I don't have the stressful job. Barack Obama does.

My happiness is tied to how I feel about myself.
