Jenna's traveled with me; they've both traveled with their dad. This is the only time they've been old enough in all of their dad's campaigns to really be involved in.

Giving homeless children the chance to be educated, giving them this ticket to their futures, is so wonderful. They will have the chance to not repeat the suffering of their childhoods in their own families. They can build secure and safe lives for themselves and their children.

When I heard that heart disease kills more women than all cancers combined - when I heard that, I knew. The other thing that's very important is that heart disease...is preventable. There are some specific lifestyle changes that women can make: losing weight, not smoking, exercising, eating healthy foods. Knowing the risk factors: high blood pressure, high cholesterol, diabetes, [being] overweight. And if you have heart disease in your family, you should see your doctor. Because this disease is preventable.

It's a huge advantage to have parents who read to you. And it's an advantage that lasts a lifetime.

If you take the burden of health care, of diseases off the backs of some other countries, it gives them a chance to use their own very limited resources in ways that help their people. And also there's a hopelessness associated with deadly diseases, that if that can be alleviated, people can build their own economies in their own countries and they'll be less reliant on the developed world for help.

The English language lacks the words 'to mourn an absence.' For the loss of a parent, grandparent, spouse, child or friend we have all manner of words and phrases, some helpful, some not. Still, we are conditioned to say something, even if it is only 'I am sorry for your loss.' But for an absence, for someone who was never there at all, we are wordless to capture that particular emptiness. For those who deeply want children and are denied them, those missing babies hover like silent, ephemeral shadows over their lives. Who can describe the feel of a tiny hand that is never held?

It's really important for boys to have a father around, or a grandfather, or an uncle - a man they can really relate to who loves them, and who they know loves them.
