That is your legacy on this Earth when you leave this Earth: how many hearts you touched.

Laura Bush went on national television during the week of my father's funeral and spoke out against embryonic stem cell research, pointing out that where Alzheimer's is concerned, we don't have proof that stem-cell treatment would be effective.

My father's body lies in a stone tomb high on a hill. People walk by, pause, think their own thoughts about him and move on, back to their own lives. I can never move on. He is everywhere.

I don't think it's an accident who our parents are; I believe we choose them. So maybe I chose my parents in order to effect change.

My father, for his part, was not a man to begrudge anyone a divergent opinion; he'd have been fine if I had written some articles disagreeing with his policies, or even given interviews, as long as I was respectful and civil.

it ultimately doesn't matter which disease gnaws away at the body - it looks the same. The flesh surrenders, grows exhausted, and the eyes ask why.

I think we can work through a lot of political and international problems, but what really frightens me is what's happening environmentally.
