In many developing countries, girls don't go to school. They stay home. They are at the water wells, bringing water back and forth to the village. Or they are doing chores, preparing meals, farming. Some cultures think girls and women shouldn't be educated, and those are very often the places where the treatment of women and girls is the worst.

When you reach out to others in need, when you reach out to the world, you really do have a satisfying life by helping others.

I was so fortunate. My parents lived lives of service. They helped other people, that was their second nature; it came to them so naturally. It wasn't forced. This is their character, and it's a big advantage I have, being raised by people like this, having a secure and stable life, and a lot of love and encouragement.

I think doctors have really come up to speed and understand that more women than men die of heart disease. [But] all the research on heart disease has really been based on men, and needs to be updated with research on women - even very early-stage research is done using male rats!

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?

I was the same way after graduating with a degree in education. I started to teach and I was wondering: do I really know how to teach?

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