I don't believe in regretting - one should try to move on. My mum was good at that. She was deeply in love with my father, and he died when I was nine. She remarried, and her second husband died, too. I saw the grieving process she went through. My mother had this way of moving on. It was a fine trait.

Childhood is not dead. Children were worse off when we were hunter-gatherers; they were threatened in medieval times and exploited during the Industrial Revolution. Was it any better in the time of Charles Kingsley or Charles Dickens?

IVF is very commercial. The people doing it are among the best-paid in medicine: they charge a lot per treatment and it's not in their interest to make it more effective. Having people fail means that they come back again.

There aren't that many female role models in science. There are a couple of women, but mostly you've got Neil deGrasse Tyson, Richard Dawkins, Lawrence Krauss - they're all guys. Bill Nye the Science Guy. I love that guy, but it's all guys.

A wise woman recognizes when her life is out of balance and summons the courage to act to correct it, she knows the meaning of true generosity, happiness is the reward for a life lived in harmony, with a courage and grace.
