I am living in the Africa I have always longed for, always felt stirring in my blood.

I've always felt you don't have to be completely detached, emotionally uninvolved to make precise observations. There's nothing wrong with feeling great empathy for your subjects.

Women tend to be more intuitive, or to admit to being intuitive, and maybe the hard science approach isn't so attractive. The way that science is taught is very cold. I would never have become a scientist if I had been taught like that.

It's not a pretty picture, but there are reasons for hope.

I believe that the tragedy [like terror attack] that's caused so much grief and suffering to so many thousands and thousands of people has also served as a call to action, because many people now are re-examining their own value systems, and the churches, temples, mosques and cathedrals are packed to overflowing for the first time in years.

A sense of calm came over me. More and more often I found myself thinking, "This is where I belong. This is what I came into this world to do.

I think I'd like to be remembered as someone who really helped people to have a little humility and realize that we are part of the animal kingdom not separated from it.
