Each individual is as individual as their fingerprints, and I think that's extraordinary.

Poor countries are being forced to deal with an unprecedented health crisis without the means to tackle it . Governments can only show how seriously they are taking this crisis by taking immediate action to provide four million extra health workers and to grant those in need access to affordable medicines.

I stand on the shoulders of giants that have gone before me, in terms of affording people like myself, women, the access to democracy, the vote, medical treatment, education, everything that I've been given. It's all been earned.

There's so much stigma around HIV/AIDS. It's a challenging issue, and the people that already have been tested and know their status find it very, very hard to disclose their status, to live with that virus, and to even seek out the kind of information they need. This experience of going to South Africa a decade ago really woke me up to the scale of the HIV/AIDS pandemic in sub-Saharan Africa, how it was affecting women and their children. I haven't been able to walk away from it.

I'm a female but I have a masculine side and I'm not going to negate that part of myself.

There's a lot of women's organisations, but they're all working separately. If you get people together, as a collaborative voice, it's strong.

You become really ugly when you become very superficial and self-obsessed.
