Over 120 Aboriginal communities run their own health services - some have been doing so for 30 years. They struggle with difficult medical problems. They also try to deal with counselling, stolen generations issues, family relationships, violence, suicide prevention.

Because I am not formally trained in the medical sciences, I can bring in new ideas to AIDS research and the cross-fertilization of ideas from different fields could be a valuable contribution to finding the cure for AIDS.

If I'm pushed, I'd also have to admit I don't like people with allergies. They just annoy me. There seems to be something far too self-centred about it. 'No thanks, I'm allergic.' Why not just say 'No thanks'? I wasn't asking for your medical history, I was just passing around the nuts. Trying to be friendly, that's all.

Haiti is always talking about decentralization and nothing has been so obvious, perhaps a weakness, as the centralized nature of Haitian society as being revealed by the earthquake. I mean, they lost all these medical training programs because they didn't have them anywhere else.

It's interesting when people make comments about celebrities' weight gain or lack of weight gain as if they're a medical professional that's treating that celebrity. Like, 'This doctor does not treat Jessica Simpson, but thinks her weight is unhealthy.' If you don't treat her, then how do you know?

No one wants to go back to a situation where, if you have a pre-existing medical condition, you, you can be deprived of coverage. No one wants to go back to a situation where, if you get seriously ill, you can get thrown off your insurance. Seniors don't want to go back to paying more for their prescription drugs.

There is an element of anger among women who've been raped. There's certainly a major element of humiliation. But it really does seem like a medical condition of shock and horror.

Yet it looks as if the thing we use to solve our problems with is the source of our problems. It's like going to the doctor and having him make you ill. In fact, in 20% of medical cases we do apparently have that going on. But in the case of thought, its far over 20%.

Abortion is inherently different from other medical procedures because no other procedure involves the purposeful termination of a potential life.
