I like shows that have some level of intelligence to them. When it's not as predictable, when you don't know what's coming at you.

Medicine has always been my calling.

I really think it would be cowardly to pull back and not challenge the status quo, when the status quo may not be the right way for the field to go.

People say their weight is genetic. But it turns out that people who are overweight don't just have overweight kids. They also have overweight pets. That's not genetic.

The demographic weight of countries such as China and India exercise a massive pressure on our wages and salaries. They have accomplished massive technological advances and the revolution in information technology has reduced the costs of transport.

In 2001, I was being treated for breast cancer, and I was pretty sure I was going to recover.

I'm praying that was my one little dip in the cancer pool. I hope never to have to revisit that, but I learned a lot, I'm cancer free with a bright and hopeful future.

Probably the most important reason we are seeing more cancers than before is because the population is ageing overall. And cancer is an age-related disease.
