I've been studying this for more than 20 years. This is not 'alternative medicine.' We are inducing a fever, as though we were giving the patient malaria or a bad case of the flu.

We're not hitting home runs. We're not curing people, but we're extending lives.

Both strategies are important. We know this works. We are often dealing with critically ill patients, and anything that enables them to live longer, even a matter of months, is what we hope to achieve.

You see the worst of the worst when you are in medicine. We all thought the worst, initially. You live with your mortality.

Cystoscopies gastroscopies biopsies. They can do three or four of those and make five or six hundred dollars in a single day but we get nothing when we use our time to understand the lives of our patients.

They've got all kinds of scientific studies, good peer-reviewed medicine, that shows how important particulate matter is to causing morbidity and mortality. I have even seen some scientific evidence that it causes asthma, not just exacerbation of it.
