Patients who are being kept alive by technology and want to end their lives already have a recognized constitutional right to stop any and all medical interventions, from respirators to antibiotics. They do not need physician-assisted suicide or euthanasia.

Childhood vaccines are one of the great triumphs of modern medicine. Indeed, parents whose children are vaccinated no longer have to worry about their child's death or disability from whooping cough, polio, diphtheria, hepatitis, or a host of other infections.

Americans tend to endorse the use of physician-assisted suicide and euthanasia when the question is abstract and hypothetical.

We don't have enough solid organs for transplantation not enough kidneys, livers, hearts, lungs. When you get a liver and you have three people who need it, who should get it? We tried to come up with an ethically defensible answer. Because we have to choose.

By establishing a social policy that keeps physician-assisted suicide and euthanasia illegal but recognizes exceptions, we would adopt the correct moral view: the onus of proving that everything had been tried and that the motivation and rationale were convincing would rest on those who wanted to end a life.

We had a big controversy in the United States when there was a limited number of dialysis machines. In Seattle, they appointed what they called a 'God committee' to choose who should get it, and that committee was eventually abandoned. Society ended up paying the whole bill for dialysis instead of having people make those decisions.

Having been an oncologist and having cared for scores, if not hundreds, of dying patients, when you don't have a treatment that can shrink the tumor and the patient will die, it's a very difficult conversation. It's emotionally draining.

Physician-assisted suicide and euthanasia have been profound ethical issues confronting doctors since the birth of Western medicine, more than 2,000 years ago.

Medical school education and post graduate education emphasize thoroughness.

When my children were growing up, we began every family meal - which included breakfast and dinner every day - with a prayer. We are Jewish and so it was the prayer over bread, when we were having bread, or the catch-all prayer for everything when we weren't.

We're all on a continuous journey to try and fix our mistakes and flaws. And, believe me, I've got plenty of them.

My father always has been attractive because of his energy, warmth, charm, and talent for finding some connection with people from all cultures and walks of life. He rarely observed social formalities and niceties - something he has passed on to his boys.

I'm the son of a pediatrician, and I do believe that the most important resource we have is our kids. And I think the most important thing for America's future is to invest more in our children.

I am not sure precisely why we need to have privacy, but everyone knows for sure that we need to relax and not have to put on our social, outwardly looking face all of the time.
