Wearable technology will tell us how well we are sleeping and whether we need to exercise. Sensors in the street will help us avoid traffic jams and find parking. Telemedicine applications will allow physicians to treat patients who are hundreds of miles away.

There is a clear matter that I am not a practicing physician. I have never been a practitioner; everybody has known for decades. I'm a developer of the technology.

My mother, a teacher, encouraged me to use my creativity as an actual way to make a living, and my father, a Mississippi physician, did two things. First, he taught me that all human beings should be treated equally because no one is better than anyone else, and he never pressured me to become a doctor.

The glimpses of human strength and frailty that a physician sees are with me still.

The Yankees, the first mechanicians in the world, are engineers - just as the Italians are musicians and the Germans metaphysicians - by right of birth. Nothing is more natural, therefore, than to perceive them applying their audacious ingenuity to the science of gunnery.

My father left me with his love of Jewish studies and cultural life. To this very day, along with several physicians and scientist colleagues, I take regular periodical lessons taught by a Rabbinical scholar on how the Jewish law views moral and ethical problems related to modern medicine and science.

I think we learn from medicine everywhere that it is, at its heart, a human endeavor, requiring good science but also a limitless curiosity and interest in your fellow human being, and that the physician-patient relationship is key; all else follows from it.

Much of your pain is the bitter potion by which the physician within you heals your sick self.

Ergonomists are not physicians - they are engineers - and their medical theories are controversial. Some of the world's leading medical researchers deny that repetitive motion causes injury.

But for me, a physician, chief medical correspondent for a major network, and women's health expert, the thought of exposing myself to millions of people as someone who'd been completely blindsided by the suicide of my children's father, and by the impact of that suicide on Alex and Chloe and me, was nothing short of terrifying.

We're giving consumers the tools they need to see medical professionals virtually, to Skype with the doctor instead of wait in her office, to self-monitor vital signs, to connect with health-related communities, and to choose physicians based on reliable data about outcomes and cost.

In 2009, UnitedHealth, a leading insurance company, paid $350 million to settle lawsuits brought by the American Medical Association and other physician groups for shortchanging consumers and physicians for medical services outside its preferred network.

I am a medical scientist, not a practical physician.

Medicare is a monopoly: a central-planning bureaucracy grafted onto American health care. It exercises a stranglehold on the health care of all Americans over 65, and on the medical practices of almost all physicians. Medicare decides what is legitimate and what is not: which prices may be charged and which services may be rendered.

Making personalized medicine a reality will require a strong partnership between 23andMe and the physician and medical communities.

I am a medical scientist, not a practical physician. I think it's very upfront. I am a doctor. I have long experience with heart disease.

As a physician and as a pilot, I think it lets me be a pretty good translator having one foot in the medical world and one foot in the flying world. Sometimes when the medical guys come in and speak medical stuff to the pilots, the pilots really don't know what they're saying.

I trained initially as a physical chemist, and then, after becoming interested in biology, I went to medical school and learned how to be a physician. So, I'm a physician scientist.

Everybody who's a physician, who makes vaccines, who wants to find the cure for cancer. Everybody who wants to do any medical good for humankind got the passion for that before he or she was 10.

I would like to promote the concept of a partnership of insurance companies, physicians and hospitals in deploying a basic framework for an electronic medical records system that is affordable.

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.

Certainly when I got to medical school, I had role models of the kind of physicians I wanted to be. I had an uncle who, looking back, was probably not the most-educated physician around, but he carried it off so well.

I studied at the Hebrew University Medical Faculty, graduated, and was an Israel Defense Forces' combat physician on a Navy ship.

As a physician, I know many doctors want to utilize new technology, but they find the cost prohibitive.
