In preparation for a career in academic medicine, I worked as a medical house officer at Columbia-Presbyterian Hospital from 1966 to 1968 and then joined Ira Pastan's laboratory at the National Institutes of Health as a Clinical Associate.

I had learned that science is a rewarding, active process of discovery, not the passive absorption of what others had discovered.

Anyone graduating from medical school in 1966 had first to fulfill military service before launching a career. Fiercely opposed to the Vietnam War, I sought to avoid it through an assignment to the Public Health Service.

The public schools I attended were dominated by athletics and rarely inspiring intellectually, but I enjoyed a small circle of interesting friends despite my ineptitude at team sports and my preference for reading.

George W. Bush was a very bad president. The Iraq war was a big mistake. The U.S.A. needed a political change. I hoped Barack Obama could be a good president, but I'm disappointed. He hasn't done well.

In 1918, when I was 6 or 7 years old, radio was just coming into use in the Great War.

The Medicaid money that right-wingers want to snatch away from Planned Parenthood actually goes toward critical preventative care and treatments for the disadvantaged. So if pro-life activists are genuine in wanting to preserve human lives, waging a war against clinics that help low-income men and women isn't the way to go.

Bob Monkhouse, Galton and Simpson, Spike Milligan and I all started around the same time with an enormous advantage: working to an audience all of whom had shared an awful, common experience - the war.
