In my third year at medical school in Birmingham, I joined the Air Force as a medical cadet so that I was sponsored to become a doctor.
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.
Now a cholera epidemic was sweeping through Southeast Asia and south Asia in the early 1970s, so I started medical school and I joined a laboratory to work on this.
I first wanted to be a psychiatrist. I decided against that in medical school when I discovered that psychiatrists didn't, in reality, do what they did on TV.
