(A)
In February, Dr Robert Lefkowitz, a physician and biochemist, published a memoir（回忆录）, called A Funny Thing Happened on the Way to Stockholm: The Adrenaline-Fueled Adventure of an Accidental Scientist. In a recent conversation via video, Lefkowitz said that he wanted his memoir to be "funny, interesting, and easy to understand". In the book, he humorously describes his journey from a cardiologist（心脏病学家）to a biochemist.
Lefkowitz is no stranger to conducting experiments, making discoveries and telling stories. He was awarded the 2012 Nobel Prize in Chemistry with Brian Kobilka. The two scientists were honored for their discoveries on the working of G protein-coupled receptors（G蛋白偶联受体）. The scientists' discoveries could help unlock the mysteries to many diseases.
Lefkowitz's dream of becoming a doctor began when he was eight years old. After his father died of a heart attack, he decided to be a heart doctor. He earned his medical degree at Columbia University.
When asked what qualities contributed the most to his success, Lefkowitz described himself as "reasonably intelligent and creative, hardworking and focused". He added that being funny can also be very good.
Throughout his life, Lefkowitz has made many hard decisions. Before winning the Nobel Prize, he said, he conducted countless experiments, and only 1 in 50 turned out OK. "With difficult decisions I've had to make, I tend to make them with my heart rather than my head," Lefkowitz said. "However, I don't mean that deciding with your heart is always right. In other words, it's all intuition (直觉)."
At age 78, the scientist has no plans for slowing down. "My body and mind are still working," he said. "I want to continue running my lab at Duke University and writing and publishing research papers." For more than 40 years, the Lefkowitz Lab has been a center for research on receptor biology, which is the study of how cells recognize and respond to hormones and drugs.
"You could say I'm like the 'grand old man' of the field," Lefkowitz said, smiling. "Everyone knows me. I enjoy mentoring. I enjoy researching. I enjoy this role."
