Dr. Sanjay Gupta Won't Take Surgeon General Job

"This is more about my family and my surgical career," Gupta told CNN's "Larry King Live."

The neurosurgeon said he would likely have had to give up practicing had he taken the job as the nation's top doctor.

In addition, the 39-year-old and his wife are expecting their third daughter any time, and the government job would have meant long periods away from his family, he said.

"I think, for me, it really came down to a sense of timing more than anything else," he said. "I just didn't feel I should do that now."
