Many people dream of living long, healthy lives that end peacefully around the age of 100.
Dr. David Agus, cancer expert and author of the New York Times best-seller "The End of Illness," says it can be done.
Agus said on "CBS This Morning" that his medical philosophy is all about prevention.
"I'm a cancer doctor," he said. "I see every week people dying of cancer. And I can't stand it. We need to focus on prevention. We have the tools in our arsenal; We can actually prevent most disease. We just got to use them."
Agus suggests regularity of schedule, statins to prevent inflammation and avoiding vitamins, supplements -- and high heels. Watch the video in the player above for the Agus' full discussion on "CBS This Morning" with Gayle King and Charlie Rose.
