Constant headlines on the cost of healthcare may give some a pessimistic view of medicine, but Dr. David Agus has another message: This is the best time yet to be alive.

Shelving the insurance talk for a moment, Agus explains in his new book, "The Lucky Years," how advances in science have enabled people to live the healthiest lives possible.

Modern science has revealed the importance of sleep, nutrition and exercise, and the Internet has spread this knowledge to more people than yearly checkups ever could.

"For the first time, we have at our disposal all the information we need to design our own health — and, in turn, the health of the planet," Agus writes. "Put simply, people living in the 21st century are the most fortunate of all previous generations."
