Since the early 1900's American life expectancy has climbed from about 50 to 80 years. Advances in the biological sciences are now entering a new era with the developement of drugs and therapies to combat common diseases with aging. It may now even be possible to expand our life expectancy by decades. Dr. Katch will talk about ways to increase life expectancy and do so at a healthy level.
