How can you expect to solve something as complex as aging when we can't even cure cancer?
For a couple of reasons. We already have some pretty compelling clues as to what causes aging. Enough, in fact, to put our version of a biological "Manhattan Project" to work right now. We even know how to extend average life spans by up to 20 years in many people. Recent giant technology and computational leaps give us the tools today that made unraveling the aging process an unrealistic project just a few years ago. These tools will only get better.
