Series in which Michio Kaku goes on an extraordinary exploration of the world in search of time. How long would you like to live? 100 years? What about 200 or even 1,000? Amazingly it could happen, as Kaku finds out. The greatest power that time holds over us is that it is both limited and yet so precious. But new discoveries in nature and genetic research are suggesting that we have the potential for a massive extension of human life, and one scientist believes that children already alive today could become effectively immortal. But what would immortality really mean? Culturally, we are shaped by the knowledge that our time is limited, both as people and societies. Death surrounds us in our art, monuments, and music. Change our relationship with death and everything else changes too.
