I heard Jonathan Weiner speak last week about his book Long for This World: The Strange Science of Immortality. Basically, there are researchers currently searching for the keys not just to longer life, but to complete immortality. The most notable among them is Aubrey de Grey, who not only believes that immortality is possible, but that the first person to live to be over 1,000 years old has already been born. Them’s fightin’ words. But the idea of living for even a few hundred years, let alone a thousand or eternity, raises some very serious questions about the limitations of our planet and our minds.

I was inspired to make this video about it. I hope you enjoy.
