Ray Kurzweil has a personal plan for eternal life: don’t die (counting on a low-carb diet, supplements and accelerating medical advances).

“If you combine the knowledge today with the observation that we’re actually on the knee of the curve in terms of acceleration of knowledge and these technologies, and that the full blossoming of the biotech revolution will be here within a couple decades, we can remain healthy through that period and then pick up with that technology,” Kurzweil said. “In every different aspect of the aging and disease process we have ideas for how to get them under control. I believe we’ll do that within a couple of decades.”

Backup plan: cryonic suspension and reanimation in about 50 years.
