"I feel pleased with the rate of progress of interest in life-extension that is now developing. I am more concerned about the rate of growth of interest in cryonics — since this is the "first aid" which may be necessary for some of us to reach the time when biological aging is no longer a part of normal human life. The decision to include cryonics in a program of life extension requires a great stride beyond the more usual methods of safe and health-conscious living. Cryonics may be an advanced form of medicine that can greatly extend lifespan. Cryonics is not anti-religious or a means to prevent ultimate death. I hope that those who deeply care about their lives and the lives of their loved-ones will increasingly learn to be open to the life-saving potential of cryonics and other practical strategies for survival — and not be distracted by fantasies of physical immortality."
