What is your master plan for extending the human lifespan?
SENS is an acronym. S-E-N-S. It stands for Strategies for Engineered Negligible Senescence. It is my overall grand plan for seriously fixing aging. It consists of a seven point plan that is based on the categorization of aging and aging damage into seven major molecular and cellular phenomena: The loss of cells, the gain of too many cells, the accumulation of mutations in our chromosomes, the accumulation of mutations in the mitochondria, the accumulation of indigestible molecules inside the cell, the accumulation of indigestible molecules outside and especially in between the cells, and the stiffening of long lived structures made of proteins that need to be elastic in order to work. Those seven things can all, in principle, be repaired or reversed, or in a couple of cases made harmless, obviated, by technology that either already almost exists or it's at least very foreseeable that we can describe in a lot of detail. That's why I'm optimistic about the forseeablility of real anti-aging medicines, so to speak, and therefore the eventual and robust extension of healthy life spans.
