What we now know is that the genetic factors that influence your longevity are not genes that measure out the passage of time; the reason we age and die is because, as we live our lives, our bodies accumulate a great variety of small faults in the cells, and the molecules that make up the cells in our body — so aging is driven by this accumulation of faults. The genes that influence longevity are those that influence how well the body copes with damage, how aggressive our repair mechanisms are; they’re genes that regulate the house-keeping and maintenance and repair.
