Knowing that “dwarf yeast” with longevity mutations in the growth genes (TOR-S6K) could live up to five times longer than normal yeast, and that “dwarf flies and mice” with similar genetic mutations could live up to twice as long as normal mice, in 2006 I started research on the human version of the growth gene known to correlate to record longevity in mice (see fig. 2.2).
