The world’s oldest mouse, Yoda, turns 136, sort of.
The mutant dwarf mouse (whose cage-mate is Princess Leia) has demonstrated that longevity is possible without extreme dietary restrictions, turning an unheard-of (in mice, anyway) 4 years old.
It’s not exactly crystal clear how 4 years translates into 136, but, as Richard A. Miller, M.D., Ph.D., says, “100-year-old people are much more common than four-year-old mice.”
