Leo, Cute but not provable. Perhaps I should have said their probability of dying over a time interval remains constant. For example actuarial tables will tell you a 30 year old human will have about one chance in a thousand of dying within the next year while a hundred year old human will have about one chance in two of dying in the next year. This is not the case for naked mole rats. While no other rats are known to live to be 30, a thirty year old naked mole rat has the same probability of dying in the next year as a three year naked mole rat.
