...the life which is best for men, both separately, as individuals, and in the mass, as states, is the life which has virtue sufficiently supported by material resources to facilitate participation in the actions that virtue calls for.
AristotleThe male has more teeth than the female in mankind, and sheep and goats, and swine. This has not been observed in other animals. Those persons which have the greatest number of teeth are the longest lived; those which have them widely separated, smaller, and more scattered, are generally more short lived.
Aristotle
