Democritus

Democritus was known as "the laughing philosopher" because he advised being cheerful.  He taught that there are smallest indivisible bodies from which everything else is composed, and that these move about in an infinite void.  The atomists held that there are smallest indivisible bodies from which everything else is composed, and that these move about in an infinite void.

Erysichthon

In Greek myths, Erysichthon was king of Thessaly who was punished by the goddess Demeter for cutting down a sacred oak tree. As punishment, he was cursed with insatiable hunger, and no matter how much he ate, he remained ravenous. Some say Erysichthon became a starving beggar and some say he eventually ate himself to death, consumed by his own hunger.
