What role did philosophers play in ancient greece

Sometimes in a genuine scientific way, sometimes in mystical ways, but always in an imaginative manner, Greek philosophers approached the big questions of life. Pythagoras considered a charlatan for claiming the doctrine of reincarnation, a half-naked Socrates harassing people on the streets with provocative and unanswerable questions, and Aristotle tutoring great generals: these are examples of how Greek thinkers dared to question traditional conventions and challenge their age's prejudices, sometimes putting their own lives on the line. Greek philosophy began around 600 BCE as an independent cultural genre, and its insights still persist in our times.

The constant presence of diseases or infectious agents within a given geographic area or population group. it may also refer to the usual prevalence of a given disease with such area or group. it includes holoendemic and hyperendemic diseases. a holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). a hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. so probably family history.
