How to the roles of man differ based on the persona's description?

The division of human life into seven stages illustrates the seven ages of man namely: infant, schoolboy, soldier, justice, Pantalone and old age.

The seven ages of man was derived from the medieval philosophy as in the seven deadly sins of man namely; wrath, greed, sloth, pride, lust. envy and gluttony.

The roles of man differs a lot from the description of the seven ages of man. Man has played different roles thus, all men in the world are actors. They only assumed their character's personality by wearing a mask.
