Shakespeare's Seven Ages of Man

The first age shows the infant, just sitting there. Then he vomits out of nowhere. This shows how unpredictable this age can be. Then it shows the schoolboy, crying over the fact that he has to go to school. Until he finds love and he becomes happy and turns into the lover. The soldier shows how any normal person can become a soldier. The justice is shown dealing out the law. Then the old man, who is at the peak of his life and then passes away into insanity.
