And all the men and women merely players.
They have their exits and their entrances,
And one man in his time plays many parts,
His acts being seven ages."
This famous quote from William Shakespeare's play "As You Like It" compares the world to a stage, and people to actors playing different roles throughout their lives. It suggests that life is like a performance, where each person has their own unique part to play. The "seven ages" referred to in the quote represent the different stages of human life, from infancy to old age.
