This famous person said this in the beginning of the book:
All the world's a stage
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. At the first the infant,
Mewling and puking in the nurse's arms.
And then the whining school-boy, with his satchel
And shining morning face, creeping like snail
Unwilling to school.
