What is the point of view of William Shakespeare's "All the World's a Stage"?

Modern behavioral scientists will tell you that, although
we assume that people go about their lives taking second by second decisions they
are usually following a pattern based on the "role" they are performing, it's as if they
are following a script they have memorised.

Problems arrise
when they encounter an unexpected situation  which their "role" cannot accommodate. As
an example, consider a person doing their weekly shopping at a supermarket and the fire
alarm sounds. They find it very hard to give up the role of being a shopper and take on
the role of saving their own life and sometimes leave it to
late. 

People who have learned a role which involves
reacting to emergencies, such as a casualty ward nurse or a police officer, react well
to such situations because they are like an actor with two characters to play and are
able to "switch roles" quickly. On the other hand the reaction of most shoppers to a
fire alarm is to carry on being a shopper for a considerable time.  Many people die in
fires because the instinct to continue acting out their role does not allow them to
react quickly enough to the new situation and unfortunatelty some of them die because of
it.

If, for example, an accountant in a factory is given
training as a fire warden, he will quickly change roles if an alarm sounds. If other
employees are asked to particupate in fire "drills" they too will develop the capacity
to change rolls in the event of a fire.  This is not something that people do naturally,
they have to be taught it just like an actor has to learn a new
script.

Shakespear understood that people act out their
lives in a series of roles rather than making decisions about what to do on a second by
second basis. He also added over one hundred new words to
the English language.Quite a clever fellow!
