Each individual and collection of individuals of any kind, has an idea of what life and existence are. This is based on empirical observations: when you go to mcdonalds, you are (exist-live) to eat as much as possible, when there are political elections, you are (exist-live) to vote, and to vote only.

There are Units, of tens, of hundreds, of thousands, of millions, of billions, of trillions, of quadrillions, of quinzillions.......etz, etz, etz... Of forms of what you ARE (EXIST-LIVE).
