A mass that can choose a case from a condition in an environment of possibilities in a concrete slice of time , is basic form living .every environement have some rules.( the more complex form of living can produce baby)
so Conditions is basic blocks of life.
a computer software can handle conditions and ifs ,so it is living in its world of possibilities(inside computer).
there are 3 level of living:
1- choosing a case in a condition
2- REPRODUCTION
3- growing

mathematicaly speaking, we can make a very little world for example:
w : the world ,containing numbers and conditions (<,>,=)
v1 : a living EXISTENT which can contaion a numeric value ,named variable v1.
v2 : another living EXISTENT which can contaion a numeric value ,named variable v2.
rule1 :in our world v1 and v2 have a turn to choose a value for themself consiquently.

the v1 and v2 simply are living in the world w.
