in this research we want to Survey the effect of any type of consumption pattern (that were mentioned above) on the life expectancy of people and social stability.

So we have three types of personality:
1-Greedy persons: who consume more than their real need,
2-Modest person: who consume equal to their need,
3-Altruist person: who consume less than their real need.

And the environment that is filled by resources randomly and the agents can acquire resources from this environment (based on their personality).
Bellow you can see some of the agent's variables:

1-Wealth: a random number that shows the amount of resources a person has.
2-Real need: a random number, shows the amount of need for staying alive.
3-Estimated need: the need that is estimated by a person in a mental process. It can be more, equal or less than the real need. Every agent gains from resources equal to its estimated need.
4-Efficiency: a random number, is distributed between turtles. It has a threshold. If the number be higher than the threshold, turtle is a useful and efficient person in society and can help to reproduce the resources and its own wealth.

Also, Turtles can reproduce and die. If the wealth become less than a threshold or the age become higher than 85, they will die.
In the ground, each patch has 3 variables:

1-Reserve here: It shows the current amount of reserve on each patch
2-Max reserve: It shows the maximum amount of reserve that each patch can hold.
3-Ind-reserve-grown: It shows the amount of reserve’s growth in each tick.

Also, there are 2 global variables in our model:
1-Gini index reserve: Gini index is a number between 0 and 1, in each tick and these numbers are shown in a graph that indicates the changes of gini index over the time. As the number gets closer to one, it means more inequality in wealth distribution.
2- Lorenz points: It is a graph. The space between the curve and the standard line that shows the equality of wealth distribution among the people of a society. The less the space, the more equality exists.
