## WHAT IS IT?

This model demonstrates a world where people live to yawn all their lives.

## HOW IT WORKS

The initial total population of this world can be controlled by the "people" slider. This affects how often people yawn as they come into contact with each other.

Everyone in the world will be moving randomly. There will be 3 states of which people could be in. Friends and family are green, strangers are grey and yawning people are red. Some people may go from friends to strangers.

### Population turnover

When the agents die, some will be family, friends and strangers. The agents reproduced will replace those who die as family and friends or as strangers. The rate of reproduction is constant

### Degree of closeness

The degree of emotional closeness can be toggled in the emotional_closeness slider. This controls how many family and friends there are amongst the population of the world. As the agents come into contact, the degree of closeness comes into play, resulting in a state of yawning. Some friends become strangers to one another after a while.

## HOW TO USE IT

The degree of emotional closeness can be toggled in the emotional_closeness slider. This controls how many family and friends there are amongst the population of the world. As the agents come into contact, the degree of closeness comes into play, resulting in a state of yawning. Some friends become strangers to one another after a while.

The setup button resets everything in the population and randomly distributes people and 10 yawning people.

the go button starts the model simulation.

the monitors the percentage of who amongst the population knows each other, and who are strangers.

the plot graph shows the number of people who are yawning in red, not yawning in green, and the total population in blue.
