There are different levels of sickness
Lime
Lime green
Brown
Red
and Non existent
The blue are completely healthy
The lime are sick
The lime green are a bit more sick
The brown are severely sicl
The red are deadly sick
When one sickness touches somone else that person becomes that level of sickness
But if a red touches somebody then that person dies
But if they all social distance and don't touch anyone nobody will become sick and die
It is hard in the begininng and they don't social distance, but later in the model they do start to social distance a bit.
