I have changed my plans a lot since last week. I am hoping to look at a relation between age/experience and decision making. I am not sure what the outcome will be, but we will find out.

I hope to have certain areas that are unsafe - health is reduced if you are on those patches. Now the decision to set foot on those patches depends on the turtle's age and experience. If the turtle is young, even when it sees something that is dangerous, there is a higher probability that it will make a rash decision and go on the patch nevertheless. For a more experienced turtle, the probability that it will go onto the dangerous patches is lower. With experience, it has learned that its health goes down on dangerous patches, do it should try to avoid them more.

Of course, health gets reduced with old age as well. Younger people have better health. And then at a certain old age, turtles will die. New turtles will be born. So what happens eventually? Are there more young turtles because their health is better because of their age? Or are there going to be more older turtles because they make better decisions and thus can avoid health-reducing situations more?
