Add a new rule named “Needs” with the following text:

Each Genetic Engineer has a publicly-tracked number named “Needs” which defaults to 0.

In the rule “Synthesis”, in the Synthesize atomic action insert the following steps just before the step “For each Genetic Engineer with a Status of Injured who is in the Medlab, set their Status to Healthy”:

* For each Genetic Engineer who has a Needs greater than 5, set their Status to Injured.
* For each Genetic Engineer, if they are in the Kitchen or Restrooms, set their Needs to 0, otherwise add 1 to their Needs.
