timeout=0.05;
}

Then for all food items, setstring hungry,#v(strtofloat(#s(hungry))-10); or so.

Note: It is possible under this system to stockpile cleanliness and sleep and food...not necessarily a bad thing, but you probably want to put SOME limits on how negative hungry and dirty and sleepy can be.
