First World Problems

Not much going on at the moment other than my first world problem of doctor.biopsy(run); causing leg.skin(); to return a null, and
while (healing){
     if (skin == null){
         body.move(false);
         ass.fatten();
     }
}
And then body.status(); throws a PainfulException which I catch and turn into wound.heal(-1); and boolean bleeding = true.
