The usual reaction to make polyurethane is exothermic, so this fungus
cannot gain energy by reversing the polymerization. It must decompose
it into less energetic chemicals.


OH–R–OH + OCN–R’–NCO      ==> [–CO–NH–R’-NH–CO–O–R–O–]n

Polyol  + Polyisocyanate  ==>       Polyurethane

Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it." --Brian W. Kernighan
