When theory tells what is possible

Nobody should be shocked if we say that a human body is a system! Now, if we consider a human being as a system and therefore as a combinatorial game, we can easily assume that if the human is hit by any illness, we can assume that the illness is a player and has played the first turn. As doctors, if we want to cure the patient, we need to play in our turn and there will of course be a reaction of the illness which will be considered as another round and so on. In the end, what we target is winning the game so that the illness will lose! As an assumption we take that the illness plays the best as possible and is therefore the strongest adversary we can have. Now, we must know to which game we are going to play because depending on the game, the strategy will change and this will be, in our referential, the essential role of the doctor: which game to play to be the most efficient?
