 This view handles easily the overdetermination cases that are such a problem for the conventional analysis. When two fires join, two bullets strike simultaneously, two motorcycles scare the same horse, each is a cause of the harm because each is doing its physical work. When one non-mortal wound is inflicted together with a larger, mortal wound and the victim dies of loss of blood, each is a cause of death because each did some of the physical work (loss of blood) leading to death (People v. Lewis).
