 During some of these public interviews, Kravinsky argued that should someone be, for instance, on the verge of curing cancer but would die unless Kravinsky were to donate his second kidney, that being the only match in the world, that it would be morally correct to donate the kidney in order that millions of people would be saved.Kravinsky has noted that this admittedly theoretical and highly improbable scenario is the logical extension of someone risking his life by jumping into icy water to save a child, or a soldier cradling a hand grenade to save his buddies.He is mentioned in former President Bill Clinton's book "Giving," and in an article in the December 10, 2008 issue of the Journal of the American Medical Association, The Economics of Health Equity.
