Why shouldn't organ donors be given priority over non-donors in the complicated calculus of who lives and who dies? "It impresses me as a more fair allocation of a scarce resource," said Emerson, a 53-year-old Indianapolis attorney who had already committed to donating his organs before he joined LifeSharers. According to a statement on the LifeSharers Web site, although UNOS does not endorse LifeSharers' principles, it allows donors to designate who gets their organ.
