"Because none of the currently used systems satisfy all ethical requirements for just allocation, we propose an alternative: the complete lives system. This system incorporates five principles: youngest-first, prognosis, save the most lives, lottery, and instrumental value. … When implemented, the complete lives system produces a priority curve on which individuals aged between roughly 15 and 40 years get the most substantial chance, whereas the youngest and oldest people get chances that are attenuated … the complete lives system is least vulnerable to corruption. Age can be established quickly and accurately from identity documents. Prognosis allocation encourages physicians to improve patients’ health, unlike the perverse incentives to sicken patients or misrepresent health that the sickest-first allocation creates"
