Aging can be slowed in laboratory rodents by low-calorie diets, and changes in single genes can extend mouse life span by 40 percent or more. Therefore, despite its surface complexity and effects on multiple cells and intercellular systems, aging in mammals might also be retarded by both genetic and nongenetic means. If human aging could be slowed pharmacologically to the extent now possible in rodents, the effect on healthy life expectancy would exceed that of abolishing cancer, cardiovascular disease, and adult-onset diabetes.
Disagreement over the legitimacy of direct sterilization continues within Catholic moral debate, with painful and at times confusing ramifications for Catholic healthcare systems. This paper argues that the medical profession should be construed as a key moral authority in this debate, on two grounds. First, the recent revival of neo-Aristotelianism in moral philosophy as applied to medical ethics has brought out the inherently moral dimensions of the history and current practice of medicine.
The Roman Catholic Church is the single largest denomination in the United States and the one with the most extensive provider stake in health (and related social service) care. As a follow-up to an earlier analysis of the Catholic role in the thwarted health care reform effort of 1993-94, this article looks at the revival of interest in reform and at the rationale behind and strategy of the Catholic Church's current agenda-setting initiative.
