From green light go: "What makes a disease a disease? Why isn't aging, a condition which results in the slow decline of the body, considered a disease? It seems so obvious. ... Another reason why people don’t recognize aging as a disease is because 100% of the population suffers from it. We just need one person with perpetual youth to ignite a massive outcry for an aging cure. Finally, we need a new word for the disease. 'Aging' is too confusing. People associate it with children growing, or with becoming wise and experienced. One could then use 'senescence' but that is a biological term. So what then can we use? Senectitudeitis? Enter Senectitudeitis, a disease characterized by: 1) Somatic degeneration, 2) Wrinkling of the skin, 3) Macular degeneration, 4) Muscular degeneration, 5) Sexual decline, 6) Increased risk of Cancer, and 7) the dreaded Gothenburg Syndrome where people come to identify with the disease as being a normal part of life." It wouldn't much matter whether we called aging a disease if not for the FDA, whose unelected and unaccountable bureaucrats will only approve treatments for diseases (when they're willing to take the political risk to approve anything at all, that is), and who do not recognize aging as a disease. In a world without the FDA standing athwart progress to cry "halt!", who would care what we called aging?
