Should scientists spend time,money and resources to help people to live 100 years or longer?
In this day and age ,the human society is progressing rapidly on various fronts,there has been a lot of research and development in extending life expectancy, yet in the mean time,several arguments are arisen about whether scientists should spend time, money and resources to help people beat old age.
There are those who feel that scientists should not try to help people beat old age.Most people regard their parents' and relative' life spans, and national life expectancy as benchmarks, holding the view that they are unwilling to slow the aging process for the reason that they do not want to undergo life-extending medical treatments to have their life spans extended. Besides, according to the article”The Demographic and Biomedical Case for Late-Life Interventions in Aging”, aging is commonly considered to be a main risk factor of non-communicable disease.In fact,aged people are facing greater challenges like spiritual and mental stagnation,average health status falls,lacking of progress and achievement, boredom and frailty.If the human lifespan were to be extended, they would have prolonged suffering, place enormous burden on health-care system and cause higher health care costs for society. Research showed that disease cost in the United Kingdom in 2010 was ₤40000 per minutes for dementia and ₤15,000 per minute for heart disease. In addition, extended life spans would have economic impacts on GDP, tax revenue,private pension plans, labour market. Issues would arise regarding the uncertainty between longer life expectancy and economic strategies. Moreover, natural resources influenced by overpopulation which raltive to extended lifespan, which we’re already facing shortages of, will exponentially decrease as well. We would out of fossil fuels and other non-renewable resources.
Others argue that scientists should use technologies to extend life spans. The psychologist Dr. Carstensen mentioned in “Growing Old or Living Long: Take Your Pick” that our lifespan time horizons affect our motivation, behavior, risk taking and cognitive processing.That means the longer life span would probably not only make people look and feel younger, but also including youthful behavioral patterns, people would remain productive longer. Moreover, increased lifespan would provide possibility for people to remain in the labor force longer, have lifelong learning,have more income and saving,minimize financial risk and allow people live healthier and longer lives than predecessors. Last but not least,extended life spans could be one of the most efficient and promising measures to combat disease, have productive and healthy longevity, and reduce health care costs. Because prolonged, chronic illness is a significant driver of medical costs, the large percentage of health care costs today increases the burden on the economy and society. Also,we are faced with the decline in birth rates and an increase in the number of retirees. It is probably better to investing in regenerative medicine,seeking measures to help people live longer life and keeping people young and occupied for as long as possible.
Having considered all the arguments above.I believe anti-aging research that would provide new approach to health promotion,disease prevention and allow people live longer lives deserve to be invested. But the negatives should not be ignored.
