A review of the literature and a study of 52 patients of the 80+ age group confirmed the premise that good health habits have a positive effect on the quantity and quality of life. Not all persons can live beyond 80, but those who do can lead a better life if they live properly. A profile of these 52 subjects aged 80 or older revealed that they were of average size or thin, and of a happy temperament; they ate well and regularly, slept adequately, avoided excessive amounts of alcohol, did not smoke, used drugs sparingly, and led an active life, physically and mentally. Also, it was apparent that the rugged elderly can withstand the impact of a major illness or a surgical operation with associated anesthesia. The following factors are important for longevity: 1) pick the right grandparents, 2) keep active physically and mentally, 3) eat properly, 4) stay thin, 5) drink alcohol moderately if at all, and 6) do not smoke.
对文献的回顾以及对52名80岁以上患者的研究证实了这样一个前提，即良好的健康习惯对生活的数量和质量有积极影响。并非所有人都能活到80岁以上，但那些活到80岁以上的人，如果生活方式得当，就能过上更好的生活。对这52名80岁及以上受试者的概况分析显示，他们身材中等或偏瘦，性格开朗；饮食良好且规律，睡眠充足，避免过量饮酒，不吸烟，谨慎使用药物，并且在身体和精神上都过着积极的生活。此外，很明显，身体硬朗的老年人能够承受重大疾病或手术及相关麻醉的影响。以下因素对长寿很重要：1）选对祖父母；2）保持身体和精神活跃；3）饮食得当；4）保持苗条；5）如果要饮酒，适度饮用；6）不吸烟。
