Centenarian Longevity

Centenarian longevity is very much based on the internal physiological functioning and health input and output of these individuals. Physiological functioning including the immune system functioning has seen to be maintained and even increased for these longevous human beings. Neutrophilic functioning for fighting infection, and gluthathione and catalyst activity are also maintained through the century years. These results show high correlations between the levels of centenarians, and those of young adults. Genetic-wise, the longer the telomere, the longer the lifespan, due to cell division. Polymorphic genes regulate the immune system and other surrounding structures, maintaining its functions. Furthermore, health-conscious individuals are more likely to maintain a longer life, and reach the century age. This is due to maintenance of functioning by adapting healthy routines throughout their lifetime, even through old age. In conclusion, maintenance of the body and physiological aspects similar to young adults at old ages show a great increase in surviving and living beyond 100 years.

Centenarians are currently at the maximum peak of life longevity in the history of human life. Through the ages, the centenarian population worldwide has increased significantly. In the United States, there are currently 22 centenarians per 100,000 U.S. citizens, and rising (Hausman, 2011, p. 203-209). By 2050, there will be approximately 3.2 million centenarians around the world (Hausman, 2011, p. 203-209). With the increasing numbers, how is this achievable? Research and studies seek to find universal answers in the physiological, genetic and he...
