'Biological Theory of Aging\r'

'Biological Theory of senescence Tick tock, tick tock, whats that sound? accord to this theory, its your biological era, ticking away at a predetermined rate. This theory says that DNA, the cadres hereditary material, holds the key to your planned demise from solar day wiz. While this aging theory appears fatalistic on the surface, remember that biology is not destiny. You cant change your genes, but you can decompress the march of time with better take in habits and regular exercise. Your be affirms hormones that help grade myriad functions, including growth and behavior, reproduction, and resistant function.In your youth, hormone production is high, but as you constrict older, hormone levels drop off, causing declines in the organic structures ability to repair itself and to keep functioning in top form. Working cells produce bollocks up. Over time, cells make more(prenominal) waste than they can possibly get unloose of, which whitethorn wreak havoc on their ab ility to function and slowly wizard to their death . Lipofuscion, or age pigment, is one of the waste products found primarily in some nerve and internality-muscle cells. Lipofuscin binds fat and proteins in concert in the cells.It accumulates over time and may interfere with cell function. The protein collagen is at the heart of this theory. Collagen, akin to the frames glue, is one of the most general proteins making up the skin, bones, ligaments, and tendons. When were young, collagen is pliable. But with age, collagen becomes more rigid, and it shrinks. Thats why your skin is less rubber band than before (Alston, 2008). Aesthetics aside, cross-linking may freeze out the transport of nutrients into cells as well as obstruct waste-product removal. poverty-stricken radicals atomic number 18 destructive marauders fluid your torso, ready to pounce on full-blooded cells. They are produced as part of the millions of chemic reactions your body performs to sustain behavior (Wa rd, 2012). Your body also makes them in response to environmental toxins much(prenominal)(prenominal) as excessive come ins of open sunlight and smoking. Free radicals oxidize your cells (think corrode metal). As unbalanced, volatile oxygen molecules, they yield way healthy cells to make themselves more stable. Free radicals destroy or alter DNA, the cells communicable blueprint, and disrupt many other cell functions.Free radicals may kill cells as a result of their marauding, or they may give rise to mutant cells that can result to chronic conditions including cancer and heart disease. Fortunately, the body maintains a sophisticated defense remains against free radicals. Unfortunately, our defenses wane with time, and cell malign ensues (Ward, 2012). This theory could also be called The uptake It and Lose It Theory. The idea is that use, and overuse, of your organs pushes them to the scepter of destruction.A poor diet, too much intoxicant and cigarette smoking are sce ne to accelerate natural offend and tear. With age, the body is less able to repair itself. How does wear and tear occur? Free radicals, which put down cellular damage, may be culpable. akin to the wear and tear idea, this theory says you are born with a certain amount of energy. If you live â€Å"fast,” you die young, because you use up your energy reserves sooner. â€Å"Laid-back people,” who mystify from less stress and take life easier, would live longer should this theory fold up correct (Ward 2012).A strong immune governing body is your bodys most important defense against germs and toxins. clear cells engulf and destroy potential pests such as bacteria and viruses. And they manufacture antibodies, the â€Å"soldiers” that police the bloodstream, attacking and disarming any content they dont recognize as the bodys own. Problem is, the immune system becomes less efficient with time, and fewer antibodies are produced, increasing your infection risk. Whats more, the body may turn on itself by producing antibodies that destroy its own tissue.When that happens, autoimmune disease, such as lupus and rheumatoid arthritis, is the result (Alston, 2008). Although we lock away do not completely hear the process of aging, we do know quite an a lot about it. sometimes it may be time for the clock to just get new batteries or perhaps the clock has stood the test time and became an antique.
