Aging and death

Aging is a series of biological changes that follow a natural progression from birth to maturity old age and death. For most people, advancing age is characterized by gray or thinning hair, loss of height, skin wrinkles, and decreased muscle strength. However, an active lifestyle, including both exercise and healthy nutrition, can greatly contribute to achieving long and productive life. Genetics (inherited physical characteristics) also appears to play a role in the process of aging and death. People whose parents or grandparents living in old age seem to have a better chance to live a long life for themselves.

Much has been made in increasing the average life expectancy in humans in many developed countries. This is due largely to the elimination of many diseases of childhood and early adulthood and methods advanced treatment of diseases in the past have led to early death. However, the maximum potential life span of humans appears to remain the same-about 85 years, regardless of efforts to expand it.

Each species has a different normal life. In most species, death occurs shortly after the reproductive phase of life ends. This is obviously not the case in humans. However, women do experience physical when changes are past their childbearing years. The estrogen hormone levels begin to fall, resulting in gradual cessation or stopping of menstruation (The Hormones are chemicals produced by the body that regulates many body functions and monthly menstruation is the shedding of the lining of the uterus [womb] in nonpregnant women.) After menopause (when menstruation ceases and childbearing is no longer possible), women produce less oil of facial skin (leading to wrinkles) and are at higher risk of developing osteoporosis (brittle bones). Men continue to produce almost the same levels of facial oils and therefore less prone to early wrinkles. As we age, our cells become less efficient and our bodies become less able to carry out their normal functions. Sometimes muscles lose strength, hearing and vision become less acute, slow reflexes, decreased lung capacity, and capacity of the heart to pump blood may be affected. In addition, the immune system weakens, making it less able to fight infection and disease.

No theory about how and why older people are able to account for all aspects of aging, but most take one of two approaches: (1) that human beings are genetically programmed to grow old and die, and (2) that the natural attrition causes aging and eventual death. Arguments for the genetic programming quote hormonal control and / or limited cell division (reproduction), as the mechanisms involved in the aging process. A hormonal method focuses on the hypothalamus (at the base of the forebrain), which controls production of growth hormones (which influence growth and development) in the pituitary gland. It is believed that-possibly due to the hormonal action of a clock in the hypothalamus or decreases normal hormonal function, or is more prone to errors over time, leading to aging physiological. Repeated experiments have shown that human cells grown in tissue culture in the laboratory only divide 50 times before dying. (The exceptions are cancer cells that have unlimited growth, and brain and muscle cells do not divide after birth). This suggests a genetic clock which limits the time how many cells can divide. It is believed that with decreasing cell division, as in the elderly, the operation of body, but begins to decrease, resulting in aging and eventual death.

The wear and tear theory of aging and death suggests genes (molecules that contain instructions for the transmission of specific traits from one generation to another) are altered by random mutations (changes in shape) that accumulate over time, gradually leading to aging and disease. Environmental agents such as X-rays, ultraviolet radiation, and chemical toxins, can contribute to this process of mutation. All cells have the ability to repair damaged DNA (deoxyribonucleic acid, the molecular basis of heredity), but when these repair mechanisms fail, mutations accumulate. This bug is also thought to be a factor in cancer development. Two other factors are thought to contribute to aging: (1) damage of the protein of the links of the Cross and (2) the presence of free radicals in the body. The links Cross are bonds that may be defective in proteins such as collagen. Collagen is an important component of connective tissue that provides support organs and blood vessel elasticity. Cross-linking of collagen molecules, changes the shape and function of collagen in a support body and decreases vessel elasticity. Free radicals are normal chemical products resulting from the use of the body of oxygen. However, the accumulation of free radicals, often the result of environmental abuse, can alter cell function, causing damage. Antioxidants like vitamins C and E, block the action of free radicals and therefore believes that retard aging.

Diseases associated with aging, including cancer, cardiovascular (or heart), diabetes mellitus, Alzheimer's and Parkinson's. Diabetes is generally characterized by reduced insulin production. (Insulin is a hormone essential for the metabolism of carbohydrates, sugars and starches). Alzheimer's Disease is a degenerative disease of brain cells that causes progressive loss memory and concentration, and impaired learning and trial. It mainly affects people over 65 years of age. Parkinson's is a debilitating disease in which the muscles become increasingly rigid, tremor-like movements such as walking, is difficult, and involuntary (shivering) to develop.

The death is marked by the end of the flow of blood to transport oxygen to organs and tissues at the end of brain function and organ failure in general. The diagnosis of legally death can occur when breathing and heartbeat have stopped, and when students do not respond to light. Although Alzheimer's disease and AIDS (acquired immunodeficiency syndrome) receive much attention in the press, the two leading causes of death worldwide are heart disease and cancer. Other causes of death include stroke, accidents, infectious diseases, homicide, suicide and euthanasia (which ending the life of a hopelessly ill person for reasons of mercy). The loss of life cans also the result of genetic diseases, infections bacterial and viral infections, drug abuse and alcoholism.

Since you found this site, I assume you are interested in gaining a few extra inches of height. Although (if you’re a mature adult) this may sound like a pipe dream, I assure you that it is easier than you think! We’ve all been taught that height is mostly out of our control, that it’s largely determined by genetics. I’m here to tell you that there is more to the story. Of course our gene pool has a lot to do with ones height, but it is definitely not the only factor. Your state of emotion, your exercise regimen, the food you eat, and the hours you sleep are all factors in height determination. Click here to read the rest of the article: Free Height Enhancement
