Four Biological Explanations Of The Causes Of Death In Late Adulthood

To begin with, individuals in the United States are now living past the age of sixty-five. The average life expectancy of individuals born today in the United States is 78.7 years. This is only made possible because of the improvements in medicine, nutrition, exercise, and lifestyle. Studies show that women can live longer than men. Social factors play a role in why women and men have a gap of life expectancy. These social factors are health attitudes, habits, lifestyles, and occupation. Men are more likely than women to die from most of the leading causes of death in the United States. The causes of death are associated with lifestyle. Furthermore, there are four biological theories that provide intriguing explanations of why we as people age. The four biological theories are evolutionary, cellular clock, free-radical, and hormonal stress. Evolutionary theory of aging is the view that natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults. Cellular block theory is Leonard Hayflick’s theory that cells can divide a maximum

Chronic disease becomes more common in late adulthood. However, arthritis is the most common chronic disorder in late adulthood. Older women are more likely to have arthritis, hypertension, and visual problems. Studies show that nearly sixty percent of the United States adults age sixty-five to seventy-four die of cancer or cardiovascular disease. As previously stated, arthritis is the most common chronic disorder. But many do not know what arthritis is, so what is arthritis? Arthritis is an inflammation of the joints accompanied by pain, stiffness, and movement problems. Arthritis can affect hips, knees, ankles, fingers, and vertebrae. Another chronic condition is osteoporosis. Osteoporosis involves an extensive loss of bone tissue. It is related to deficiencies in calcium, vitamin D, estrogen, and lack of
