Normal Aging is Not Disease - Adult Health and Wellness

Aging does not inevitably lead to levels of bone density coronary operation, muscle strength, cognitive ability, and memory, sexual desire, and action, physical and social functioning, nor does aging assure levels of blood pressure, cholesterol, and anemia.  How much change there is in any specific body system depends on many factors, such as our fundamental heredity, our lifestyle preserved over the years, our psychological makeup, and the way we've learned to deal with the disappointments, losses, issues, setbacks and normal ups and downs of life.

o Heart and Blood Circulation

The heart needs to work harder as we age and becomes less efficient. There is diminished oxygen extracted from the blood and a decrease in maximum pumping rate. The heart muscle thickens and increases in size while blood vessels tend to stiffen as plaque, and fatty deposits accumulate in blood vessel walls. Because of this, the majority of us experience a gradual decline over time in endurance and energy and many atherosclerosis and heart problems.

o Metabolism, Body Composition, and Body Fat

Gradually declining metabolism together with hormonal changes often leads to diminished muscle tone. Stabilize for many years body fat tends to grow until middle age, and diminish in the elderly. However, as we age, layers of fat tend to redistribute from beneath the skin to surround the organs that are deeper. Women often store fat in the hips and thighs while men tend to develop larger abdomens. Medicine and alcohol are processed more slowly, and reflexes become slower while driving or participating in sports and other activities.

o Brain and Nervous System

Beginning in our thirties, there is a loss and damage of some neurons, blood flow diminishes, brain weight decreases, and there is loss such as memory changes, inability to recall events that are recent or recall names and details. However, the brain adjusts to these changes by increasing the number of connections between cells (synapses) and dendrites and axons (branch-like extensions) that carry messages from the brain. A study in the Journal of Neuropsychology, suggests by enabling older people to call up reserves from the brain's frontal 32, that higher education can prevent cognitive decline. Of man is all about 115-125 years. In mammals, there appears to be a strong correlation between length of life and brain weight.

o Bones

Beginning in our mid-thirties, our bones gradually become less dense and powerful, losing minerals faster than they can be substituted. A loss tends to increase in women after menopause, resulting in increased risk of osteoporosis. By age 65, one in three people reports falls.

o Lungs and Breathing

Beginning in our twenties, lung tissue loses our breathing capacity diminishes and elasticity, rib cage muscles shrink. The lungs become increasingly efficient, as we get older for people that are inactive and less oxygen is received by the body cells.

o Kidneys and Bladder

Kidneys decline in size and function as we age, becoming less efficient at handling dehydration or extracting some medications and wastes from the blood. As bladder capacity declines, urination may be more common, and urinary incontinence may result if the cells atrophy.

o Muscles

Without exercise, muscle mass declines as much as 22 percent for women and 23 percent for men between the ages of 70 and 30. Strong muscles, however, pluck oxygen and nutrients from the blood more efficiently, create work for the heart, and assist the body.

o Skin

As we age, our body decreases its production of collagen, and our oil glands produce less oil, making our skin drier, slowly less elastic, and more wrinkled. We might create age spots or liver spots (brown, yellow, white or red) caused by decreases in melatonin, the buildup of waste products, and growing carcinomas.

o Hair, and Nails

Our hair and fingernails grow more slowly as we age and we also heal from wounds. The hair on the scalp area, and armpits things and the loss of hair pigment cells contribute to gray and eventually white hair. Appearances can be warning signs for serious medical conditions, but nail changes are the first clue. For instance, nail beds may indicate heart disease while rippling and pitting of the nail surface suggests inflammation such as arthritis. White nails may indicate liver disease or anemia, while claws could indicate lung disease.
