Do our bodies simply wear out after too much usage? Or is the schedule of our aging programmed into our DNA? The research on these questions is active and ongoing. Whether the answer is wear ‘n tear, or DNA, or probably a little of both, the reality is that the aging process may be prolonged, but is inexorable. Sooner or later, we all must face it.
Aging is a normal process, and we can observe the effects of aging as its progression impacts all of our various bodily systems. Specifically -
- The Nervous System - The synapses fire at a slower rate which results in reduced balance and coordination. In the brain itself, memory and quick decision-making become less efficient.
- The Musculoskeletal System - These effects are typically noticed first, i.e.
- Loss of muscle tone and mass throughout your body, including the heart muscle and those affecting the bladder,
- Loss of bone density, which often is viewed as a woman’s issue, but does affect older men as well, and
- Reduced flexibility and range of movement as joints wear and tendons loose elasticity.
- The Gastrointestinal System - With aging, metabolism slows down and the digestive process becomes less efficient. Although fewer calories are needed, the system’s ability to extract nutritional value out of the calories that are ingested is diminished.
- The Cardiovascular System - Plaque builds up in the blood vessels, requiring the weakening heart muscle to pump harder. The blood pressure rises while the ability of the blood to absorb oxygen diminishes.
- The Respiratory System - The reduced efficiency of the lungs to supply oxygen starts being felt while climbing stairs or being involved in any energetic activity.
- The Immune System - With the changes to our biochemistry, hormone production diminishes and the immune system begins to atrophy.
However, there are a number of actions that can be taken to delay these changes and diminish their impact on our lives. They are further specified in -
