Someone once said that all human beings, from the earliest age, are on a slow road to death. By that it was meant that we have a limited lifespan which eventually ends, though many young people don’t seem to realize it. Fact is, everything around us has limitations – beginnings and endings. We are aware of infants being born and of grandparents dying. We also observe animals, plants and insects go through this cycle of life. We speak of the birth and the death of cultures and civilizations, even ideas, trends and fads. We are accustomed to seeing things get old. Clothing and furniture wear out. Automobiles fall apart. Buildings deteriorate and yes, our bodies become wrinkled and old.
To humans, everything is measurable by hours, days and years. At the beginning of our life, time seems eternal, lazy and endless as we enjoy the blessing of youthful vitality and dynamism. As we grow into adulthood, the excitement of careers, marriage, and family life dictate that our minds are pre-occupied with being busy. But then something happens as we reach middle age. We realize that half our life is over and that we have achieved a measure of financial success. But we are also bothered by pains, illness or handicapped by some physical ailment which prevents us from enjoying life as we should. What happened? How did we get to feeling lethargic, achy and physically uninspired?
Part of our problem is lack of exercise. Anaerobic and aerobic are the two basics types which are a big part of the solution. Generally, anaerobic activities build muscles, and aerobic activities strengthen the cardiovascular system. A typical anaerobic exercise is weight lifting. It involves little continuous deep breathing, though it certainly can be done at a rapid pace to encourage faster oxygen intake. One of the benefits of weight-bearing exercise is the fact that it strengthens bones, which is good news to women who tend to lose a lot of calcium and develop osteoporosis.
The kind of exercise vital to building and maintaining our cardiovascular system—the heart, lungs and liver—is aerobic exercises such as jogging and brisk walking. The heart contracts and dilates at an average rate of 72 times a minute, 100,000 times a day, and close to 40 million times a year, and aerobic activity strengthens your heart to do this job efficiently. For some reason though, we believe that the needs of the human body have changed in our modern society. But of course it has not, and in fact, the adage of “use it or lose it” applies even more today as we slave away at sedentary jobs. When muscles are not used they deteriorate, our heart becomes smaller and less efficient, pumping less blood, delivering less oxygen to tissues, and eliminates less waste. In short, we’re in big trouble.
But exercise can turn fat into fitness, fatigue into vitality, and worry about health into energy filled living! So what do we do for exercise? I know for a fact that many people can only walk due to health concerns. Keep in mind that even walking revives tired blood and helps lessen the danger of arterial blockage. Plus, our cells will convert food and oxygen into energy more rapidly, firm up muscles, improve posture, and contribute to a better physical appearance.
Remember, exercise may not add years to your life, but it will add life to your years.
