One William Bolitho, a multi-millionaire entrepreneur, whose leg had to be amputated after a road accident, made an important statement: “The most important thing in life is not to capitalise on your gains. Any fool can do that. The really important thing is to profit from your losses. That requires intelligence, and it makes the difference between a man of sense and a fool”. Similarly a woman who was thrown out of her matrimonial home for having extra-marital relationship, but whose second marriage became a great success and joy, said that: “Exchange and variety give joy, fun and longevity to life”.
Surely, monotony results in boredom and stand-still, because, sustainability and continuity in life demand regular exchange and variety. Exchange should be understood to mean equity and balance in the process of giving and taking, while variety refers to comprehensive exposures to the issues and vagaries of life. In every interaction or relationship, one-sidedness has always been a major cause of disharmony and breakdown. One-sidedness can arise from a deliberate intent to cheat, or ignorance, which places the burden of giving only on one party, while the other becomes a parasite. Unfair deal!
Among other demands on a living being is the necessity or ability to turn liabilities, handicaps or losses into one form of asset or another. Thus individuals are often laden with burdens and cares which they must strive to resolve diligently, in the process of which they learn vital lessons and advance towards greater successes. So, to develop that tenacity to survive in a hostile environment demands that an individual must learn to take some loading tests and pass them without breaking down.
Not only individuals are exposed to loading tests as a means of capacity building, but nature also forces human environments to bear some stress and strains as the means for renewal of energy and regeneration. What we call natural catastrophes are usually necessary processes of repairs and balancing of wreaks and decrepit situations often brought about by humans. For example, lightning discharges between the clouds and the ground during thunderstorms balance the extreme differences in electrical potential which build up between the ground and higher atmospheric layers. Human activities, including illegal refining of chemical substances, cause such imbalances in the atmosphere.
Climate changes and climatic imbalances result from mining and other industrial activities whose disturbances and waste products pollute and endanger the atmosphere and ecosystem. Can crop yields and food production not be affected adversely in areas where the mining activities take place? Even though the effects may not be immediately visible, is it not likely that human health can suffer some risks arising from economic activities? Nature has a way of using ex-change and variety to maintain balance when human activities tend to throw the ecological system into chaos.
We can apply this Exchange and Variety theory in every human situation as a means of correcting social ills and perplexities. Without malice or favour in its application, exchange demands that value should go for an equal value, and variety based on complementarity. Is the political office holder in Nigeria being paid four times what the President of the USA earns (apology to ASUU) in one year, giving services of equivalent value to Nigeria, or a parasite to the country?
Where there is a mis-match in the blending of a variety of substances, there surely would arise some chaos and discomfort. Be it in food intake or in the amalgamation of chemical substances, conditionality must always prevail. Constipation arises in the human stomach when non-complementary food items are consumed, and, in the blending of a variety of substances a condition of near-homogeneities applies. You do not grind onions, tomatoes and stones together! So, the principle of exchange and variety as vital for continuity and sustainability cannot be applied without conditions; neither does nature apply it in an arbitrary manner.
In the farming system, farmlands get exhausted in terms of soil nutrition if same crops are cultivated repeatedly. So, local farmers resort to shifting cultivation while scientific farming would recommend alternation of crops as a way to guarantee or maintain fertility of the soil. Manure and fertilizers are also used to improve soil fertility. We also observe that natural catastrophes rarely occur without warnings to humans as a means of providing opportunity to avert worst dangers. Medical practitioners would say that pains and fever are signs and symptoms of some ailments trying to build up.
Often human beings in their myopic, indolent or complacent attitude allow signs and symptoms of impending disasters to pass without taking appropriate actions. From stomach discomfort, fever and pains; to increasing cases of banditry and terrorism, there is often the tendency to play down on signs and symptoms that are harbingers of catastrophes. The principle of exchange includes giving up something as a restitution, such as giving up a bad habit as an exchange for good health. In all such transactions there must be equity and justice.
Nature abhors and spurns injustices and inequities, and wherever they occur and persist with recalcitrance, then comes appropriate penalty or restitution. A genuine restitution goes with penitence, apology or compensation for the damage done. Similarly the principle of variety as vital element for longevity and sustainability includes the use of complementary additives to boost the energy and health of anything undermined by decrepitude. Healing by magnetism or by herbs is accomplished by infusing matching substances or radiation to give a boost to an ailing health.
In no way can something capable of aggravating a bad situation be considered as a complementary variety. In medical practice matching tests are conducted to ensure appropriate remedies for specific ailments. Thus the habit of consumption of drugs without diagnostic or matching tests is seriously discouraged. But in human relationships we find the union of people who rarely have complementary dispositions. Where the qualities and endowments of one person in marriage do not match with the other, love alone will not bridge the gap.
The woman quoted as saying that “exchange and variety give joy, fun and longevity to life”, after the failure of her first marriage, added that “there is stability and joy when you find a matching partner”. Often it takes several bitter personal experiences and perhaps failures, to be able to appreciate the fact that it takes an indomitable spirit to profit from your losses. Exchange and variety must go with willingness to give and interact justly and sensibly. Put everything to test before embracing them.
