Do you know what the word “entropy” means? In Webster’s, entropy is defined as, "The degradation of the matter and energy in the universe to an ultimate state of inert uniformity." Put more simply, entropy is the tendency of all matter to fall apart, wear out or disintegrate into the substance from which it came.
In some cases, using material things wears them out faster. Your car, for example, accumulates wear and tear and loses it's value when you put a lot of miles on it. Entropy occurs in the human body in the opposite fashion: It falls apart when it is NOT used. Differently stated, “Use it or lose it.”
