The word that came to mind today in regards to my present and ongoing state of being or condition, is "atrophy". It seemed the perfect choice, but then what was that other word, perhaps less common... "entropy"... So, in thinking that I may not have the definition correct in my brain, I went to check. Well...
1 : decrease in size or wasting away of a body part or tissue; also : arrested development or loss of a part or organ incidental to the normal development or life of an animal or plant
2 : a wasting away or progressive decline
2 a : the degradation of the matter and energy in the universe to an ultimate state of inert uniformity b : a process of degradation or running down or a trend to disorder
3 : chaos, disorganization, randomness
In light of my current, rather subtle in appearance, decay and decline in both physical and mental capacity, it would appear that both would be appropriate word choices. Only one thing remains to be said...
"To be or not to be... that is the question."
