I think that very much of this list is illness-related, as well as age-related.
Tinnitus, if you are unfortunate enough to have it, is constant. You mostly overcome it by increasing the volume. I think it may cause the loss of directional location through sound, also.
You sit to put on socks when you used to stand - because you can no longer feel your feet, reach them or trust your balance.
I watched my father’s failing health and eventual death and the mark that it left on me was the desire to age as gracefully as possible. Age is more sudden than we would like to accept, but the correct acceptance of new limitations is, I think, the key to graceful aging.
I agree, 100% with your post… That is my goal, to find a way to suffer the indignities of aging with humor (where possible) and Grace. I am on a journey to find Christ, and it is my hope that will assist me in reaching my goal as I expect it will… :-)
