While I've been pretty fortunate in that respect, I've now survived the loss of nearly all my older relatives. My family was never all that large, but grandparents, parents, aunts, uncles, a number of cousins and an older sibling have all passed away, leaving me the oldest survivor of my immediate family. Oddly, I still don't feel "old" in spite of having retired from daily work and being able to take advantage of the occasional "senior discount."
However, it gets closer to home when personal friends are affected. A good friend for many years now, who attended the same university I did (though we had not yet met) and has been fairly close to my husband and me for as long as we've been together (35 years!) has been seriously ill with histoplasmosis. That's a systemic infection by a parasitic fungus if I understand it correctly. It's typically acquired from bat or bird droppings and not very common. Difficult to diagnose and with complex symptoms, the disease can be life-threatening if untreated. He was not diagnosed early, and eventually reached a state of emergency before getting a correct diagnosis. Fortunately, that came just in time and treatment is succeeding, but he has been hospitalized for many weeks and is only now recovering his ability to walk, eat, and perform the tasks of daily life. He is only a couple of years older than I am, and has always been a very active outdoors individual. This is sobering and a bit frightening.
Meanwhile, husband Gary's younger brother has been hospitalized for over two months due to major heart issues. He has had two major heart attacks in the past, and has become so weak that they put him on the waiting list for a heart transplant. This week he received an LVAD, a heart-assist mechanism, in a six hour surgical procedure. His doctors hope this will keep him going until a replacement heart becomes available. He is five or six years younger than I am.
My own younger brother has had both knees and a hip replaced, and has also had back surgery and major heart issues more than once but seems to be continuing a pretty normal life. Fortunately he is married to a very skilled and wise master nurse who can spot issues early and take appropriate action.
So far I've had no big problems and everything seems to be under control. But I begin to wonder if the proverbial sword of Damocles is up there waiting to fall on me.
