I have been reading this off and on for some time now, and may as well pitch in, I suppose. Currently closing in on 74 and now dealing with Parkinsons and leukemia. Same damned thing my father turned up with. Hereditary? I am told not, but one has to wonder. NOT looking for sympathy, but I have sometimes thought on finding a community where I might be able to pass on life experience and practical matters I have picked up over my time.
I tried several places via IC.org and was either ignored or refused as, while they would not come out and say it, I was too old. I am not dumb and know what was going on. So, I take a dim view at this juncture of community for the aged. It seemingly does not exist. "Oh, he is just an old scudder and if you ignore him he will go away." That seems to be the pervasive attitude.
So... I shake and jitter my way through the end times and make myself less apparent in permies. Shopping as early as I can when I need to, selling off tools and bits of my life, and spending a lot of time staring off into the middle distance. Seems the best course at this point.
