Yes, Granpa Dave, I think you are correct. I worked with the HIV/AIDS community for years in Texas. I think his life style is finally catching up.
You have a better eye than most of us re recognizing this end stage of aids.
We live in the Gay Bay area. For decades we have seen this wasting syndrome appear when the aids virus and other pathological invaders are basically destroying the organs of their host’s body. Their brain, eyes and CNS are also targets of the wasting disease.
Often, the wasted ones are gone in a year +- 6 months.
