Aging is not for the faint of heart!
As my wife often tells me, "Getting old ain't for sissies."
Or do I say that to her? I can't quite remember...
I do remember that I never thought I'd be married to a woman her age.
Anyway, Irene, I sympathize. I've been dealing with some age-related health issues myself lately, and they are certainly not conducive to writing. Fortunately I've finally found some relief, although I know that nothing is permanent on Earth.
I look forward to that eternal day when I won't have any health complaints.
