I must be getting old.
welcome aboard the old people's train! On this ride, ya gets to enjoy all kinds of things ya never had when ya wuz a younger stud muffin and some things ya come across now will almost if not kill ya....
Sounds like you caught a for of flu that there is plenty of going around... Not covid.. Just plain old influenza. My daughter caaught some of this stuff a few days ago.. She sounds just like yer description...
Hope ya get to feeling like yer old self real soon! It ain't a lot of fun to feel rotten near death's door but unfortunately for some of us, that's about where we are at this stage of life.
Once yer 70 or over things begin unraveling...
Wishing you good health from here on the rest of this year!
