Is it just ME..???

I feel your pain, I'm 71, and my brain, (never mind my body), is not quite as sharp as it once was.
Ever since I went down with Covid in late fall of 22; my body is different. My Muscles often lack strength or endurance; to do the things I used to do, as a matter of course.
Lately, I have been giving my 40yo son the heavy end of whatever I need to move or carry. Occasionally my fingers are more clumsy than I remember; they just feel thick.
My brain seems to have survived Ok......... altho, sometimes I wonder.
But otherwise in good health.

But yeah, brakeline fittings have to be lined up dead straight.
I get it.. I deal with and feel the effects of head and neck cancer, (and the treatments) everyday...with everything I do.
I went from a stout 195 lbs. down to 147 lbs. Right now I hover around 160 lbs.. My strength, endurance and time have suffered. I can't work under a vehicle without getting the worst charlie horse in my neck every few minutes.. that slows me down for sure.
I'll stop complaining..lol Most of us are going to have some sort of physical issue.. We're not teenagers anymore, that's for sure..! I am happy I've been able to do what I have with this project... It's my first and last one..! Just hoping I can drive it someday.
