Finally grabbed a grinder again yesterday

I know what you're feeling I am also 68 soon to be 69. My best days come in at 60 to 70 degrees. Knees hurt hands hurt like hell back makes me sit a lot. So, I do everything slow and steady, But I get it done. I've been working on my 66 Barracuda for 3 years and its almost done. I can't wait to take it out for its first run down the road.
