74, the mind agrees with you wholeheartedly. The body is not so willing however. I would reiterate the potential danger for any would-be loggers though. A guy died in a logging accident around the corner from me last year, maybe 1/4 mile from my place.
GS, it used to be I could work sun up to sun down and not get tired. I had endless energy and was pretty strong too. Now I find myself taking Ibuprofen afterwards and going to bed early and exhausted when I put in a day of manual labor. I still do more than most my age would even contemplate, but I have to push myself harder than maybe I should. It is tough for me to have something on my to do list that doesn’t get done and so I push myself. Slowing down doesn’t come easy.
