This isn't actually only about guitars. In fact, it might just be a little crazy.
I find that as I grow even older (almost impossible at this stage, I know, but it is what it is), I tend to do things in steps that reduce other steps, even when those things require very little energy!
F'rinstance, I find myself paying attention to such things as organizing loading the dishwasher to minimize whatever steps I have to take unloading it, or making sure I have everything I need to take into the studio while working in only one trip. Etc. I just made a martini, which I do at 5:30 3 or 4 times a week, and noticed I was organizing my trips to the refrigerator for olives and vermouth, as well as carrying the items I needed to make the martini in a very energy-conserving way, as opposed to making several trips for ingredients, shaker, glasses, etc.
I don't recall being this efficient with my actions when I was younger.
My theory, which is completely unscientific with a one-person sample size, is that aging reduces my energy level, and as a result, I intuitively plan my steps Ito minimize energy expenditure.
This is both interesting, and a little depressing. Though in a way, it makes perfect sense!
Perhaps I've always been this way, and simply never thought about it before, but I don't think that's the case. I think it might simply be instinctive as human beings get older.
