I said it then in some of the posts last year and the year before about using magic markers sharpening chains... y'all are gonna get old some day and eat crow. Sooner or later, everyone succumbs to Presleyopia (that is the inability to see Elvis up close).
My advice: when you get into your 40s, get several pairs of reading glasses. They sell them in 3 packs at Costco. Keep them all over. In tgeh truck, in the shop, in the garage, next to the computer. I also have several pairs in different ranges. Some higher power ones are for reading, some are for intermediate distance stuff like working on chainsaw on the bench, and some are for internet reading and typing like I have on now. You get a different range of focus with different glasses.
Now Gary, its time for a margurita
