I've learned with my eyesight on computer screens and the famous "spellcheck" whether we want it or not, can get a guy in real trouble sometimes.... much worse than "milking" vs "milling"
As an aside my wife and I still milk a few by hand and yes the "old" hands just aren't as tight as they used to be especially in the cold. But the grand kids are learning so it'll be a skill that gets passed on. Now in the shop, yeah the "old" hands once again are not what they used to be on the old mills (1928 K&T Horiz and 1942 Wells Index) either. Currently the grand kids are just watching but hopefully some day
