I can't see the back of my jaw, under my ear, when shaving. And, because I am somewhat lean, to shave there I have tip my head down and stretch the skin downward. This even more moves me out of any position where I can see what I'm doing. So, I was forced to shave there non-visually. Well, I found that switching to other senses than sight didn't slow me down as much as I expected.

Since then, I have also purposefully not used sight when shaving certain regions. I am in no hurry. But, plan on being able to shave entirely from non-visual cues.

Reminds me of learning to type, forcing myself not to look at the keys.
