That's fascinating, Anchor. I get intensely itchy on my wrists sometimes around some people. I had not associated it with anything but had never figured out why. I don't have any skin conditions or anything that would cause it and nothing rubbing on my wrists to irritate them.
I love the info about the eyes. I know we inherently know this but it's a good reminder.
And the nape of the neck and small of the back. That's good to know. Lots of good nuggets in your post!
