This might be good advice although I doubt there are many people, myself included, who would do this.
Mom would say, "My Dad always said, if you're hurting somewhere, put a little red pepper in your eye and you'll forget all about what was bothering you". Yep, I bet there's truth in that statement..
I've inadvertently had something akin to red pepper in the eye. Great for wiping the slate clean in terms of other worldly concerns. But as my daughter, and Mom's granddaughter, would say, "Who does that?" with holy emphasis on the does, pronounced like "duzzzzzzz". LOL.
