Impressing mapping. It's definitely acupuncture / acupressure
   type of thing. There's validity to some of it. I don't know
   about the theory-as-stated, but then again, I don't know about
   the theory-as-stated for a lot of things that also happen to
   work. Deep spot between the thumb and index finger at the web
   near the bone? Works. There's a spot that gets tender two inches
   up and to the left above the nipple (men have easier access to
   the spot). It works. There's spots next to the nose for sinuses.
   Those are functional at least for me. The others? I don't know.
   But considering the fibrous network in the body, it wouldn't
   surprise me in the least. I had "theraputic touch" training back
   in the early 1990s at some 13 week weekend seminar thing, which
   seems related to this as well. It works too. Why it works? Don't
   know. Don't care. Sometimes "brush off negativity" from my
   shoulder to my hands. What's REALLY happening? Don't know, don't
   care. Painless, free, quick and it works. That's my attitude
   about these things. Use what works. I try not to get TOO into
   it, but I like things that are effective.
