Example of what I'm thinking of; I walked into a friend's work one day took one look, and KNEW she was SICK, and chose to be gentle - her face was WHITE, her pupils constricted. She had a BAD headache, we could tell at a glance. I ended up giving her some Acetaminophen I had on me, so she didn't have to go buy some.We have the phrases "You look like death warmed over!", "You look down", "You look like you're not feeling very good."? I'm wondering if a visual scan of the skin - one rather important organ of the human body - (perhaps just face & hands, perhaps even full-body) would help identify & quantify some health problems, emotional states, ???, when compared against a baseline history. If you come in & your skin's blotchy looking & pale & you hurt but your doctor doesn't notice as he/she's too busy, and your condition doesn't get treated, it's not good. They're using dogs to sniff out cancer cells, why not a very accurate camera?
I've seen some people I know darn near totally ignore their bodies & get to where they cannot (for example) close a car door anymore with one arm (weird, long story.) Some doctors are as bad, or worse.
My cats taught me how to 'see' sore muscles. They come stand on 'em, one or two paws per sore spot. I've taken a little bit of training on many kinds of massage, Rolfing, Acupressure, electrostimulation, craniosacral work, etc., trying to figure some things out for Robin in the past; My question on all this is, I wonder if we can sense & figure out what the human brain does to do these kinds of things? Our eyes do a lot of it, I figure (From an experiment I ran once with videotape, sans audio, and with photos another time, asked a few people to tell me their impressions about each person's muscle pain who was on the clip. Fascinating amount of data (with decent accuracy) from our eyes! Our eyes process almost as much sensory info as a dogs' nose does.)
