Ever wonder why a Doctor will want to look at your hands.?
So much to be seen in the nails, vitamine deficiency, oxygen intake, dehydration, and toxic chemicals in the body.
The lines that go top to bottom, a small problem, if one has them going sideways then toxic tests are taken.
I believe anyone ill should stay away from any paint on hands or feet. Interesting, I read a paper that told of drinkers offten got this hammer look to their nails.
Frank has brought up an interesting subject. With all his cats he must notice the kneeding they do and sucking on whatever. Perhaps the nail biting is a replacement in humans to the loss of the teat or bottle. The Pacifier that most kids chomp on day and night, what use is it for.? Every where we go there are children as old as 3 with this thing stuck in their mouth.
Fun to think about all the out of the box Frank has set before us. BTW---why is that thing called a pacifier ,?
