    Does the finger poke test have real value as a quick way to determine whether or not a person has good circulation/good blood flow in capillaries? By this I mean, a doctor once pressed his finger into my forearm with fairly good pressure... when he removed his finger the color immediately came back. He explained that I had good capillary circulation and the test was inclusive of my entire body, organs and all. He went on to say that if a "white" spot had lingered when he removed his finger it would indicate poor circulation. I wonder if anyone reading this post has ever heard of this before?

      I think the article is referring to the hormone level in the blood serum from specifically the endothelial cell that causes dialation of the capillar blood vessel that result in better perfusion in specific organs like the heart or the kidney. So the more capillary the better the perfusion in organs and an increase capillary means lower level of that hormone ADM. This might be a good bio-marker to track for longevity. Very complicated science article.
