The first time it happened it came as a shock to me just how bright red blood can be and just how fast it can bleed from a cut on the head. The color is startlingly different from the color I am used to seeing on cuts on hands and legs. I had read about the fact that arterial / oxygenated blood is brighter, but I never expected it to be that bright. I am very susceptible to vaso-vagal syncopes at the sight of blood so the second surprise was that I did not black out seeing it on my nephew. Maybe adrenaline changes that dynamics. Back to the article, it seems to me it seems that the author strongly wants to believe in a particular hypothesis and trying hard to make a case for it. Not very convinced.
