Okay, wise guy, why is blood red?
———- from Cool Hand Uke of Sparks NV
Blood is actually chartreuse. However, since the mind could not handle seeing such a color leak from the body, our eyes tell us a little white lie and interpret the chartreuse as red. Our fingernails, for instance, are actually mauve, but a conspiracy by cosmetic firms have ensured that our eyes don’t dare tell the truth about nail color. In short, people, I’m telling you that our eyes are liars! Inveterate people pleasers, they bend the truth in a desperate attempt to win friends. Once the lie is uncovered, the eyes close and feign sleep. When eyes are irritated, they’re irritated with themselves for being such spineless wimps. Sorry if it’s all so complicated, but that’s how most of biology is: messy, smelly and complicated. Especially to the human eye.
