"Don't judge a book by its cover" has become a cliché, and yet the underlying truth has never been more true than in the present day. Deception, subterfuge, misdirection and camouflage are to be found throughout the natural world. In the human domain they are even more prevalent. Take for example the foods we eat. What is sold as "real" food is often a food-like substance, a laboratory concoction deceptively packaged and marketed. "Real food for Real People." -- Ad slogan for Nutrisystem, a company that sends pre-packaged diet foods to subscribers through the mail. (What Real Food looks like.) Contracts have fine print in legalese. People are often not whom they are trying to seem. And we may also not be who we think we are. Each of us has some content we conceal from ourselves. Depending on the context and the card position, consider this a propitious time to look beneath the surface of whatever you are contemplating and scan it for concealed content.
