Sometimes, there's no telling what you'll find when you crack open an egg. It's everyone's general hope that nothing unusual will come out of it, but one thing that's often ignored when inspecting the contents of that freshly cracked egg is the color of the yolk. Sure, it's supposed to be yellowish, but are we paying enough attention to just how yellow our egg yolks are? Findings indicate this detail may reveal more than you think.
