We often take our hands for granted. We use them all of the time. There are 27 bones in our hands. Half of those are located in our fingers. Each finger has three bones and the thumb has only two. Scientists have estimated that our fingers will bend and flex 25 million times over the course of our lifetime! Our fingers have amazing nerve endings and touch receptors capable of sensing temperature, texture, pressure, movement, and much more. The human body has more than 600 muscles helping it to move, walk, and run. Interestingly, our fingers have none—zero! So how do fingers perform the intricate tasks, with so much dexterity, without any muscles? 

The United States is the only country in the world that requires the washing of eggs before they are sold. As a result, the outside membrane called the cuticle is washed away, leaving them vulnerable to outside bacteria and other sources of spoilage. That is why they must be refrigerated. You can feel the cuticle on a freshly-laid egg as little bumps on the surface of the shell.

​Once refrigerated, they cannot sit on the counter. The U.S. Department of Agriculture (USDA) explains: “After eggs are refrigerated, they need to stay that way. A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg and increasing the growth of bacteria. Refrigerated eggs should not be left out more than 2 hours.”
