Why when we have no choice at all do we say it’s a “Hobson’s choice”?
Thomas Hobson lived between 1544 and 1631 and was the owner of a livery stable in Cambridge, England. He was a very stubborn man Whom Seinfeld might have called the “Livery Nazi” because, regardless of a customer’s rank, he would rent out only the horse nearest the stable door. Hobson became famous for never renting horses out of order, so “Hobson’s choice” came to mean, “take it or leave it.”

Benefits of Apples
Apple polyphenols are standout nutrients in this widely loved fruit. These polyphenols include flavonols (especially quercetin, but also kaempferol and myricetin), catechins (especially epicatechin), anthocyanins (if the apples are redskinned), chlorogenic acid, phloridizin, and several dozen more healthsupportive polyphenol nutrients. Apple is a good source of fiber, including the soluble fiber pectin, and its also a good source of vitamin C. Apple nutrients are disproportionately present in the skin, which is a particularly valuable part of the fruit with respect to its nutrient content.
