Frankly, Mr. Middle, I don't think the Author made that statement about Cookies and Milk - nor offered it as a possible remediation to Corvid-19. That statement was either made as a joke, or was made by someone he interviewed...before he wrote this piece. Frankly, I think he got that feedback from a child.
Kids are people too, ya know, and they have opinions ... and more significantly, kids sometimes have better ideas, and greater observation skills, and more understanding about things they encounter in life than a goodly number of us "highly educated", deeply experienced, "very intuitive" people - Ahmm.. that we think we are.
