Test the "Coolidge results" in humans.
President Calvin Coolidge (1872-1933) is a glum, noiseless guy, so this trait generated him the nickname “Silent Cal.” Their emotionless countenance would be so popular that if their loss was established, the satirist Dorothy Parker quipped: “How can they determine?”
But underneath that cool attitude raged a voracious sex-related cravings. One-day the Coolidges were traveling a chicken farm any time Mrs. Coolidge noticed that the rooster is mating usually on your hens. “How often times just one day really does this individual match?” she questioned the manual. “Dozens,” the guy replied. “Tell that to Mr. Coolidge,” she insisted.
On hearing in this swap, Mr. Coolidge asked, “Each moments with similar hen or a different one?” The manual informed him or her it actually was usually with another type of hen.
