The inauguration speech in January of 1937 was militantly humanitarian, and, to the President reveling in his electoral success, it seemed that only the Supreme Court stood in his path. He launched a strident attack on the institution within weeks of the beginning of his second term.
A yawn is a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath. Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality.
A long-standing hypothesis is that yawning is caused by an excess of carbon dioxide and lack of oxygen in the blood. The brain stem detects this and triggers the yawn reflex. The mouth stretches wide and the lungs inhale deeply, bringing oxygen into the lungs and hence to the bloodstream.s such, the stretching of jaw and face muscles seems to be necessary for a good yawn.The yawn reflex is often described as contagious: if one person yawns, this will cause another person to sympathetically yawn. The reasons for this are unclear; however, recent research suggests that yawning might be a herd instinct.
