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.
In humans, yawning can start as early as 20 weeks after conception. A yawn is a coordinated movement of the thoracic muscles in the chest, diaphragm, larynx in the throat, and palate in the mouth. By yawning, we help distribute surfactant (wetting agent) to coat the alveoli (tiny air sacs) in the lungs. Generally speaking, we cannot yawn on command.
