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.
As for the etiology of yawning, for many years it was thought that yawns served to bring in more air because low oxygen levels were sensed in the lungs. We now know, however, that the lungs do not necessarily sense oxygen levels. Moreover, fetuses yawn in utero even though their lungs arenÂ¿t yet ventilated.
