Sleep is a naturally recurring state characterized by reduced or absent consciousness, relatively suspended sensory activity, and inactivity of nearly all voluntary muscles. It is distinguished from quiet wakefulness by a decreased ability to react to stimuli, and is more easily reversible than being in hibernation or a coma. Sleep is a heightened anabolic state, accentuating the growth and rejuvenation of the immune, nervous, skeletal and muscular systems. It is observed in all mammals, all birds, and many reptiles, amphibians, and fish.
The purposes and mechanisms of sleep are only partially clear and are the subject of intense research. Sleep is often thought to help conserve energy, but decreases metabolism only about 5–10%. Hibernating animals need to sleep despite the hypometabolism seen in hibernation, and must return from hypothermia to euthermia in order to sleep, making sleeping "energetically expensive."
In mammals and birds, sleep is divided into two broad types: rapid eye movement (REM) and non-rapid eye movement (NREM or non-REM) sleep. Each type has a distinct set of associated physiological, neurological, and psychological features. The American Academy of Sleep Medicine (AASM) further divides NREM into three stages: N1, N2, and N3, the last of which is also called delta sleep or slow-wave sleep (SWS).
Willard Mitt Romney (born March 12, 1947) is an American businessman and the presumptive nominee of the Republican Party for President of the United States in the 2012 election. He was the 70th Governor of Massachusetts (2003–07).
The son of Lenore and George W. Romney (Governor of Michigan, 1963–69), he was raised in Bloomfield Hills, Michigan. In 1966, after one year at Stanford University, he left the United States to spend thirty months in France as a Mormon missionary. In 1969, he married Ann Davies, and the couple had five children together. In 1971, he earned a Bachelor of Arts degree in English from Brigham Young University and, in 1975, a joint Juris Doctor and Master of Business Administration from Harvard University as a Baker Scholar. He entered the management consulting industry, which in 1977, led to a position at Bain & Company. Later serving as Chief Executive Officer, he helped bring the company out of financial crisis. In 1984, he co-founded the spin-off Bain Capital, a private equity investment firm that became highly profitable and one of the largest such firms in the nation. His net worth is estimated at $190–250 million, wealth that has helped fund his political campaigns. Active in The Church of Jesus Christ of Latter-day Saints, he served as Ward Bishop and later Stake President in his area near Boston. He ran as the Republican candidate in the 1994 U.S. Senate election in Massachusetts, losing to long-time incumbent Ted Kennedy. In 1999, he was hired as President and CEO of the Salt Lake Organizing Committee for the 2002 Winter Olympics and Paralympics; and he helped turn the fiscally troubled games into a success.
