Even if the saying "cold hands, warm heart" were really true, the warmhearted probably would prefer to give up frozen fingers during the winter. In Japan, where central heating is still something a luxury, Aoi Co., Ltd. has been distributing a small, disposable hand-and-body warmer that makes use of a harmless chemical reaction in order to generate heat. This winter the Poco body warmer is making its debut in Canada, the United States and parts of Europe. In addition to chasing away winter chills, the body warmer can be used to help relieve pain that results from muscle sprains and arthritis. The Poco body warmer measures about three by five inches and is one-quarter inch thick. It consists of a cloth bag containing a mixture of iron powder, moisturized wood powder, activated carbon and salt. To get it going, the user simply opens the outer vinyl bag in which the unit is vacuum-packed and shakes the cloth bag. The unit then absorbs oxygen from the air, which in conjunction with the moisture from the wood powder oxidizes the iron, giving off heat. The packet maintains an average temperature of 140 degrees Fahrenheit for 24 hours, according to the manufacturer. Aoi Co. officials say that the product contains no toxic chemicals.

HINCKLEY, John W., Jr. (1955-): Accused Assailant of Ronald Reagan On March 30, 1981 Ronald Reagan became the eighth sitting president of the United States to be subjected to an assassination attempt and the fourth —— after Andrew Jackson, Harry Truman and Gerald Ford —— to survive. Reagan was shot by a 25-year-old drifter, John W. Hinckley of Evergreen, Colo., as he left the Washington Hilton Hotel, where he had addressed a labor audience. The assailant was seized immediately after having fired four to six shots from a 22-caliber revolver, a type entered under the left armpit, pierced the chest, bounced off the seventh rib and plowed into the left lower lobe of the lung. Reagan froze for a moment at the door of his limousine and then was brusquely pushed inside the car by a Secret Service agent. Remarkably, the President did not realize he had been shot but thought he had simply been injured when shoved into the car. Only upon arrival at the hospital was it determined that he had been shot. Also wounded were three others: the Presidents press secretary, James S. Brady; a Secret Service agent, Timothy J. McCarthy; and a District of Columbia police officer in Dallas and moved with his family to Colorado in 1974. He had attended Texas Tech University but never graduated. At times he had traveled across the country, and in 1978 he had enrolled himself in the National Socialist Party of America, generally known as the Nazi Party of America. A spokesman for that organization said the group had not renewed Hinckleys membership the following year because of his "violent nature".
