Cold refers to the condition or subjective perception of having low temperature. A cold body is often described as the opposite of hot, or as having less heat, although the latter use of "heat" would be incorrect in the context of physics, as heat refers to the transfer of energy between bodies, which do not "have" heat themselves.

A lower bound to temperature is the absolute zero, defined as 0 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale, −459.67 °F on the Fahrenheit scale, and 0 °R on the Rankine scale.

Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in this classical sense. The object would be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because of the uncertainty principle.

Aaron Lewis, (born April 13, 1972), is the lead vocalist, rhythm guitarist, and founding member of the rock group Staind, with whom he has released seven studio albums. He has since ventured into country music with his debut solo album, Town Line. The EP was released on March 1, 2011 on Stroudavarious Records. Lewis' first full-length solo release, The Road, will be released by Blaster Records on August 14, 2012.

Lewis grew up, largely, in Longmeadow, Massachusetts, then moved to the Forest Park section of nearby Springfield from 8th grade through high school. His mother is Jewish with origins in Russia, Poland and Germany and his father is Catholic of Italian, Welsh and English origin. His hobbies include fishing, playing golf, riding his motorcycle and dirt bike, as well as hunting. He has worked in landscaping, cleaned hotel rooms, and played solo acoustic sets in bars, pool halls, restaurants and coffeehouses.

Lewis was, before Staind, in a band known as J-CAT with Tori Sands, Chris Ballini, and former Staind bandmate Jon Wysocki. An album surfaced on the internet with nine of J-CAT's performances at Club Infinity in Springfield, Massachusetts. The performances were recorded while Dysfunction was being recorded. Two of Staind's popular singles—"Outside" and "It's Been Awhile"—were both originally performed by J-CAT with somewhat different lyrics.

Steve Austin (born Steven James Anderson, later Steven James Williams; December 18, 1964), better known by his ring name "Stone Cold" Steve Austin, is an American film and television actor, producer, and retired professional wrestler. Austin wrestled for several well-known wrestling promotions such as World Championship Wrestling (WCW), Extreme Championship Wrestling (ECW) and most famously, the World Wrestling Federation (WWF). Described by WWE (formerly the WWF) chairman Vince McMahon as the most profitable wrestler in the company's history, he gained significant mainstream popularity in the WWF during the mid-to-late 1990s as "Stone Cold" Steve Austin, a disrespectful, beer-drinking antihero who routinely defied McMahon, his boss. This defiance was often shown by Austin flipping off McMahon and incapacitating him with the Stone Cold Stunner, his finishing move. McMahon inducted Austin into the WWE Hall of Fame in 2009.

Austin held twenty championships throughout his professional wrestling career, and is a six-time WWF Champion as well as the fifth Triple Crown Champion. He was also the winner of the 1996 King of the Ring tournament, as well as the 1997, 1998 and 2001 Royal Rumbles. He was forced to retire from in ring competition in early 2003 due to a series of knee and neck injuries sustained throughout his career. Throughout the rest of 2003 and 2004, he was featured as the Co-General Manager and "Sheriff" of Raw. Since 2005, he has continued to make occasional appearances. In 2011, Steve Austin returned to WWE to host the reality series Tough Enough.
