question: Why, when we feel hot underneath the covers, does sticking one leg out cool us off, when obviously it is the body mass that is most uncomfortable?
comment: Because your foot shares the same blood supply as the rest of your body. When hot blood runs through your foot, and your foot now has access to cold air, it cools off while it is in your foot and then it gets pumped back to the rest of your body, cooling the rest of your body.
passages: Jeff wants the war to continue so that he will not have to go to classes, so he gives both teams an inspirational speech which keeps the war going. After Annie (Alison Brie) hears about this while treating injured players, she refuses to send text messages to Jeff or respond to his, and forcefully tells him to his face that Troy and Abed's friendship is at stake.
   Leg warmer
  
  Leg warmers are coverings for the lower legs, similar to socks but thicker and generally footless. Leg warmers are worn to keep the lower legs warm in colder weather. They can be tubular sleeves, long fabric wrappings, or simple pieces of fur or fabric tied around the calves. They are used in several outdoor activities and sports including cycling, soccer, hockey, hiking, ice skating, and dance.
   Section::::History.
  
  Bare legs have gone in and out of fashion many times in different cultures around the world. Examples of this fashion can be found as far back as 1066 with the Norman peasant class commonly baring their legs.
   Bare legs in England were a source of contention during the 1929 Wimbledon women's tennis tournament where a ban was considered and then ultimately rejected by English authorities, bare legs in women's tennis being the norm in both France and the United States at the time. Whilst western women's fashions through the first half of the 20th century and beyond gradually made the revealing of the leg acceptable or even the norm, the absence of any covering was often seen as having particular sexual connotations.
   Leg warmers can vary in length, and in width, due to the material's stretchiness. They are commonly worn between the ankle to just below the knee, though many dancers prefer it to extend to cover the lower parts of the thigh. Some cover the entire foot—these "warmers" usually have a pad that grips the floor so the dancer does not slip—however this has been known to cause career-ending injury. Some leg warmers are particularly short and made of thinner material; these are also known as "ankle warmers".
   For a bed bath, a bath blanket is put over the patient and only the area washed is exposed at a time for privacy and warmth. To make a mitt out of a washcloth, the fingers and palm of the dominant hand are placed over the washcloth and the washcloth is folded over the fingers and palm. The remaining part of the washcloth not covering the fingers and palms will be folded over and tucked in and the thumb will be out of the mitt.
   There is a function to determine the representative clothing insulation at each segment. One can also take into account the posture of the occupants. So far, all the clothing insulation value can be used when the occupant is standing. When occupant is sitting, one has to realize the insulation effect of the chair, and the decrease of insulation due to compression of the air in the clothing.
   The Anglican Canons of 1603 order that the Lord's Table should be "covered, in time of Divine Service, with a carpet of silk or other decent stuff, thought meet by the Ordinary of the place" (can. 82).
  
  Covers for lecterns and pulpits are generally similar to a frontlet, normally covering the "desk" of the lectern or pulpit and handing down about a foot or longer in front (visible from the congregation).

   Thigh weights are the most reasonable form of resistance. The location of the mass more readily duplicates the natural fat-storage mechanism of the human body and being closer to the core. In leg raise exercises, it allows more activation of the hip flexors (and abdominals) without putting more strain on the quadriceps muscles for extension, making it good for sports-specific training on movements like knees and jumping. The greater area and safe location allow it to handle much more weight. For those with wide thighs, such as bodybuilders with large quadriceps, or people with large amounts of fat stores on the inner thigh, it may cause chafing. If worn on both legs, however, the chafing would be between the weights and only damage them, possibly only chafing with a lack of tightness.
   Elephants have difficulty releasing heat through the skin because of their low surface-area-to-volume ratio, which is many times smaller than that of a human. They have even been observed lifting up their legs, presumably in an effort to expose their soles to the air.

   Originally worn by dancers to keep their muscles from cramping after stretching, in the early 1980s leg warmers became a fad and wearing them was fashionable among teenage girls; later to be an adopted fashion by boys in the city of Berkeley in the San Francisco Bay Area. Their popularity was partly due to the influence of the films "Fame" and "Flashdance" and the concurrent aerobics craze. They were worn with leggings, jeans, and tights or as part of aerobic wear. They were very popular in 1980's all over the world.
   Then ads alluding to leg hair removal began. While ads between 1920-1940 do refer to legs, legs were not the focus in 90% of those ads. The first ad in Harper's Bazaar that focused primarily on the legs appeared in 1929. The ad campaign against leg hair was not as voluminous as the campaign against underarm hair had been. However, writers for beauty magazines and books did reinforce the hairless-leg message. This had not happened in the Underarm Campaign.
   Among Western men, the shaving of legs is common in sporting situations and in fact has been taking place for longer than women shaving their legs. Male leg hair removal in modern times was initially related to sports, though it is now more frequently done for aesthetics. A recent study found that 9% of 45-60 year old American men and 5% of 30-45 year old American men trim or shave their legs, heavily contrasted by 40% of 25-30 year old American men.
   The popularity of pantyhose grew into a wardrobe staple throughout the 1970s and 1980s. From 1995 a steady decline in sales of pantyhose began, levelling off in 2006 with American sales less than half of what they had once been. This decline has been attributed to bare legs in fashion, changes in workplace dress code, and the increased popularity of trousers.
   Idiopathic leg cramps are common and typically affect the calf muscles at night. Edema also is common and in many cases idiopathic. In a small study of factory workers in good health, wearing compression garments helped to reduce edema and the pain associated with edema. A small study of runners found that wearing knee-high compression stockings while running significantly improved performance.
   In 1993, Stewart recorded a live version during his "MTV Unplugged" session which appeared on the album "Unplugged...and Seated". Artists who have recorded cover versions of "Hot Legs" include Tom Jones, Tina Turner, and American rock band Orgy. Bon Jovi have occasionally covered this song on the Circle Tour.
  
  Since the original recording/video, the lyrics in the last verse have been changed.
  
  The lead guitar that is prominent throughout the song was performed by Billy Peek, a Saint Louis, Missouri native who was in Rod Stewart’s band in the mid-seventies.
   A study by State University of New York researchers found that heat generated from laptops can increase the temperature of the lap of male users when balancing the computer on their lap, potentially putting sperm count at risk. The study, which included roughly two dozen men between the ages of 21 and 35, found that the sitting position required to balance a laptop can increase scrotum temperature by as much as . However, further research is needed to determine whether this directly affects male sterility. A later 2010 study of 29 males published in "Fertility and Sterility" found that men who kept their laptops on their laps experienced scrotal hyperthermia (overheating) in which their scrotal temperatures increased by up to . The resulting heat increase, which could not be offset by a laptop cushion, may increase male infertility.
   The pose is entered from kneeling by crossing the legs; the heel of the upper leg is tucked in under the lower thigh near the buttock. The arm on the lower leg side is raised, the forearm bent down, while the other arm reaches down behind the back, the forearm bent up, so the hands can clasp between the shoulder blades.
  
  The sitting position can be modified either by putting a folded blanket on the heels, and if need be also one beneath them.
   The cover is made with a single piece of vellum or alternative material, folded around the textblock, the front and back covers being folded double. The quires are sewn onto cords such as alum-tawed thongs and the sewing supports would be laced into the vellum cover. The thongs would also often be used at the fore edge of the covers to create a closure or tie.

   Such a garment is used by various persons in India "e.g." by women of various classes, by Sikh men, and most by Mohammedans of both sexes. It was adopted from the Mohammedans by Europeans as an article of "dishabille" and of night attire, and is synonymous with Long Drawers, Shulwaurs, and Mogul-Breeches [...] It is probable that we English took the habit like a good many others from the Portuguese. Thus Pyrard (c. 1610) says, in speaking of Goa Hospital: ""Ils ont force "calsons" sans quoy ne couchent iamais les Portugais des Indes"" [...] The word is now used in London shops. A friend furnishes the following reminiscence: "The late Mr. B—, tailor in Jermyn Street, some on 40 years ago, in reply to a question why pyjammas had feet sewn on to them (as was sometimes the case with those furnished by London outfitters) answered: "I believe, Sir, it is because of the White Ants."
   Hair removal product manufacturers initially focused their marketing on the upper class. Beginning in 1934, a similar type of advertising showed up in the middle-class Ladies' Home Journal that had been running in upper class Harper's Bazaar for the past 15 years.

  The 1920s extended the hairless ideal of the armpits to the legs as well. Hemlines rose on skirts and dresses from 1910-1927. Americans wore thick dark-colored stockings at first, which were taken over during this period by flesh-colored stockings to simulate the look of bare legs, without actually being bare.
   They are used as dancewear by ballet and other classic dancers in order to keep the leg muscles warm and to prevent cramping or other muscle injuries. No scientific data has been yet collected to substantiate the claim that leg warmers prevent injury.
  
  Traditionally knitted from pure sheep wool, modern variants are more typically made of cotton, synthetic fibers, or both. Some are made of other materials, such as chenille.
   Protection from the ground is an important aspect of emergency survival shelters. This is something that is not provided by a simple poncho shelter. A large percentage of body heat is lost to the ground. Sleeping directly on the ground without a layer of bedding can cause loss of heat. If the ground is wet, this can also pose a problem.

   On some vinyl pressings of the album, the cover does not crop off their feet. On the "Deluxe Edition" case the feet are presented on the back cover, and the band sold an official T-shirt with a shot of the band's feet after the deluxe edition release.
