input: Dr. Havelock Ellis' 1933 book, Psychology of Sex, is one of the many manifestations of his interest in human sexuality. In this book, he goes into vivid detail of how children can experience sexuality differently in terms of time and intensity. He mentions that it was previously believed that, in childhood, humans had no sex impulse at all. "If it is possible to maintain that the sex impulse has no normal existence in early life, then every manifestation of it at that period must be 'perverse,'" he adds. He continues by stating that, even in the early development and lower function levels of the genitalia, there is a wide range of variation in terms of sexual stimulation. He claims that the ability of some infants producing genital reactions, seen as "reflex signs of irritation" are typically not vividly remembered. Since the details of these manifestations are not remembered, there is no possible way to determine them as pleasurable. However, Ellis claims that many people of both sexes can recall having agreeable sensations with the genitalia as a child. "They are not (as is sometimes imagined) repressed." They are, however, not usually mentioned to adults. Ellis argues that they typically stand out and are remembered for the sole contrast of the intense encounter to any other ordinary experience.  Ellis claims that sexual self-excitement is known to happen at an early age. He references authors like Marc, Fonssagrives, and Perez in France who published their findings in the nineteenth century. These early ages are not strictly limited to ages close to puberty as can be seen in their findings. These authors provide cases for children of both sexes who have masturbated from the age of three or four. Ellis references Robie's findings that boys' first sex feelings appear between the ages of five and fourteen. For girls, this age ranges from eight to nineteen. For both sexes, these first sexual experiences arise more frequently during the later years as opposed to the earlier years. Ellis then references Hamilton's studies that found twenty percent of males and fourteen percent of females have pleasurable experiences with their sex organs before the age of six. This is only supplemented by Ellis' reference to Katharine Davis' studies, which found that twenty to twenty-nine percent of boys and forty-nine to fifty-one percent were masturbating by the age of eleven. However, in the next three years after, boys' percentages exceeded that of girls.  Dr. Ellis also contributed to the idea of varying levels of sexual excitation. He asserts it is a mistake to assume all children experience are able to experience genital arousal or pleasurable erotic sensations. He proposes cases where an innocent child is led to believe that stimulation of the genitalia will result in a pleasurable erection. Some of these children may fail and not be able to experience this either pleasure or an erection until puberty. Ellis concludes, then, that children are capable of a "wide range of genital and sexual aptitude." Ellis even considers ancestry as contributions to different sexual excitation levels, stating that children of "more unsound heredity" and/or hypersexual parents are "more precociously excitable."

output: Katharine Davis' studies, which found that twenty to twenty-nine percent of boys and forty-nine to fifty-one percent were masturbating by the age of eleven.

input: Sullenberger was appointed to the United States Air Force Academy, entering with the Class of 1973 in June 1969. He was selected along with around a dozen other freshmen for a cadet glider program, and by the end of that year, he was an instructor pilot. In the year of his graduation, 1973, he received the Outstanding Cadet in Airmanship award, as the class "top flyer". Following graduation with a Bachelor of Science and his commissioning as an officer, the Air Force immediately sent Sullenberger to Purdue University to pursue a master's degree prior to entering Undergraduate Pilot Training (UPT).  Following completion of his graduate degree at Purdue, he was assigned to UPT at Columbus AFB, Mississippi, flying the T-37 Tweet and T-38 Talon. After earning his wings in 1975 as a USAF Pilot, he completed replacement training in the F-4 Phantom II at Luke AFB, Arizona. This was followed by his assignment to the 493d Tactical Fighter Squadron of 48th Tactical Fighter Wing at RAF Lakenheath, United Kingdom, where he flew as a United States Air Force fighter pilot in the F-4D Phantom II.  Following his assignment at RAF Lakenheath, he was reassigned to the 428th Tactical Fighter Squadron of the 474th Tactical Fighter Wing at Nellis AFB, Nevada, again flying the F-4D. He advanced to become a flight leader and a training officer, and attained the rank of captain, with experience in Europe, the Pacific, and at Nellis Air Force Base, as well as operating as Blue Force Mission Commander in Red Flag Exercises. While in the Air Force, he was a member of an aircraft accident investigation board.

input: Heffernan returned to Australia and began working for World Championship Wrestling (the Australian version, not the North American wrestling federation) under booker Jim Barnett as a singles wrestler. Costello was originally supposed to return to Australia as well and work for WCW, but those plans never came through. Instead, Costello remained in the United States and kept working in the tag team division, never seeking a career as a singles wrestler. Costello began wrestling for Georgia Championship Wrestling, where he teamed up with Louis Tillet to form a tag team known as "The Globetrotters"; a name that played off Costello's Australian and Tillet's French heritage. The Globetrotters defeated the Mysterious Medics in the finals of the Georgia NWA World Tag Team Championship but only held the titles for a week before losing them to Kurt and Karl Von Brauner on 4 February 1966. After this, the Globetrotters broke up due to differences in their approach to tag teaming.  Costello then moved to the NWA Mid-America territory near Nashville, Tennessee. In Mid-American, Costello teamed with Herb Welch to win the Mid-American version of the NWA World Tag Team Championship, which they held for just over 2 months. While still working in Mid-America, Costello began to team with Karl Von Brauner, who used a "German Nazi" gimmick despite being American. Under the management of "Playboy" Gary Hart, Costello and Von Brauner were billed as "The Internationals"; the team was later managed by George "Crybaby" Cannon. The Internationals worked mainly in Tennessee and Texas for NWA Western States. In Texas, Costello and Von Brauner won the Texas version of the NWA World Tag Team Championship, a title Costello and Heffernan had held in 1958. The team was also billed as the first NWA American Tag Team Champions, titles that were also recognized by World Class Championship Wrestling in addition to the Western States promotion. The Internationals lost the American Tag Team title to Fritz and Waldo Von Erich on 21 February 1967. Kurt then decided to go back to teaming with his storyline brother, Karl Von Brauner.  After the Internationals broke up, Costello returned to Australia to visit friends and relatives and to recuperate after many years on the road. On his way back to the United States, Costello had a stop over in Detroit, Michigan, where he met Cleo Williams. The two fell in love and married shortly afterwards, remaining together for the rest of Costello's life.
