Sheldon CooperSheldon Cooper was born in East Texas. A child prodigy, he went off to college at the age of eleven. After three years at the university he started his graduate studies, and earned his first Ph.D at the age of sixteen. He later added another Ph. D on top of his previous Ph. D and Master’s degrees. He claims his IQ is too great to be accurately measured, but it has been mentioned that it is probably around 187.
Sheldon is a strict creature of habit, relying entirely on things remaining the same. He has a spot on his couch, and refuses to sit anywhere else. He always eat the same food for each weekday, he moves his bowels at 8:00 am every morning, he has a set of pajamas for each day of the week, he always does his laundry on Saturday nights, he always visits the comic book store on Wednesdays, and Friday night is always vintage game night.
Initially he struggles greatly with irony and sarcasm, along with humor in general, but slowly begins to learn as the show progresses. Many agree that Sheldon suffers from high functioning autism or, more specifically, Asperger’s Syndrome.
Sheldon appears to be entirely asexual, and displays no interest what so ever in physical contact or intimacy. He does appear to be able to distinguish between various levels attractiveness, likely based on his knowledge of anthropology rather than any genuine sense of attraction.
Sheldon was initially intended to be the side character to the primary protagonist Leonard, but the fans immediately fell in love with Sheldon and he quickly became the show’s focal point, with Leonard, Penny and the rest serving as his aids in coping with relationships and social situations.
He is not prone to emotional talk, but has admitted that Leonard is his best friend, and that he also treasures his other comrades Penny, Howard and Rajesh. During season 4, Sheldon began an odd relationship with Amy Farrah Fowler who, he claims, is his “friend, and a girl, but not his girlfriend”.
