Context: Core stability refers to a person's ability to stabilize their core.  Stability, in this context, should be considered as an ability to control the position and movement of the core.  Thus, if a person has greater core stability, they have a greater level of control over the position and movement of this area of their body.  The body's core is frequently involved in aiding other movements of the body, such as the limbs, and it is considered that by improving core stability a person's ability to perform these other movements may also be improved i.e. core stability training may help improve someone's running ability.  The bodies core region is sometimes referred to as the torso or the trunk, although there are some differences in the muscles identified as constituting them.  The major muscles involved in core stability include the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm.  The minor muscles involved include the latissimus dorsi, gluteus maximus, and trapezius.  Notably, breathing, including the action of the diaphragm, can significantly influence the posture and movement of the core; this is especially apparent in regard to extreme ranges of inhalation and exhalation.  On this basis, how a person is breathing may influence their ability to control their core. Body language is a type of non-verbal communication in which physical behavior, as opposed to words, are used to express or convey information.  Such behavior includes facial expressions, body posture, gestures, eye movement, touch and the use of space.  Body language exists in both animals and humans, but this article focuses on interpretations of human body language.  It is also known as kinesics. Qigong, qi gong, chi kung, or chi gung () is a holistic system of coordinated body posture and movement, breathing, and meditation used for health, spirituality, and martial arts training.  With roots in Chinese medicine, philosophy, and martial arts, qigong is traditionally viewed as a practice to cultivate and balance qi (chi), translated as "life energy". Septima Poinsette Clark (May 3, 1898 – December 15, 1987) was an American educator and civil rights activist.  Clark developed the literacy and citizenship workshops that played an important role in the drive for voting rights and civil rights for African Americans in the Civil Rights Movement.  Septima Clark's work was commonly under appreciated by Southern male activists.  She became known as the "Queen mother" or "Grandmother" of the Civil Rights Movement in the United States.  Martin Luther King, Jr. commonly referred to Clark as "The Mother of the Movement".  Clark's argument for her position in the Civil Rights Movement was one that claimed "knowledge could empower marginalized groups in ways that formal legal equality couldn't." The history of qigong, the Chinese practice of aligning breath, movement, and awareness for exercise, healing, and martial arts training, extends back more than 4,000 years.  Contemporary qigong is a complex accretion of the ancient Chinese meditative practice xing qi (行氣) or "circulating qi" and the gymnastic breathing exercise tao yin (導引) or "guiding and pulling", with roots in the "I Ching" and occult arts; philosophical traditions of Confucianism, Taoism, and Buddhism, traditional Chinese medicine and martial arts; along with influences of contemporary concepts of health, science, meditation, and exercise. In humans, posture can provide a significant amount of important information through nonverbal communication.  Psychological studies have also demonstrated the effects of body posture on emotions.  This research can be traced back to Charles Darwin's studies of emotion and movement in humans and animals.  Currently, many studies have shown that certain patterns of body movements are indicative of specific emotions.  Researchers studied sign language and found that even non-sign language users can determine emotions from only hand movements.  Another example is the fact that anger is characterized by forward whole body movement.  The theories that guide research in this field are the self-validation or perception theory and the embodied emotion theory.

Jonathan Myrick Daniels (March 20, 1939 – August 20, 1965) was an Episcopal seminarian and civil rights activist.  In 1965 he was assassinated by a shotgun-wielding construction worker, Tom Coleman, who was a special county deputy, in Hayneville, Alabama while in the act of shielding 17-year-old Ruby Sales.  He saved the life of the young black civil rights activist.  They both were working in the Civil Rights Movement in Lowndes County to integrate public places and register black voters after passage of the Voting Rights Act that summer.  Daniels' death generated further support for the Civil Rights Movement.
