Input: Read this: Emotions are complex. According to some theories, they are a state of feeling that results in physical and psychological changes that influence our behavior. The physiology of emotion is closely linked to arousal of the nervous system with various states and strengths of arousal relating, apparently, to particular emotions. Emotion is also linked to behavioral tendency. Extroverted people are more likely to be social and express their emotions, while introverted people are more likely to be more socially withdrawn and conceal their emotions. Emotion is often the driving force behind motivation, positive or negative. Definition has been described as is a "positive or negative experience that is associated with a particular pattern of physiological activity." According to other theories, emotions are not causal forces but simply syndromes of components, which might include motivation, feeling, behavior, and physiological changes, but no one of these components is the emotion. Nor is the emotion an entity that causes these components

The Tulsa Talons moved to San Antonio, Texas and Jeffrey Vinik became owner of the Tampa Bay Storm. The Dallas Vigilantes were left off the schedule for the 2012 season with no announcement from the management, raising speculations that either the team had suspended operations for the season or was ceasing operations altogether. (Apparently the latter was the case as the organization did not field a team for the 2013 season or any subsequent one either.) Like the National Football League, the AFL postponed the free agency period to October 31 due to Hurricane Sandy.

The flag of the Communist Party of China became a red banner with a hammer and sickle, similar to that on the Soviet flag. In the 1950s and 1960s, other Communist regimes such as Vietnam and Laos also adopted red flags.
