ParkourMania
There are fewer predefined movements in parkour than gymnastics, as it does not have a list of appropriate "moves". Each obstacle a traceur faces presents a unique challenge on how they can overcome it effectively, which depends on their body type, speed and angle of approach, the physical make-up of the obstacle, etc. Parkour is about training the bodymind to react to those obstacles appropriately with a technique that works. Often that technique cannot and need not be classified and given a name. In many cases effective parkour techniques depend on fast redistribution of body weight and the use of momentum to perform seemingly impossible or difficult body maneuvers at speed. Absorption and redistribution of energy is also an important factor, such as body rolls when landing which reduce impact forces on the legs and spine, allowing a traceur to jump from greater heights than those often considered sensible in other forms of acrobatics and gymnastics.
According to David Belle, you want to move in such a way that will help you gain the most ground as if escaping or chasing something. Also, wherever you go, you must be able to get back, if you go from A to B, you need to be able to get back from B to A, but not necessarily with the same movements or passements.
Despite this, there are many basic techniques that are emphasized to beginners for their versatility and effectiveness. Most important are good jumping and landing techniques. The roll, used to limit impact after a drop and to carry one's momentum onward, is often stressed as the most important technique to learn. Many traceurs develop joint problems from too many large drops and rolling incorrectly. Parkour has sometimes received concerns for its health issues due to large drops. Communities in Great Britain have been warned by law enforcement or fire and rescue of the risk in jumping in the high buildings. Although David Belle has never been seriously injured while practicing parkour, there is no careful study about the health issues of large drops and traceurs stress gradual progression to avoid any problems. Despite this, the American traceur Mark Toorock and Lanier Johnson, executive director of the American Sports Medicine Institute say that injuries are rare because parkour is based on the control of movements not on what cannot be controlled.

Bad day in office
Stress is a prevalent and costly problem in today's workplace. About one-third of workers report high levels of stress. One-fourth of employees view their jobs as the number one stressor in their lives. Three-fourths of employees believe the worker has more on-the-job stress than a generation ago. Evidence also suggests that stress is the major cause of turnover in organizations.
Workplace stress is the harmful physical and emotional response that occurs when there is a poor match between job demands and the capabilities, resources, or needs of the worker. Stress-related disorders encompass a broad array of conditions, including psychological disorders and other types of emotional strain, maladaptive behaviors, and cognitive impairment. In turn, these conditions may lead to poor work performance or even injury. Job stress is also associated with various biological reactions that may lead ultimately to compromised health, such as cardiovascular disease.
Job stress results from the interaction of the worker and the conditions of work. Views differ on the importance of worker characteristics versus working conditions as the primary cause of job stress. The differing viewpoints suggest different ways to prevent stress at work. According to one school of thought, differences in individual characteristics such as personality and coping skills are most important in predicting whether certain job conditions will result in stress-in other words, what is stressful for one person may not be a problem for someone else. This viewpoint leads to prevention strategies that focus on workers and ways to help them cope with demanding job conditions. Although the importance of individual differences cannot be ignored, scientific evidence suggests that certain working conditions are stressful to most people. Such evidence argues for a greater emphasis on working conditions as the key source of job stress, and for job redesign as a primary prevention strategy.

Extreme Parkour - new movie
Parkour is a physical activity that is difficult to categorize. Often miscategorized as a sport or an extreme sport, parkour has no set of rules, team work, formal hierarchy, or competitiveness. On the contrary it is more like an art or discipline that resembles self-defense in the ancient martial arts. According to David Belle, "the physical aspect of parkour is getting over all the obstacles in your path as you would in an emergency. You want to move in such a way, with any movement, as to help you gain the most ground on someone or something, whether escaping from it or chasing toward it." Thus, when faced with a hostile confrontation with a person, one will be able to speak, fight, or flee. As martial arts are a form of training for the fight, parkour is a form of training for the flight. Because of its unique nature, it is often said that parkour is in its own category: "parkour is parkour."
An important characteristic of parkour is efficiency. Practitioners move not only as fast as they can, but also in the most direct and efficient way possible, this characteristic distinguishes it from the similar practice of free running, which places more emphasis on freedom of movements, such as acrobatics. Efficiency also involves avoiding injuries, short and long-term, part of why parkour's unofficial motto is etre et durer (to be and to last).
Those who are skilled at this activity normally have an extremely keen spatial awareness.
Traceurs claim that parkour also influences one's thought process by enhancing self-confidence and critical-thinking skills that allow one to overcome everyday physical and mental obstacles. A study by Neuropsychiatrie de l'Enfance et de l'Adolescence in France reflects that traceurs seek for more sensation and leadership than gymnastic practitioners. They also have a more narcissistic personality, but one that does not seem to be linked to maladaptive or psychopathologic behaviors.
