It is quite hard to define exactly what a physical disability is; it is very crucial to not make the mistake that it is only having to use a wheelchair of wear a brace. There are many conditions, which are considered a physical disability such as multiple sclerosis and chronic fatigue syndrome (Wen,1999). When talking about physical disability it is easy to categorize it into a number of things, some of which are talked about here, these include limited control or some or all voluntary muscles, meaning in the arm, which ranges from no control to normal coordination, in the legs which ranges from total inability to difficulty standing or walking. In the upper body which includes the inability or difficulty to sit straight, in the face and throat, which includes the difficulty, to eat and speak and finally the bladder and bowel which means having issues using the toilet. Other physical disabilities can include an underdeveloped skeletal structure and dysfunctional joints (Accardo, 1996). There are a number of causes as to why someone has a physical disability. Accidents which could result in spinal injury, amputation, acquired brain injury affecting moto

There is intensive, complicated research regarding various body chemical causes or contributors to obesity, such as those produced in the brain and other organs. We will know increasingly more about these in the near future.

While looking at disability broadly it seems that a number of conditions, which cause disability, are left out. On of the major causes of physical disability is obesity. So what causes obesity?

Obesity is a common condition, which can have profoundly negative health and social consequences. Obesity is considered a serious disease and has been linked to shortened life expectancy. Obesity is a condition, and morbid obesity is a disease, not a character flaw. The most important cause of obesity is a person's genetics. It is the one thing relative to obesity that a person can do nothing about. Another important cause is a person's lifestyle. That includes eating habits and exercise patterns. The third cause, although it is not nearly important as the other two, is a person's psyche. We all eat at times other than when we are hungry. Often, psychological pressures stimulate increased intake of food (Goodstein, 1983).

Because genetics play a very important part in the cause of obesity, a person who has genetic obesity should avoid feeling guilty. The genetics cause a biologic need for the obesity. The only way it can be avoided is by choosing a healthy lifestyle.(Goodstein, 1983). Adults who a
