How to prevent osteoarthritis?
A sedentary lifestyle makes for weak muscles and increases the odds of developing arthritis (and other health problems). Regular exercise is essential. It creates stronger and more flexible joints. Exercise doesn't have to be strenuous. Just regular (yoga can really help). Feed your joints right. Overweight and obese individuals are at greater risk for osteoarthritis, particularly in the weight-bearing joints. Losing weight cuts the risk. Improving the diet is always a tough challenge in our time-strapped society. However, the more you can maximize your intake of whole foods and minimize the refined, packaged foods, the better off you and your joints will be.

What are the similarities between the left and right hemispheres?from en.wikipedia.org
Rather than just being a series of places where different brain modules occur, there are running similarities in the kind of function seen in each side, for instance how right-side impairment of drawing ability making patients draw the parts of the subject matter with wholly incoherent relationships, or where the kind of left-side damage seen in language impairment not damaging the patient's ability to catch the significance of intonation in speech. This has led British psychiatrist Iain McGilchrist to view the two hemispheres as having different value systems, where the left hemisphere tends to reduce complex matters such as ethics to rules and measures, and the right hemisphere is disposed to the holistic and metaphorical.
What is the cause of Wernicke's aphasia?from en.wikipedia.org
Wernicke's aphasia is the result of damage to the area of the brain that is commonly in the left hemisphere above the Sylvian fissure. Damage to this area causes primarily a deficit in language comprehension. While the ability to speak fluently with normal melodic intonation is spared, the language produced by a person with Wernicke's aphasia is riddled with semantic errors and may sound nonsensical to the listener. Wernicke's aphasia is characterized by phonemic paraphasias, neologism or jargon. Another characteristic of a person with Wernicke's aphasia is that they are unconcerned by the mistakes that they are making.
