"In most societies, competition generally has more of a negative than a positive effect."


argument187

The following appeared as part of an article in a health magazine.
"A new discovery warrants a drastic change in the diets of people living in the United Sates.Two scientists have recently suggested that omega-3 fatty acids (found in fish and fish oils) play a key role in mental health. Our ancestors, who ate less saturated fat and more polyunsaturated fat, including omega-3 fatty acids, were much less likely to suffer depression than we are today. Moreover, modern societies-such as those in Japan and Taiwan-that consume large quantities of fish report depression rates lower than that in the United States. Given this link between omega-3 fatty acids and depression, it is important for all people in the United States to increase their consumption of fish in order to prevent depression."
