In the memo the editor shows that according to a study in nearby East Meria, where fish comsumption is very high, people seldom go to see doctor for dolds.Thus the editor falsely concludes that eating a substantial amout of fish can prevent colds.And he suggests people to use Ichthaid, a nutritional supplement derived from fish oil, everyday because he considers it to be a good way to prevent colds and lower absenteeism. However, I cannot accept this incorrect conclusion as it stands.
First of all, the casual link between the large amount of fish eating and colds preventing in East Meria is too weak. There are also many alternatives to explain it, such as besides eating a lot of fish, people there also eat enough some special food including materials against colds. Or the physical fitness of these people are good inborn and they seldom had colds before they began to eat a lot of fish. Without rulling out these possible explanation the editor cannot convince me that the seldom colds getting results from the substantial amount of fish eating.
Secondly, even if the function of the fish eating is obvious and reduce the colds in East Meria in deed. We cannot see that people here will benefit from eating fish too. Maybe we have totally different gene or physical fitness from people in East Meria. Even more we are perhaps allergic to any kind of fish, let alone to prevent colds from eating a lot of fish. Consequently, the editor cannot arbitrarily conclude that we could take the Ichthaid.
Thirdly, the editor falsely concludes that colds are the reason most frequently given for absences from school and work, thus to reduce the absenteeism in shool and work we should eat the recommended Ichthaid as to prevent colds. However, this inferrence is so firm as colds are actually not the main reason for the absenteeism. In respect that when people are absent from school and work, they are always reluctant themselves for various of subjective reasons instead of objective reasons. Therefore the reduce of colds cannot benefit the attendance if the students and workers don't have a good sense. In this way daily use of Ichthaid cannot lower absenteeism as the editor points out.
To sum up, the conclusion in this memo is not well reasoned and we cannot take any advantage from Ichthaid in this memo.
