analyzing argument

 Katherine, S. (2011, April 20). Early retirement may be hazardous to your health. Los Angeles Times.
In this article Katherine intended to convince me of working longer is generally a good thing both intellectually and physically (par. 4). Her aregumant that continuing to work it good (par 4,5) is a claim of value which apeals to reason: she mentioned results of some studies that shows continuing working reduce the risk of cognitive skills. She has observed patients who quit thier job or continue to work for a long time. The result of patient's health are surely differntiated with to ways: it was good or bad. The credible results of research and studies are used in this article as logical evidences(overall paragraphs). The author completely convinced me through the article.
