It is natural to assume that exercise would have a positive effect on the length of life for middle-aged men given all of the medical literature that has been published in the past showing a positive correlation between exercise and longevity.In this particular argument,the writer puts forth a study purporting to track five hundred middle-aged men with different occupations in different parts of the country.The survey was apparently conducted on the basis of an annual survey asking how often and how strenuously these men exercised.The writer not only concludes that there is a clear link between longevity and exercise,but that doctors should not recommend moderate exercise,rather vigorous outdoor exercise on a daily basis to all their patients.This writer's argument fails to convince in a number of areas due to several lapses in logical thinking.
