A new study collected data that shows that people who snore are more likely to gain weight than are people who do not snore. It is well known that many people who snore also stop breathing frequently during the night for a few seconds, a condition called sleep apnea. The interruption of breathing wakes the person-often so briefly that the waking goes unnoticed-and can leave the person too tired during the day to exercise. Anyone who snores, therefore, should try to eat less than the average person and to exercise more.

In this argument the speaker conclude that people who snores should try to eat less compared to the average person and to exercise more. To justify this conclusion, the speaker cites a statistic study about that people who snores are more likely to gain weight, and he also cites the evidence that may people who snores stop breathing frequently during the night, which can leave the person too tired during the day. Yet, close scrutiny of this supporting evidence reveals various logical problems, which render it unconvincing.

To  begin with, the survey the speaker cites is potentially problematic. We are not informed whether the survey’s respondent were representative of the overall population of the whole people who snores. Perhaps the sample only representative only a part of a region, or it only representative the old, for that matter, people’s behavior are various and it could not be a reliable evidence which was based on to draw a justifiably conclusion. The smaller the sample, the great possibility of biased results, and the less reliable the survey.

Moreover, even assuming the statistic that the argument cites are reliable, a direct correlation between the interruption of breathing wakes the person and the person feels too tired in day time does not necessarily prove that the former cause the later. It is entirely possible that other factors cause the person feels too tired. Perhaps the person often sleep very late, in other words, he or she cannot get enough sleep, in this way, even if people who do not snore, he or she still feels tired. Or perhaps the person was stressed by much pressure from work, and for a long time, he or she also would feel tired. Without accounting for other possible factors may contribute to the person’s tire, it is difficult to accept the conclusion that interruption of breathing during the night would cause the person feels tired.

Finally, even if the speaker substantiate all the forgoing assumptions, the speaker overlooks a myriad of other possible causes for that the person gain weight. It is equally possible that the person’s life is very well, with providing the enough good materials resources, gaining weight is easily achieved. Meanwhile, perhaps the person is natively easy to gain weight whatever he or she eats, for that matter, gaining weight have no business with the habit of snore. In short, without considering and ruling out other possible reasons, the speaker cannot justifiably conclude that people who snores are more likely to gain weight than people who not snores.

In sum, the argument is unpersuasive as it stands. The argument relies on a weak analogy and a series of unwarranted assumptions. To bolster the argument, the speaker should provide more information about the size and make up of the study’s sample, the real reason why these people who snores feels tired in their daytime. To better assess the argument, it would be useful to know the physical conditions of these people, and the real reasons why these people are more likely to gain weight.
