What it is saying though that we need to perhaps first ask whether exercise is,or lack there of is the underlying reason for the experience.Now why should not we do away if the results are very similar between exercise and medication?Why shouldn't we do away with medication? Here is why.You see, let's say…Let me just draw this circle.No. Let's say this is the total population of people who are depressed.We know that Zoloft, or antidepressant medication helps about 60 percent of them.And we know that exercise also helps 60 percent. However, it is not the same 60 percent.There is overlap by definition, because it is more than 50 percent.But it doesn't help the same people. So there are people who are only helped by medication;there are people who are only helped by exercise; and there are people who are helped by both.So it's not saying let's do away with medication. It is important. It helps.However it also says "let's try exercise, because I may be helped by exercise and not medication, or I may be helped by both.Here is the clincher though in the study: so what we are looking for, as I look in all these studies,is the relapse rates, meaning 6 months after the end of the study when we no longer give medication,when we no longer push the participants to exercise three times a week at least, what happens after 6 months?
