There is a positive, a reasonable conclusion, if you did the study appropriately, would be that more computer time correlates with higher blood pressure, or that higher blood pressure correlates with more computer time. Now when you do these observational studies, or when you interpret these observational studies, when you read about someone else's, it's very important not to say, oh well, this shows me that computer time causes blood pressure. Because this is not showing causality. And you also can't say, maybe you might say somehow blood pressure causes more people to spend time in front of a computer. That seems even a little bit sillier, but they're actually the same. Because all you're saying is that there's a correlation, these two variables move together. You can't make a conclusion about causality, that computer time causes blood pressure, or that blood pressure causes some time, high blood pressure causes more computer time.
