Explanation:
Limitations of Correlations
Correlation is not and cannot be taken to imply causation. Even if there is a very strong association between two variables we cannot assume that one causes the other. For example suppose we found a positive correlation between watching violence on T.V. and violent behavior in adolescence.
An important limitation of correlational research designs is that they cannot be used to draw conclusions about the causal relationships among the measured variables. Consider, for instance, a researcher who has hypothesized that viewing violent behavior will cause increased aggressive play in children
-Affects most organs (liver, lungs etc.) in the body
-Increases the risk of death
-Increases the risk of getting a stroke, <span>coronary heart disease, lung cancer and other forms of cancer
-Can damage blood vessels
-Cause fertility issues</span>
