Your original statement states a cause, alludes to an effect, but doesn't really explain why you believe the statement to be true. I was curious to hear your explanation of why you think your statement is valid.
Excuse me, but your prior post explained nothing. You took two concepts/facts and stated that there was a correlation between the two. But you provided no evidence of such correlation, and yes, I know what a correlation is. I also know what causation is. The existence of two separate circumstances or lifestyle indicators does NOT prove a correlation. Or that one causes another. You've simply spouted your theory, which you are entitled to do, but absent more than your opinion, it is ONLY your end thought.
You are both mistaken about your guesses about what the word "correlation" means.
Again, I refer you to the difference between correlation and causation.
One of the most common errors we find in the press is the confusion between correlation and causation in scientific and health-related studies. In theory, these are easy to distinguish — an action or occurrence can cause another (such as smoking causes lung cancer), or it can correlate with another (such as smoking is correlated with alcoholism). If one action causes another, then they are most certainly correlated. But just because two things occur together does not mean that one caused the other, even if it seems to make sense.

The info regarding the trend in teenage sexual behavior was provided earlier. The info regarding the trend in obesity is widely available.

Try not to get so defensive with such a condescending attitude when people ask for clarification. Stop being shy and just address why you brought the "study" you referenced into the conversation.
But then, this is your modus operandi, isn't it? Have a pleasant evening. You are almost always amusing, although you rarely INTEND to be.
