Any further elaboration would raise the level of heat without any corresponding increase in light.
I often wonder why posts like this one ever show up at FR.
Probably because of statements such as this from the article:
The survey of 2,000 teenage girls across Britain with an average age of 14.5 years is the most comprehensive of its kind.
This makes it news, and this makes it relevant. Suggesting that "Any further elaboration would raise the level of heat without any corresponding increase in light" doesn't exactly give your fellow Freepers much credit for their ability to assess and comment upon news items in a meaningful way, does it?
If you think that it's irrelevant then you are entirely welcome to spend your time at a different thread, but insulting others who care about societal trends doesn't exactly add 'light' to the matter.
