Group nouns

We use many collective nouns in our thinking and communication.  We speak of the US or Earth or the stock market.  Our usage is much the same as when we are speaking of one person or one event.  "The weather has been cool here lately."  What weather?  All day and all night?  Every day or just MOST days?  We have to use "trends" and generalities and it is probably one of our most valuable abilities that we can.

BUT, sometimes it pays to take a moment to ask ourselves about the masses or collections we are thinking about.  Whenever we are thinking about something, it can be eye-opening to ask if there are component parts, sub-divisions, separate people or opinions or feelings or histories.  There almost always are.  Even A body might have important differences between the head and the feet or the right and the left eye.  

"This Green Bay Packers this…" and "Media are that…" but we can find Packers that aren't and media that aren't.
