Is there a "Total Bitcoin Days" metric? Recently people have been talking about Bitcoin Days Destroyed. I am curious, is there a place I can find out something like Total Bitcoin Days: the number of days since each bitcoin has moved, all added together?

EDIT:

I am aware of Bitcoin Days Destroyed, and what they are (at least, I am pretty sure I am), I am looking for a metric that shows the opposite of Bitcoin Days Destroyed; maybe better wording would be "Bitcoin Days Not Destroyed". Perhaps my wording is off. Please suggest how I can clairify if so.
I think you are viewing the metric incorrectly. The notion of Bitcoin Days Destroyed is not relative to any other standard of measure. Rather, it is the standard of measure.

To clarify, there is no "gold standard" for Bitcoin Days Destroyed saying "if all Bitcoins had been spent within X weeks the total would be Y". That just doesn't make any sense. Think about it like this: how would one calculate what the DOW would be at today, had it not fallen 200 points? One wouldn't! It cannot be done; the points are there only to show the relationship of the market from day-to-day, month-to-month, or n-to-n. They have no standard to which they are measured.
