Can anyone verify the origin/publication for this quote?

"Life is not measured by the number of breaths we take, but by the moments that take our breath away."

http://www.goodreads.com/quotes/show/...

Disputed sources online list the following:
- Hilary Cooper
- Maya Angelou
- George Carlin
- a Carleton greeting card in the 1970′s.

Google Books shows no sources prior to about 2005, and the most common attribution is "Unknown" so I have added it to Anonymous with a misattributed tag. (The alleged Carlin quote that included that text—actually from a spam forwarded email—should not have included it; the rest I have corrected and linked to the real author, Bob Moorehead)

In case this helps, Quote Investigator has investigated this and concludes: "In conclusion, this entry represents a snapshot of salient pieces of evidence QI has located. Currently, Vicki Corona is the leading contender for originator, but she laudably admitted to some uncertainty." Full post:

Thanks for that update, Carlo.

It seems that the original quote link that I updated to Bob Moorehead above was deleted in the intervening nine years, but one now exists for Corona:

I have tagged a few others that make use of the quote embedded in quotes of their own:

I am in the process of correcting and merging several other misattributions, including three different variations for Maya Angelou, along with Ajay K. Pandey and Jillian Dodd.
