Comments from Google Buzz:

Luke Rosenberger - thanks! looks like original source of the life expectancy data (according to footnote) is actually a 2003 article from annals of internal medicine - http://www.ncbi.nlm.nih.gov/pubmed/12513041

Ves Dimov, M.D. - Looks correct. That's why I always say that we need a medical librarian on board... :)

For Google Buzz and Twitter, I typically link to the source where the text appeared when I first saw it. It's very nice to trace it back to the original source however. Thank you so much.

Luke Rosenberger - makes sense to me. you know us librarians, always reading the footnotes first ;-)
