A few pieces of supplemental info:
1) An editorial
in the British Medical Journal written by Pickett & Wilkinson. This gives an overview for the research and results relating equality and health. Note that there is a link to the meta-analysis Pickett refers to in the video at the bottom of the article. Definitely worth a look.
2) The slides
used in the video in case anyone wanted a closer look.
Also, epidemiologists rock! Of course...I may be biased on that point given my career aspirations...
[EDITORS NOTE: The post ends here suddenly with no explanation. The findings of our institute hypothesize that the evidence is consistent with the author being spirited off to Sweden.]
