In the original version of this article one female non-centenarian was mistakenly included in the female centenarian cohort. This error alters the numbers presented in the Article slightly, but the conclusions are unaffected. As a result of the error, Table 1, Figure 2 and Figure 9 have been corrected, as well as some minor edits in the text. Both the HTML and PDF versions of the article have been corrected.
