Long-Lived Hispanics!

Eugene Volokh at the Volokh Conspiracy blog pulls together a fascinating set of links and observations regarding an obscure but interesting (at least I never heard it--feel free to upbraid me for behind-the-times ignorance) demographic fact: that in America, "foreign-born Mexican and Other Hispanic adult[s]…experienc[e] mortality rates that are 35% to 47% lower than those experienced by non-Hispanic whites…these differences translate into approximately five to eight years of additional life expectancy at age 45." Apparently, there's no settled theory explaining this that's totally convincing--though these results may also be merely "due to data problems and differing methodologies." Following all the links and arguments in the post provides a demo-fabulous time for all.
