This might be old news to many, but I had never heard of it.
The Hispanic Paradox: U.S. Hispanics Live Longer, Despite Socio-Economic Hurdles
Data on Hispanic Immigrants Presents Puzzle on Aging
This is very interesting to me, because we usually assume that socioeconomic variables like access to health care, level of education, and income almost fully determine one's life expectancy. But for a lot of Hispanics, that really isn't the case. A lot of them live long, happy lives and prove themselves to be resilient in the face of chronic diseases, despite scoring low on all these socioeconomic measures. This is even stranger because Latin Americans living in their native countries aren't very healthy on average.
Could it be that familialism and religiousness, major parts of Hispanic culture, are actually good for your health? If Latin American countries weren't so poor and dangerous (high crime and violence rates lowering life expectancy rates), would the positive effects of these cultural features really stand out?
