I found one error in your article: “This just in: It’s OK to be fat, Canadian university study says”.
Within the article was this outdated observation: “Some 18-year-old thin-as-a-rail Ticas are ready to try out as a sumo wrestler by the time they are 35 and after four kids.”
This would be more realistic to the current day obesity epidemic sweeping Costa Rica: Some 18-year-old Ticas are ready to try out as a sumo wrestler already, where as it used to take 35 years and four kids to qualify. Times (and obesity rates) are changing in Costa Rica within one generation.
Get out and take a look.
