Real cinnamon
LA Times on cinnamon (via Mental Floss): 
There are actually two spices known as cinnamon. Both come from the dried bark of evergreen trees of the Lauraceae (laurel) family. True or Ceylon cinnamon comes from Cinnamomum zeylanicum, a tree native to Sri Lanka and the southwestern coast of India along the Arabian Sea... The less expensive Chinese cinnamon, otherwise known as cassia, comes from the related tree C. aromaticum and is produced more widely. From China it is exported as Kwangsi, Yunnan and Honan cinnamon; from Laos, Cambodia and Vietnam as Saigon cinnamon; and from Indonesia as Korintje, Padang and Vera cinnamon. Most of the cinnamon imported by the United States is cassia.
Whoa.  "Brown sugar and cassia" doesn't evoke nearly the feeling of elation that comes with the phrase "brown sugar and cinnamon." #food

The Beanie Babies Bubble
Mental Floss has an interesting re-post about the Beanie Babies Bubble of the late 1990s.  I personally never participated in this elite investment opportunity, and I remember thinking at the time how ridiculous it was to believe a collection of stuffed animals would produce a good return for your money.  People are stupid. #lifestyle

ADHD and diet
A recent scientific study has shown that 64% of children diagnosed with ADHD are actually experiencing a reaction to certain foods they eat.  They can undergo a fairly simple though rigorous test to determine (a) if they've been misdiagnosed with ADHD, and (b) if so, what specific foods cause their hypersensitivity. #health
