Actually it is very expensive. I am talking about consuming a lot of grams every day, 50 to 100 grams, which is not a lot given it is roughly 1/1000 of the weight of a normal human, but it is the luxury of a millionaire for the moment. It is true that we most probably don't see any statistical correlation between saffron consumption and intelligence, especially in a country level, but i would argue, that the dosage makes the genius.

Some of the virtues of the article, are a state of mind anyway, that's why i mention saffron. Many people are eating too much, only to feel better. Food has certainly the ability to alter our state of mind, which in some cases ends up in obesity.

Virtues in the article, like apatheia, ataraxia, eudaimonia include in their meaning, not indulging in every pleasure in excess, and food is one of them. Well, that can be automated by producing more saffron and lowering it's price.
