The power of... milk.

In the book 'Blink' (blink) by Malcolm Gladwell which I recently read it said that statistically  those who are CEOs are on average over 6 foot tall (for men), and in Vietnam this is reflected by the strong belief in the power of milk. There are these milk shops everywhere in town, TrueMilk is one of the biggest chains selling only one product, guess what it is!
