DNA tests reveal core of illness and character

"Know thyself and you will know the universe," said the ancient Greeks. Well, one way to do that nowadays is via DNA analysis.

Just put 2 milliliters of saliva into a container, and send it to a DNA testing company. After 20 days, you will receive an online report detailing your ancestry, physical features, risk of disease, and physical and psychological traits.

While such testing was invented in the West, it is becoming increasingly popular in China.
