The Agence France Presse today reports that a Japanese dairy company on Thursday announced the launch of super-premium milk for stressed-out adults — at the price of $43 for a 900 mL, or 1 qt bottle.

According to the story, Tokyo-based Nakazawa Foods will launch the "Adult Milk" line of products in October targeting "adults who live in a stressful society."

The price of 5,000 yen ($43) a bottle is nearly 30 times as expensive as ordinary milk even in Tokyo, which is famous for its high prices.

The milk is taken from cows once a week at the break of dawn as they discharge a lot of a stress-relieving hormone called melatonin during the night.

The milk is bottled within six hours of milking at a farm north of Tokyo and is said to contain three to four times as much melatonin as usual milk.
