Tense? Frustrated? Anxious? Don't worry, Nakazawa Foods knows you live in a demanding, fast-paced society, and need to chill out. That's why they've invented "Adult Milk" -- a line of premium milk that supposedly reduce stress.

That is, if it doesn't stress you out to drop $43 for one quart of a dairy product. That's how much the Japanese company is charging for their new miracle drink -- 30 times what ordinary milk costs in Tokyo (which is already expensive).

The secret, apparently, is to take milk from cows only once a week, at the break of dawn. Because cows release melatonin (a stress-relieving hormone) during the night, this method will theoretically give you milk that has up to four times the normal amount of stress-relieving power.

Sounds relaxing -- if you can afford it.
