The Virtual Wife, a new Japanese cell phone service, ensures that busy Japanese businessmen eat nutritiously even when their wife isn't there to remind them. The free service from Metabo-info sends four text messages a day to subscribers, encouraging them to watch their calorie intakes and avoid unhealthy foods. Men can choose from four wives, a professional woman, a "kind, pretty" housewife, a young "sporty" trendsetter, and a maid. No "virtual husbands" are available. [Inventor Spot]
