Servando (B)

A new research realized in Harvard University, shows people spend half of their time daydreaming, and they say that their mind wandering is a sign of unhappiness. Over 2200 volunteers participated in this publishing, and they downloaded an iPhone app, where they sent more than 250000 messages during 24 hours. This research concludes that us spend more than 46% of our waking hours thinking in our past, and the researchers said, we are a unhappy mind.
