There was a study I particularly liked in which a group of depressed and a group of non-depressed people were asked to play a video game for an hour, and at the end of the hour, they were asked how many little monsters they thought they had killed.
Jedno mi se istraživanje osobito svidjelo. U njemu su skupina depresivnih  i skupina nedepresivnih ljudi trebale sat vremena  igrati video-igricu, a kad je taj sat istekao, pitali su ih da procijene  koliko su malih čudovišta ubili.
