You can see this most clearly when you take away someone's watch and you shut them into a bunker, deep underground, for a couple of months. (Laughter) People actually volunteer for this, and they usually come out kind of raving about their productive time in the hole.
To možete najbolje vidjeti kada nekome uzmete sat i zatvorite ga u bunker, duboko pod zemljom, nekoliko mjeseci. Ljudi se čak dobrovoljno javljaju za ovo, i obično izlaze nekako buncajući o svom produktivnom vremenu u rupi.
