english: Well, if our brain costs just as much energy as it should, and if we can't spend every waking hour of the day feeding, then the only alternative, really, is to somehow get more energy out of the same foods.
non_english: Pa, ako našim mozgovima treba energije koliko je potrebno, i ako ne možemo da provedemo svaki sat tokom dana, hraneći se onda je jedina mogućnost, zaista da nekako dobijemo više energije iz iste hrane.
