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: Če nas možgani stanejo toliko energije, kot bi nas morali in če ne moremo preživeti vsake sleherne ure za hranjenje, potem je edina alternativa dobiti več energije iz enake hrane.
