The main neurological system is wired up such that the best attention continues to be available if the remaining part for the mind is awake, and vice versa.
Disconcertingly, experiments revealed that the crocodiles had been especially more likely to keep an optical attention out whenever humans, in place of other crocodiles, were nearby.
