Difference between wise, ignorant and greedy.
he old man is uneducated and old. His head is bare as he ages, not much blocking his head and eyes. So he crosses the bridge without noticing its distance.
-- The second man is a greedy officer, he may be so drunk with bribe money that he will not see the bridge breaking. But will he be able to get through? Maybe yes or no. Whatever it is, he doesn't care, he just keeps running, aiming for the bag of money.
