At 3,500 metres, La Paz, Bolivia, is the highest capital in the world．Many roads are in bad condition and accidents are frequent．One road in particular, is considered the most dangerous in the world．On one side there is a sudden drop, which is so great that anyone inside the vehicle is lucky to survive．
But thanks to one man, the death toll （人数） has fallen．Timoteo Apaza is a man who lives in a village near the most dangerous part of the road, known as "the Devil's Bend"．Timoteo has an unusual job — he is a human traffic signal．Every morning he stands on the bend and directs the traffic．When two vehicles approach from opposite directions, they can't see each other, but they can see Timoteo．Actually no one pays him to do the job．Sometimes drivers give him a tip so that he has just enough money to live on．But often they just pass by, taking the human traffic signal for granted．
So why does he do it? Before Timoteo volunteered to direct the traffic, he had been a driver．Then one day he was driving a lorry load of bananas when he came off the road at a bend and fell three hundred metres down the mountain．Somehow he survived, but was in hospital for months．Then, a few years later, he was called out in the night to help pull people out of a bus crashed at the Devil's Bend．This last experience had a profound effect on Timoteo．He realized that he was lucky to be alive himself, and felt that it was his mission in life to help others．So every morning, week in, week out, from dawn to dusk, Timoteo takes up his place on the bend．
