I left in the rain and it 's been gray or coming down most of the past two days . The various surges of aroma that typically shock your senses now hang in thick and constant in the humid air . Any long piece of travel in the Developing World can humble you , but overnight rides weaken you in a way reminiscent of heartbreak . You rush to make connections or get through border crossings - in my case walking , taking a taxi , two buses and a bicycle rickshaw to get to and over the Nepal / India boder .

Question: Why would a long piece of travel in the developing world humble a person ?
Answer: Because there are a lot of modes of transportation that must be taken .None of the above choices .Because there is a lot of rain in these environments .Because they 'll have a chance to see how the world 's poor people live .
