Being on the road for two years can take its toll on you from time to time. Sitting in a truck for several hours a day can wreak havoc on your body. Rebels, roadblocks, customs agents, shipping companies and border guards can all easily elevate stress levels. Bedding down in a different place nearly every single night can throw a wrench in your sleep patterns and being away from friends and family for such a long duration can make you homesick and depressed. All of our positive experiences and encounters throughout the course of the expedition significantly outweigh the not so glamorous ones, however, the bottom line is that the expedition can at times be a roller coaster ride of energy levels and emotions.
