The idea of going on a trip that lasts for more than a year is a common one. People go by car, by walking or by foot. In so doing they discover a new side of life that they had not known before. The simpler the mode of transport the cheaper. In this case the traveller produced a timelapse of his hair growing over an extended period. You see not only the distance but also the companions for segments of that trip. It’s an interesting idea.
