I'm a mathematician at the University of Chicago, and I travel every moment I'm not teaching. I've lived for short times (a month or so at a time, usually in repeat visits) in a number of different places - Singapore, Istanbul, Bucuresti, Budapest, HCMC. I travel to clear my head to do my math research, to meet new people, and to understand this world. (And they don't have the two other languages I speak on their list: Romanian (fluently) and BCS (near-fluently))
