If I had the opportunity to go to another country as an exchange student, then I would probably have refused. I always miss my friends and loved ones, going for a long time. Another thing, if I went there to relax for a while. It would be interesting. You can learn a lot, to be charged with emotions,improve language skills. I believe that to go away somewhere for a long time is stressful for humans, but moderate rest-the best that can be.
