What I want to do in the future

When I become a nurse I wish to work in a variety of settings and definitely travel to different parts of the world. However, I would first like to work in downtown Toronto because I have visited various hospitals in that area and would like to visit these hospitals again. After I get some experience I would like to go to a third world country and provide care for those who are truly in need. I do not have a preference as to the country I would like to just go to, just any third world country. Lastly, I would like to continue my nursing experience and retire at a hospital in England. I have always loved the health care system in Europe and would love to be a part of that one in the future.
