I watched this happen to a guy from UK, he had lung cancer, no insurance, could have paid for hospital stuff but decided to let nature take it's course, so he only lived a few months. I also have no insurance, going back to America wouldn't help any because of not having insurance there either. We all know how expensive health care is in America anyway. So I bicycle about 250 KM a week and try to stay healthy (so far it's working and I'm 62). If I were to come down with cancer I too would most likely let nature take it's course as I've seen too many people go through treatments and get so sick from the treatments and have no quality of life, so basically just suffer and then die anyway in a short time, why not cut out that sickness from the treatments and maybe last longer without them. At least that's my thoughts maybe I'd change my mind if it happens.
