Health issue seems a big issue anywhere in the world since it is killing most of the people of the world. One of the most dangerous health problems is cancer and it kills people who are rich or poor. I am not an expert when it comes to cancer but I could say that the bet way to cur this is to prevent this. A lung cancer can be prevented if only people will not use cigarettes in the first place.
Another health concern would be diabetes since many are beginning to have this because of poor activity. Among the ways that a diabetic could die is by cardiac arrest, kidney failure and many more. I am not sure if cardiac surgery could prevent it from happening but one thing is sure that you need to control your blood sugar problem in order avoid this.
