If time allowed, I want to continue the project: to learn more about the impacts of ‘noise’ on human mental health, after all, the case of  ‘noise’ is somehow similar to   that of leading cause of death, it keeps at the top position for some reason. I want to finish the mental health care center geo-special analysis, although it’s not directly relates to answer the research question, however, it’s a good practice of coding. If I can get more informative data, from other fields to view the question again, I really want to get some linear regression work done.
