When I think of health, I think of being comfortably happy. Having no sickness or pain, with an understanding of your well being and any problems that might happen to your body is the part of being comfortable. The happy part is being happy with yourself physically, emotionally, intellectually and mentally. When illness comes to mind I think of something that cause you not to be comfortably happy when living your life form day today. It will affect the way you think, the way you feel, and your attitude towards certain things.
My criteria for the definitions came from personal and social reference. I feel that your health depends on how you live your life, if you consider it worth living and your thoughts about it are positive with no thoughts or feelings of harm being near, then you are in good health. But that can change to illness if you feel that there is a threatening harm to your life and you can not focus on your thoughts and understanding in life and might be going through some pain.
For example with anxiety I do feel like it is an illness because it can make you uncomfortable, fearful, and unease about life when you are in that state. Sometimes people don’t have control over their well-being and are unsure of how to calm and relax themselves back to a healthy state when going through this illness. It is not something that the body can handle naturally. If I compare anxiety to menstruation, I would categorize menstruation as an illness only if it didn’t happen naturally to the body. It does not cause angry thoughts, or something that is life threatening, if it happens regularly/normally, I do believe that is a sign of good health.
