A huge factor, just saying- is how happiness pays a tremendous role in the health of an individual.
For example: I have often heard that success should not be valued by how much you earn or make in terms of money. I think of success as a term in which each or his own defines a meaning to it. Although, words such as achievement, accomplishment and desired outcome can all be used to describe success that may or may not involve them numbers after the dollar sign. When people coin a phrase of success, it may be because that the desired outcome of individual or individuals are doing what is wanted to be done or completed by a larger group of superiors. in the physical realm. That so called success, may not include money or the other benefits that come with a successful situation. Has anyone ever said that they were successful by relying on the government and other programs by the state in which they live in, to put housing over their heads, food in their mouth and other needs that have not been received due to being successful but unable to financially support themselves because their job or employment success has somehow managed to not include or enable them to afford a place to live this means paying rent, health insurance of al kinds, food, transportation, clothing and the other necessities? Perhaps. We have to ask ourselves if it is truly possible to make everyone happy or at least content with their life. Co-existence-just saying! Physicians are always wanting everyone to be healthy or at least that's their job, the rest of the nonsense that would be up to the individual. But where physicians fail, is that they don't see that the underlying lack of happiness can affect a person's physical health. You may not need medications or a psychiatrist but just to do things or be surrounded by what makes the person happy anything else is most likely pleasing to someone other than yourself.
Do the physical powers that be want optimal health which includes happiness? Probably not because they want it only for themselves. Which means that when you visit a physician, yes your vital measurements and what you can do to improve them will be what the physicians primary focus is; but what makes one truly happy or it's achievement, a physician may not be equipped to provide that happiness. Sometimes happiness involves being around what makes one happy. Any benefit received afterwards would be considered success. If in a situation where you are unhappy and in that physical occupation of unhappiness you receive no benefit and therefore no success has been attained except unto those of the physical power because this is where they achieve their most satisfaction, happiness and most of all many of these situations enable them to transfer the excess of wealth or accomplishment to those to which they would like to have.
It would be quite interesting to find if many people are happy and if not then they have poor happiness health. Back in the day and still present today, when asked what is going on? Many can still say nothing but the rent. Now measure that for happiness and health!
