...health?
Though health is the greatest wealth, still we have already discussed that certain 'aspects' of it are more or less earthily 'buyable'.
However, you can also view this issue in different light. One cannot build his or her hopeful heavenly castles out of earthy pills and paint one's dreams or strivings in colourless medical mixtures. Neither a person can be happy if whenever he or she goes (Sweden, Germany, USA etc.) all doctors are helpless because the disease seems to be incurable. In some cases neither pills nor operations can help to retrieve the long-lost health or even its few last fading sparkles. Besides, such existence (i.e. when you are taking medicine non-stop) only turns people's lives into constant suffering and burden.
All these thoughts give the green light for us to state that health is fundamentals of Happiness. When we are healthy and do not feel any pain we are open for all emotions like love, joy, inspiration and carelessness. However, when we are in physical pain, all we seem to need and want is for it to go away. It's simple as that, such an elementary axiom of life which requires no evidence of the fact that there's no happiness without good health!
When there's no health people are no longer able to savour power either – one of the tastiest pieces of the cake of Happiness. They simply do not give a damn about life's little pleasures like being silly, having fun, eating well, dancing the nights away. All their wishes and dreams reduce to one and only thing – waking up one day without feeling constant pain.
When people are hopelessly sick they would give everything to bring their health back to them. They no longer need money or great love, all values shift their positions when health fades away. When people are completely healthy, they don't always appreciate this true wealth of theirs and often start making up extra problems letting their eager sense of drama live upon them. That's why we should cherish our health and try to save it at least from things that we can control i.e. prevent our health from being wrapped up in cigarette smoke or from getting drowned in a life-size glass of alcohol. In order not to acutely feel that health equals happiness only after you've lost the latter and i.e. both, you should invariably take care of your psychological and physical condition.
Let's say you have so much money that you cannot even count it – not because you're bad at counting but because the amount is really uncountable. You also have recently found the greatest love of your life, the one which is worth living for. A pleasant bonus is that you are a powerful politician or businessman i.e. control a huge part of other people's lives as well which is always pleasant. You can have whatever you want the amount of it suggesting boundlessness. Bud suddenly, under some highly shocking circumstances, you need to make a choice between all that you have (according to the above-enumerated things) on the one hand and your Health on the other. No doubt, you'll choose Health in case it is within a hairbreadth of disaster.
