I really don't understand where you guys came to the conclusion that wealth = unhealthy. It is very far from the truth. In fact it is the opposite.

Below is an extract from the article:

"Yes, the rich really are different. They have better health. Not only do they enjoy greater longevity, but their days are less burdened by disease. Don't be fooled by the old idea that more money creates more problems. When it comes to health, the poor are much more likely to suffer physical and mental indignities—everything from asthma and accidents to chronic conditions like diabetes, high blood pressure, and heart disease. The lower your position in the economic hierarchy, the more susceptible you are to virtually every major disease affecting men."

So dont retire hastily. Ensure you have financial security first before retiring. If you are already unwell, find out the root cause of your illness. If it is indeed work related, change the work or job. Dont choose retirement as a first option. If your illness is due to something else then it makes even more sense to stay in employment as your medical expenses can be offset by your employment medical benefits and insurance. If you retire then you will have to bear all the medical expenses by yourself.
