Question: Health and wealth. An article entitled "The Health and Wealth of Nations" says:

The positive correlation between health and income per capita is one of the best-known relations in international development. This correlation is commonly thought to reflect a causal link running from income to health. Recently, however, another intriguing possibility has emerged: that the health-income correlation is partly explained by a causal link running the other way-from health to income.

Explain how higher income in a nation can cause better health. Then explain how better health can cause higher income. There is no simple way to determine the direction of the link.
