The fact that improved health has an independent value for individuals implies that the health facilities available are an important item in the country's standard of living. At the same time, the availability of almost every other item of consumption including foodstuffs, housing, clothing, sanitation and educational facilities is relevant to health conditions. Improved health conditions should increase labour input and efficiency; they can in some circumstances also increase the acreage of cultivable land. The integration of health sector planning into a system of accelerating development may often confirm the belief that differences between the sound economic point of view and the bona fide humanitarian point of view are more apparent than real. In all events it will not be possible to ignore consistently either humanitarian or economic considerations ( Frederiksen, 1969) . The best way of ensuring health as an effective investment is to replace the older project-by-project approach to planning with integrated public investment planning, whereby health services and investments become integral parts of a multi-sectorial system for accelerating the development of the economy and society. Such integrated public investment plans start with individual projects which are combined into sector programmes and then into an investment plan for the public sector ( Waterston, 1969) . In this way, health would be associated closely with all other sector development and resources from the economic sector of the development budget would become available for the health sector. In the health sector much still has to be learned. Within the profession we have to be interested in health as well as disease. We have to be prepared to invest in health rather than continually to budget for disease. We have to develop communication with other disciplines and sciences, especially with the economist. As Klarman (1967) has shown, the problem of measurement still has to be tackled by both sides. It is for the economist, employing all of his traditional tools, plus those of the operations researcher and sociologist, to try to measure the value of the productive and consumption aspects of health services. It is for the epidemiologist and the clinical trial and survey to determine the effects produced by the investment in health. It is finally for the administrator to continue to strive for good balanced judgment in making decisions, especially when major elements of the cost-benefit calculations are missing, or when conflict exists between economic and health planning.
