“Good health must lie at the core of any successful response to ageing. If we can ensure that people are living healthier as well as longer lives, the opportunities will be greater and the costs to society less. Overwhelmingly the health challenges in older age are the consequences of non-communicable disease. We need to develop health systems which can provide the chronic care that these diseases and their risk factors require,” said Dr. Margaret Chan, Director-General of the World Health Organization (WHO) at the celebration of the World Health Day on April 7 in Geneva, Switzerland.
