## **Core Concept**
The World Health Day slogan is an annual theme set by the World Health Organization (WHO) to raise awareness about a specific health issue. Each year, the WHO selects a theme that highlights a priority area of public health concern. For World Health Day 2012, the focus was on the rising burden of **non-communicable diseases (NCDs)**, such as heart disease, diabetes, and chronic lung disease.

## **Why the Correct Answer is Right**
The correct slogan for World Health Day 2012 was "Ageing and health." This theme emphasized the impact of **ageing** on health, particularly the increase in **non-communicable diseases (NCDs)** as populations age. The WHO aimed to promote healthy ageing and encourage governments to create policies that support the elderly in maintaining their health and well-being.
