Korea has become a leader in healthcare, with a strong emphasis on preventative measures and a focus on maintaining a healthy lifestyle. The traditional Korean diet is rich in nutrients and low in fat and cholesterol, while physical activity is promoted through sports and outdoor activities. Korea has a universal healthcare system that provides affordable healthcare to all citizens, and there is a cultural expectation to take responsibility for one's own health. Smoking rates have been declining due to public health campaigns and government regulations, while excessive alcohol consumption is being addressed through strict laws. Life expectancy is among the highest in the world, but challenges such as rising obesity rates and negative impacts of technology on mental health still need to be addressed.
