A study published in The Lancet estimated that poor diet contributes to approximately 11 million deaths worldwide each year.

Excessive alcohol consumption poses severe risks not only for liver damage but also increases vulnerability towards mental health disorders like depression or anxiety disorders while impairing cognitive function over time.

5. Environmental Factors:
Air pollution has become a grave concern worldwide due to its adverse effects on respiratory health; it can lead to asthma exacerbations or even lung cancer development over time if exposed continuously.

In conclusion, understanding health risk factors is crucial for maintaining optimal well-being throughout life's journey. By acknowledging these silent assassins such as sedentary lifestyles, poor diets, tobacco use, excessive alcohol consumption, and environmental factors, we can take proactive steps to mitigate their impact. Embracing a healthy lifestyle that includes regular physical activity, a balanced diet, abstaining from harmful substances like tobacco and excessive alcohol consumption while advocating for cleaner environments will undoubtedly lead to improved health outcomes for individuals and society as a whole.
