1. Living in a city

2. Excessive weight

3. Participating in team sports

4. Having a balanced diet

The correct answer is: Excessive weight

Excessive weight is identified as one of the major factors that can significantly reduce an individual's life span. Numerous studies have established a strong link between obesity and various health risks, such as cardiovascular disease, diabetes, and certain types of cancer. These health conditions can lead to a decrease in life expectancy and overall quality of life. Maintaining a healthy weight is crucial because it helps reduce the risk of chronic diseases and promotes better physical health. Obesity places additional strain on the body's systems, which can lead to early onset of health issues, making weight management an important aspect of long-term well-being. This understanding emphasizes the importance of lifestyle choices, including diet and exercise, in promoting longevity. In contrast, factors such as living in a city, participating in team sports, and having a balanced diet are generally associated with either neutral or positive effects on health. While living in a city may present unique stressors or health challenges, it does not inherently lead to reduced life expectancy. Engaging in team sports can foster physical activity and social connections, which are beneficial for health. A balanced diet is essential for maintaining health and preventing diseases, further supporting a longer life span.
