Which factor is associated with higher self-rated scores on living a worthwhile life?

The association of greater upper body strength with higher self-rated scores on living a worthwhile life can be understood through several dimensions of health and well-being. Strong upper body muscles are often indicative of overall physical fitness, which not only enhances physical capabilities but can also contribute to improved mental health, self-esteem, and quality of life.

Having physical strength allows individuals to engage more fully in activities they enjoy, such as sports, hobbies, and social gatherings, leading to a more active and satisfying lifestyle. This physical empowerment can foster a sense of autonomy and control over one's life, which is critical in contributing to feelings of worthiness and fulfillment.

Moreover, physical strength can be linked to better health outcomes and reduced risk of disease and disability, which can further enhance one's perception of life's value. Strength training has also been shown to have psychological benefits, such as reducing symptoms of anxiety and depression, thus reinforcing the connection between physical strength and subjective well-being.

These aspects underscore why greater upper body strength would be positively associated with perceiving life as worthwhile, reflecting a holistic view of health that encompasses both physical and psychological dimensions.
