by According to a study published in the journal PLOS ONEa studyinteracting with people who are moderately active can make sedentary peoplemore active. The researchers developed a mathematical model that simulates how social interactions affect the movement trends of a population over time. Model simulations suggest that in the absence of social interaction, people experience a chronic individual decrease in physical activity and sedentary behavior begins to dominate. However, when the simulation included social interactions between sedentary and moderately active people, sedentary people became more active in the long term. Nonetheless, in the simulations, moderately active people were sedentary for longer and longer, and overall physical activity trends declined sharply.
