Final answer:
John's good health is probably attributed to a robust support network from church involvement, increased stress management practices related to religious engagement, and the benefits of maintaining a consistent routine contributing to overall wellness.
Step-by-step explanation:
John's good health as an active member of his church for the past 35 years may be attributed to several factors. Specifically, access to a support network provided through his church involvement is a likely contributor to positive health outcomes. Social support has a well-documented connection to favorable health outcomes, as it can lead to better stress management, which includes both physiological benefits and the promotion of healthier lifestyle choices. Those with strong social relationships are noted to have a 50% greater likelihood of survival than those without. Furthermore, religious involvement is associated with increased practice using stress management skills, such as meditation and prayer, which can be beneficial for mental health. Lastly, the routine involved in consistent church attendance may also contribute to a consistent routine that can foster a stable and healthy lifestyle.
