As a whole, the large body of research on the effects of Medicaid expansion under the ACA suggests that expansion has had largely positive impacts on coverage; access to care, utilization, and affordability; and economic outcomes, including impacts on state budgets, uncompensated care costs for hospitals and clinics, and employment and the labor market. With ACA repeal and replacement remaining a priority for the Trump Administration and Congress, these findings suggest that gains in coverage and access as well as economic benefits to states and providers are at stake if the Medicaid expansion is repealed.
There's no clear explanation for why people who practice positive thinking enjoy the above benefits but researchers feel that having a positive outlook just helps you better cope with things and focus on solutions instead of magnifying problems. They're just better able to manage stress and setbacks than those who are more pessimistic. Also, people who are optimistic are usually more active physically and as a result, will tend to be healthier and live longer. They also tend to eat better, avoid alcohol, sugars and are non-smokers, all of which helps them enjoy better health.
This is well demonstrated in the writings of Edward Abbey with particular regard to Desert Solitaire where solitude focused only on isolation from other people allows for a more complete connection to the external world, as in the absence of human interaction the natural world itself takes on the role of the companion. In this context, the individual seeking solitude does so not strictly for personal gain or introspection, though this is often an unavoidable outcome, but instead in an attempt to gain an understanding of the natural world as entirely removed from the human perspective as possible, a state of mind much more readily attained in the complete absence of outside human presence. In psychology, introverted individuals may require spending time away from people to recharge. Those who are simply socially apathetic might find it a pleasurable environment in which to occupy oneself with solitary tasks.
