I agree with Ariel. I have never even pondered positive peace but always had what is defined above as “negative peace” in mind. Having learned the distinction between the two is great because it almost makes me more passionate about establishing it. It gives me motivation and incentive to not only strive for peace but ways to achieve it as well. I think it is important to educate people about these two categories because generally peace is such a simple concept. For some, it’s as simple as putting up your two fingers, as no war or even as mutual disagreement. Defining it in more specific terms and emphasizing the need for sustainability of peace is important because it will help people devise a plan of action for the peace they are working towards. I know it makes me think personally, that what can I do not to only achieve peace or promote peace, but how I can promote the maintenance of it as well. At the same time, I must bring us back to my first point…….most people strive for immediate satisfaction rather than a large delay reward, is it even our issue to worry about sustainability when we are so far from achieving peace in the first place.
Medical licenses are a limited commodity, reflecting an artificial shortage created by a partnership between Congress and organizations representing physicians—with medical school seats and residency positions effectively allotted by the government, much like radio frequencies. Physicians benefit from this arrangement in that a smaller number of physicians inevitably leads to increased rates of reimbursement. There's nothing inherently wrong with this arrangement. However, it belies any claim that doctors should have the same right to choose their customers as barbers or babysitters. Much as the government has been willing to impose duties on radio stations (., indecency codes, equal time rules) that would be impermissible if applied to newspapers, Montana might reasonably consider requiring physicians, in return for the privilege of a medical license, to prescribe medication to the dying without regard to the patient's intent. 
A number of studies have been done on optimism and psychological well-being. One study conducted by Aspinwall and Taylor (1990) assessed incoming freshmen on a range of personality factors such as optimism, self-esteem, locus of self-control, etc.  It was found that freshmen who scored high on optimism before entering college were reported to have lower levels of psychological distress than their more pessimistic peers, while controlling for the other personality factors. Over time, the more optimistic students were less stressed, less lonely, and less depressed than their pessimistic counterparts. Thus, this study suggests a strong link between optimism and psychological well-being.
