Dimethyltryptamine
Dimethyltryptamine (DMT) is an indole alkaloid and a derivative of tryptamine (a metabolite of the essential amino acid tryptophan), which exists in many biological systems (endogenous substance) including plants and animals. DMT produces intense but short-lived (up to 30–60 min) psychedelic and hallucinogenic experiences. There is also increasing evidence that endogenous DMT plays a role in the central (CNS) and peripheral nervous system (PNS), and it may act as a neurotransmitter by acting as a non-selective serotonin agonist principally on the 5-hydroxytryptamine (5-HT1A and 5-HT2A) receptors.

Occupational Stress
Occupational stress is psychological stress related to one's job. Occupational stress refers to a chronic condition. Occupational stress can be managed by understanding what the stressful conditions at work are and taking steps to remediate those conditions. Occupational stress can occur when workers do not feel supported by supervisors or coworkers, feel as if they have little control over the work they perform, or find that their efforts on the job are incommensurate with the job's rewards. Occupational stress is a concern for both employees and employers because stressful job conditions are related to employees' emotional well-being, physical health, and job performance. A landmark study conducted by the World Health Organization and the International Labour Organization found that exposure to long working hours, which are theorized to operate through increased psycho-social occupational stress, is the occupational risk factor with the largest attributable burden of disease, according to these official estimates causing an estimated 745,000 workers to die from ischemic heart disease and stroke events in 2016. A number of disciplines within psychology are concerned with occupational stress including occupational health psychology, human factors and ergonomics, epidemiology, occupational medicine, sociology, industrial and organizational psychology, and industrial engineering.

Post-Pandemic Stress Disorder (COVID-19)
 The COVID-19 pandemic has undoubtedly affected the mental health of the population to a great extent and even left a permanent mark on it. Because the fear of something unknown, which is certainly the pandemic of a new coronavirus announced by the World Health Organization (WHO) on 11 March 2020, contributes to the manifestation of anxiety symptoms in society, it thus initially worsens the state of mental health, even of healthy people.

Mediterranean Diet
The Mediterranean diet is a food pattern incorporated into a set of lifestyle practices typical of Greece and Southern Italy in the early 1960s, where adult life expectancy was notably high, while rates of diet-related chronic diseases were low. The Mediterranean diet was described initially by the work of LG Allbaugh, commissioned by the Rockefeller foundation and the Greek government post-WW2 on the Greek island of Crete in 1948. The Mediterranean diet was accepted as Intangible Cultural Heritage of Humanity by UNESCO in 2013. The primary advantages of the Mediterranean diet include health benefits pertinent to cardiovascular, metabolic syndrome, and cognition.

Concept of Human Flourishing
Human flourishing is a thriving concept, whose use has greatly increased among academic researchers from a variety of fields, from the arts and humanities and psychology to the social and environmental sciences and economics. The rise of the concept was sparked by the positive psychology movement, which based it primarily on subjective and individual well-being; however, it was soon taken up by other currents, such as capabilities theory, reaching many social and collective concerns. Since 2016, the philosophical roots have especially energized the concept, maintaining the expansion of its use in fields related to the application of knowledge and management.

Social Isolation and Loneliness during the COVID-19
The COVID-19 pandemic has resulted in a predominantly global quarantine response that has been associated with social isolation, loneliness, and anxiety. Notwithstanding the efficacy of quarantine as a tool to limit the spread of disease, it also creates social isolation. Social isolation is an objective state in which an individual is alone, and is a sufficient, but not necessary, condition to produce the subjective feeling of loneliness. More specifically, some individuals may be socially isolated but experience this as a natural and healthy state in normal conditions; however, the prolongation of social isolation, particularly in unnatural conditions (e.g., in response to a global pandemic) can become a hazardous state to individual health. Loneliness is a similar yet distinct case: it is a subjective state in which a person feels that their social connections are inadequate (even though they may have a substantial social network). Both of these concepts relate to social connections and the maintenance of a healthy support network. The health implications of social isolation and loneliness during quarantine have a heterogenous and comorbid nature and, as a result, form a link to anxiety.

Mental Health of Self-Employed
We included 26 (three longitudinal and 23 cross-sectional) population-based studies of good quality, with data from 3,128,877 participants in total. A Swedish national register evaluation with 25 years follow-up, showed a higher incidence of mental illness among the self-employed compared to white-collar workers, but a lower incidence compared to blue-collar workers. In the second longitudinal study from Sweden the self-employed had a lower incidence of mental illness compared to both blue- and white-collar workers over 15 years, whereas the third longitudinal study (South Korea) did not find a difference regarding the incidence of depressive symptoms over 6 years. A higher prevalence of mental disorders among the self-employed compared to employees was true for the Asian and older European cross-sectional studies. However, most of the European cross-sectional studies from the last decade found lower or similar prevalence estimates among the self-employed. The majority of the American and Australian cross-sectional studies found a similar prevalence of mental disorders among the self-employed and the employees.
