The Grant Study is an 85-year continuing longitudinal study from the Study of Adult Development at Harvard Medical School, started in 1938. [2] It has followed 268 Harvard-educated men, the majority of whom were members of the undergraduate classes of 1942, 1943 and 1944.
It has run in tandem with a study called "The Glueck Study," which included a second cohort of 456 disadvantaged, non-delinquent inner-city youths who grew up in Boston neighborhoods between 1940 and 1945. "The Glueck Study" was conducted in order to pinpoint predictors of delinquency. The participants were all white males and of American nationality. As of 2024 [update] , the men continue to be studied. [3] They were evaluated at least every two years by questionnaires through information from their physicians and by personal interviews. Information was gathered about their mental and physical health, career enjoyment, retirement experience and marital quality. The goal of the study was to identify predictors of healthy aging.
The study, its methodology, and results are described in three books by a principal investigator in the study, George Vaillant. The first book, Adaptation to Life, describes the study up to a time when the men were 47 years of age. [4] The second book, Aging Well, describes a time when the inner-city men were 70 years old and those of the Harvard group were 80. [5] In 2012, Vaillant and Harvard University Press published the third book, Triumphs of Experience, which shared more findings from the Grant Study. [6]
The study is part of The Study of Adult Development, which is now under the direction of Dr. Robert J. Waldinger [7] [8] at Massachusetts General Hospital.
The study is unique; partly because of the long-time span of the cohort, and also partly because of the high social status of some of the study participants. Among the most notable Grant Study participants included Ben Bradlee, an editor of The Washington Post , and US President John F. Kennedy. [9]
George Vaillant, who directed the study for more than three decades, has published a summation of the key insights the study has yielded in the book Triumphs of Experience: The Men of the Harvard Grant Study: [6]
In psychoanalytic theory, a defence mechanism is an unconscious psychological operation that functions to protect a person from anxiety-producing thoughts and feelings related to internal conflicts and outer stressors.

Erotic talk, also known as dirty talk, gross talk, love talk, naughty talk, sexting, sexy talk, talking dirty, or talking gross, is the practice of using explicit word imagery to heighten sexual excitement before and during physical sexual activity. It is commonly a part of foreplay, and can include vivid erotic descriptions, sexual humor, sexual commands and rude words. It may be whispered into a partner's ear, spoken over a telephone, or put into text. The intention of erotic talk is generally to generate excitement between one, both or all parties engaged in a sexual interaction, or even to induce orgasm.

In psychology, the theory of attachment can be applied to adult relationships including friendships, emotional affairs, adult romantic and carnal relationships and, in some cases, relationships with inanimate objects. Attachment theory, initially studied in the 1960s and 1970s primarily in the context of children and parents, was extended to adult relationships in the late 1980s. The working models of children found in Bowlby's attachment theory form a pattern of interaction that is likely to continue influencing adult relationships.

Environment and intelligence research investigates the impact of environment on intelligence. This is one of the most important factors in understanding human group differences in IQ test scores and other measures of cognitive ability. It is estimated that genes contribute about 20–40% of the variance in intelligence in childhood and about 80% in adulthood. Thus the environment and its interaction with genes account for a high proportion of the variation in intelligence seen in groups of young children, and for a small proportion of the variation observed in groups of mature adults. Historically, there has been great interest in the field of intelligence research to determine environmental influences on the development of cognitive functioning, in particular, fluid intelligence, as defined by its stabilization at 16 years of age. Despite the fact that intelligence stabilizes in early adulthood it is thought that genetic factors come to play more of a role in our intelligence during middle and old age and that the importance of the environment dissipates.
The Natural History of Alcoholism Revisited (1995) is a book by psychiatrist George E. Vaillant that describes two multi-decade studies of the lives of 600 American males, non-alcoholics at the outset, focusing on their lifelong drinking behaviours. By following the men from youth to old age it was possible to chart their drinking patterns and what factors may have contributed to alcoholism. Another study followed 100 severe alcoholics from a clinic eight years after their detoxification. The National Review hailed the first edition (1983) as "a genuine revolution in the field of alcoholism research" and said that "Vaillant has combined clinical experience with an unprecedented amount of empirical data to produce what may ultimately come to be viewed as the single most important contribution to the literature of alcoholism since the first edition of AA's Big Book." Some of the main conclusions of Vaillant's book are:
"Leisure refers to activities that a person voluntarily engages in when they are free from any work, social or familial responsibilities." Leisure satisfaction is the positive perceptions or feelings that an individual forms, elicits and gains as a result of engaging in leisure activities and choices. What can contribute to leisure satisfaction is to what degree an individual is currently satisfied with their leisure experiences and activities. An individual might attain positive feelings of contentment and happiness that result from the satisfaction of needs. Participation in leisure activities and leisure satisfaction are inextricably linked to an individual's health. Caldwell suspects that leisure activities may be associated with a number of defensive traits that enhance a person's resiliency to negative life experiences. Some aspects of leisure activities that can act as protective factors include: "[the activity] being personally meaningful, intrinsically interesting and/or challenging; offering social support and friendships; contributing to a sense of competence and/or self efficacy; offering a sense of personal control, choice and self-determination; and being relaxing and/or distracting the individual from negative life events." Leisure activities, although ranging in types, have also proven to be beneficial to health cross-culturally.

Whitfield was an American medical doctor in private practice specializing in assisting survivors of childhood trauma with their recovery, and with addictions including alcoholism and related disorders. He was certified by the American Society of Addiction Medicine, a founding member of the National Association for the Children of Alcoholics, and a member of the American Professional Society on the Abuse of Children.
In social psychology, illusory superiority is a cognitive bias wherein people overestimate their own qualities and abilities compared to others. Illusory superiority is one of many positive illusions, relating to the self, that are evident in the study of intelligence, the effective performance of tasks and tests, and the possession of desirable personal characteristics and personality traits. Overestimation of abilities compared to an objective measure is known as the overconfidence effect.
Sexual desire discrepancy (SDD) is the difference between one's desired frequency of sexual intercourse and the actual frequency of sexual intercourse within a relationship. Among couples seeking sex therapy, problems of sexual desire are the most commonly reported dysfunctions, yet have historically been the most difficult to treat successfully. Sexual satisfaction in a relationship has a direct relationship with overall relationship satisfaction and relationship well-being. Sexual desire and sexual frequency do not stem from the same domains, sexual desire characterizes an underlying aspect of sexual motivation and is associated with romantic feelings while actual sexual activity and intercourse is associated with the development and advancement of a given relationship. Thus together, sexual desire and sexual frequency can successfully predict the stability of a relationship. While higher individual sexual desire discrepancies among married individuals may undermine overall relationship well-being, higher SDD scores for females may be beneficial for romantic relationships, because those females have high levels of passionate love and attachment to their partner. Studies suggest that women with higher levels of desire relative to that of their partners' may experience fewer relationship adjustment problems than women with lower levels of desire relative to their partners'. Empirical evidence has shown that sexual desire is a factor that heavily influences couple satisfaction and relationship continuity which has been one of the main reasons for the interest in this research domain of human sexuality.
Alcoholism in family systems refers to the conditions in families that enable alcoholism and the effects of alcoholic behavior by one or more family members on the rest of the family. Mental health professionals are increasingly considering alcoholism and addiction as diseases that flourish in and are enabled by family systems.
Cognitive epidemiology is a field of research that examines the associations between intelligence test scores and health, more specifically morbidity and mortality. Typically, test scores are obtained at an early age, and compared to later morbidity and mortality. In addition to exploring and establishing these associations, cognitive epidemiology seeks to understand causal relationships between intelligence and health outcomes. Researchers in the field argue that intelligence measured at an early age is an important predictor of later health and mortality differences.
The activity theory of aging, also known as the implicit theory of aging, normal theory of aging, and lay theory of aging, proposes that aging occurs with more positive outcomes when adults stay active and maintain social interactions as they get older. Activity theory suggests that the aging process is slowed or delayed, and quality of life is enhanced when the elderly remain socially active. Book clubs, club sports, barbeques, volunteer work, fitness classes, brunch dates, holiday celebrations and protests are just a few examples of how people maintain a healthy social life, which the activity theory of aging reports contributes to overall health in later life.
In positive psychology, zest is among the discrete strengths people possess. Having zest means treating life as an adventure and feeling motivated in challenging situations. People with zest display enthusiasm, excitement, and energy as they tackle life's tasks. Zest is a component of the virtue of courage in some positive psychology paradigms.
Life satisfaction is an evaluation of a person's quality of life. It is assessed in terms of mood, relationship satisfaction, achieved goals, self-concepts, and self-perceived ability to cope with their life. Life satisfaction involves a favorable attitude towards one's life—rather than an assessment of current feelings. Life satisfaction has been measured in relation to economic standing, degree of education, experiences, residence, and other factors.
Subjective well-being (SWB) is a self-reported measure of well-being, typically obtained by questionnaire.
Robert J. Waldinger is an American psychiatrist, psychoanalyst, and Zen priest. He is a part-time professor of psychiatry at Harvard Medical School and directs the Harvard Study of Adult Development, one of the longest-running studies of adult life ever conducted.
Well-being is a multifaceted topic studied in psychology, especially positive psychology. Biologically, well-being is highly influenced by endogenous molecules that impact happiness and euphoria in organisms, often referred to as "well-being related markers". Related concepts are eudaimonia, happiness, flourishing, quality of life, contentment, and meaningful life.
