Personal life is the course of an individual's life, especially when viewed as the sum of personal choices contributing to one's personal identity. It is a common notion in modern existence—although more so in more prosperous parts of the world such as Western Europe and North America.]citation needed[ In these areas, there are service industries which are designed to help people improve their personal lives via counselling or life coaching.
In the past, before modern technology largely alleviated the problem of economic scarcity in industrialised countries, most people spent a large portion of their time attempting to provide their basic survival needs, including water, food, and protection from the weather. Survival skills were necessary for the sake of both self and community; food needed to be harvested and shelters needed to be maintained. There was little privacy in a community, and people were identified by their social role. Jobs were assigned out of necessity rather than personal choice.
In mathematics and geometry, an osculating curve is an extension of the concept of tangent. A tangent line to a curve is the straight line that shares the location and direction of the curve, while an osculating circle to the same curve shares the location, direction, and curvature.
Two curves are said to be osculating at a particular point if they share the same osculating circle, just as they are said to be tangent if they share the same tangent line. The term derives from the Latinate root "osculate", to kiss, because the two curves contact one another in a more intimate way than simple tangency.
Human behavior refers to the range of behaviors exhibited by humans and which are influenced by culture, attitudes, emotions, values, ethics, authority, rapport, hypnosis, persuasion, coercion and/or genetics.
The behavior of people (and other organisms or even mechanisms) falls within a range with some behavior being common, some unusual, some acceptable, and some outside acceptable limits. In sociology, behavior in general is characterised as having no meaning, being not directed at other people, and thus is the most basic human action. Behavior in this general sense should not be mistaken with social behavior, which is a more advanced action, as social behavior is behavior specifically directed at other people. The acceptability of behavior depends heavily upon social norms and is regulated by various means of social control. Human behavior is studied by the specialised academic disciplines of psychiatry, psychology, social work, sociology, economics, and anthropology.
An interpersonal relationship is a strong, deep, or close association/acquaintance between two or more people that may range in duration from brief to enduring. This association may be based on inference, love, solidarity, regular business interactions, or some other type of social commitment. Interpersonal relationships are formed in the context of social, cultural and other influences. The context can vary from family or kinship relations, friendship, marriage, relations with associates, work, clubs, neighborhoods, and places of worship They may be regulated by law, custom, or mutual agreement, and are the basis of social groups and society as a whole.
The study of interpersonal relationships involves several branches of the social sciences, including such disciplines as sociology, psychology, anthropology, and social work. Interpersonal skills are extremely vital when trying to develop a relationship with another person. The scientific study of relationships evolved during the 1990s and came to be referred to as 'relationship science', which distinguishes itself from anecdotal evidence or pseudo-experts by basing conclusions on data and objective analysis. Interpersonal ties are also a subject in mathematical sociology.
