A<unk>  is someone in isolation who hides away from the attention of the public, a person who lives in solitude, i.e. seclusion from intercourse with the world. The word is from the Latin<unk> re, which means "shut up" or "sequester".
A person may become a<unk>  for many reasons: a celebrity may seek to escape the attentions of his or her fans; a misanthrope may be unable to tolerate human society; a survivalist may be practicing self-sufficiency; and a criminal might hide away from people to avoid detection by police. It can also be due to psychological reasons, such as: apathy, an autism spectrum disorder, a phobia, schizoid personality type, or due to avoidant personality disorder. A<unk>  can also be considered as a loner.
Some may become a<unk>  due to a physical deformity that makes their outward appearance unsettling to others. A person may also become a<unk>  for religious reasons, in which case he or she is usually referred to as a hermit or an anchorite.<unk> veness does not necessarily connote geographical isolation. A<unk>  may live in a crowded city, but infrequently leave the security of his or her home. However, isolated and sparsely populated US states (e.g., Montana, Wyoming, and Alaska) often harbor<unk> s, who are often seeking complete escape from civilization.
In Japan, an estimated 1.2 million people suffer from psychological problems which cause<unk> ve behavior. The phenomenon of "Hikikomori" or "social withdrawal" has become a major problem, often blamed on Japan's education system and social pressure to succeed.
