In the marketing of literature, books for Young adults are roughly targeted for ages 12 to 18. In health and human development, young adulthood is considered to be the stage between adolescence and adulthood, roughly ages 15 to 24. In popular usage, "young adult" is sometimes simply a euphemism

Adolescence is the transitional stage of development between childhood and full adulthood (gender-specific manhood, or womanhood), representing the period of time during which a person is biologically adult but emotionally not at full maturity. The ages which are considered to be part of adolescence vary by culture. In the United States, adolescence is generally considered to begin around age 12-13, and end at 19-20. By contrast, the World Health Organization (WHO) defines adolescence as the period of life between 10 and 20 years of a ...

A twenty-something is a person in the age group 20 to 29. Such a person may be termed a vicenarian. Beginning in the late 1980s, however, the terms "twentysomething" and "thirtysomething" took on new meanings beyond their ordinary ones, as they were used to convey the idea that persons occupying these respective age brackets at that time in Western societies — particularly the United States — exhibited contrasting collective personalities and worldviews. The practice of using these two terms in this fashion appears to have been set in motion by the title of a popular American television drama n ...

A number of social scientists, including anthropologist Margaret Mead and sociologist Mike Males, have repeatedly noted the contradictory treatment of laws affecting adolescents in the United States. As Males has noted the US Supreme Court has, "explicitly ruled that policy-makers may impose adult responsibilities and punishments on individual youths as if they were adults at the same time laws and policies abrogate adolescents†...

Puberty is the stage of the human lifespan in which a child develops secondary sex characteristics as his or her hormonal balance shifts strongly towards an adult state. This is triggered by the pituitary gland, which secretes a surge of hormones into the blood stream and begins the rapid maturation of the gonads: the girl's ovaries and the boy's testicles. Girls tend to enter puberty a year earlier than boys. The onset of puberty in girls is also related to body fat percentage. In most Western countries, the average age of menarche fell in a secular trend over the last century, most likely due to improved ...

The word preteen describes a child a bit younger than a teenager; perhaps between the ages of about 8 and 12. The neologism tween has the same meaning, but isn't in general use as either a colloquial or scientific term. This word comes from the age being between that of a young child and a teenager. Preteens are increasingly a specifically targeted market segment by business, because they tend to maintain the preferences they develop at this age. Even mobile phones are targeted toward this group. Also, because pre ...

In commerce, this generation is seen as an important target. Cellular phones, contemporary popular music, movies, television programs, video games and clothes are heavily marketed and often popular amongst adolescents.

Maturity in body leads to an interest in sexual activities, sometimes leading to teenage pregnancy. Since teens may not be emotionally mature enough or financially able to support children, the latter is usually considered problematic. At this age there is also a greater probability of drug and alcohol use, or mental health disorders such as schizophrenia, eating disorders and depression. The unstable emotions or lack of emotional intelligence among some adolescents may also lead to youth crime. Searching for a unique ide ...

Some adolescents and adults believe that people between the ages of 10 and 18 (or 21 or 25) are subjected to unjust discrimination. This form of discrimination is increasingly referred to as adultism. It is also called ageism, though that is simply prejudice on the grounds of age, not youth particularly. The underlying notion is that adolescents should be treated with equal respect as individuals by adults, institutions, and the law on the basis of their humanity, rather than being seen as "second-class citizens," intellectually inferior, or ...

Development begins with fertilization, the process by which the male gamete, the sperm cell, and the female gamete, the oocyte, fuse to give rise to a diploid cell, the zygote. In medicine, pregnancy is defined as beginning when a fertilized zygote becomes implanted in a woman's uterus. This occurs when the zygote then becomes embedded into the endometrium (lining of the uterus) where it forms a placenta, for the purpose of receiving essential nutrients through the uterus wall. The umbilical cor ...

Main article: Senescence In biology, senescence is the state or process of ageing. Cellular senescence is a phenomenon where isolated cells demonstrate a limited ability to divide in culture. Organismal senescence is the ageing of organisms. Organismal ageing is generally characterized by the declining ability to respond to stress, increasing homeostatic imbalance and increased risk of disease. Because of this, death is the ultimate consequence of ageing. Some researchers are treating ageing as a "di ...
