Young Adulthood ( 1 ) EDUC P Young Adulthood: The period between 18‐ 25 Physical Development Cultural and National Differences Strong and Healthy Bodies: in good health A time for hard physical work and childbearing. Physical work and parenthood are no longer expected of every young adult in the twenty‐first century. emerging adults have reached full height (girls usually by age 16, boys by age 18). For both sexes, muscle growth and fat accumulation continue into the early 20s, when women attain adult breast and hip size and men reach full shoulder width and upper‐arm strength.

  • By age 20, the immune system has developed well enough to fight off everything from the sniffles to cancer.
  • Usually, blood pressure is normal, teeth develop no new cavities, heart rate is steady, the brain is fully grown, and lung capacity is as large as it will ever be.
  • Death from disease almost never occurs during emerging adulthood. Sex and Reproduction
  • The sexual-reproductive system is especially vigorous.
  • The sex drive is powerful, infertility is rare, orgasm is frequent, and birth is easy, with fewer complications in the early 20s than at any other time.
  • Sexual-reproductive characteristics are produced by sex hormones, which peak in both sexes at about age 20.
  • With frequent intercourse and without contraception, the average woman in her early 20s becomes pregnant within three months.
  • Globalization, advanced technology, and modern medicine produce effective contraception, available in almost every nation.
  • As fewer infants die, people no longer need to begin childbearing before age 20 or to have four or more children simply to ensure that some of their children will survive. Homeostasis
  • The adjustment of all the body’s systems to keep physiological functions in a state of equilibrium.
  • As the body ages, it takes longer for these adjustments to occur, so it becomes harder for older bodies to adapt to stress.
  • Nutrition and exercise underlie health at every age. Edgework
  • Occupations, recreational activities, or other ventures that involve a degree of risk or danger
  • The prospect of “living on the edge” makes edgework compelling to some individuals. Replacement Rate
  • The number of births per woman that would be required to maintain a nation’s (or the world’s) population with no increases or decreases.
  • The current replacement rate is considered to be about 2. births per woman.
  • Birth rates have declined the world over, with developing as well as developed nations recording lower fertility rates.
  • Advances in contraception have not only reduced the birth rate; they have also increased the rate of sexual activity, especially among unmarried adults.
  • This approach publicizes survey results to make emerging adults aware of the actual prevalence of various behaviors within their peer group. DOCSITY.COM
