  • Adde to this diſsipated and diſtracted ſtate of Miniſters, their private diſtreſſes and poverties, together with the publick neglect and indifferency of people toward them; who can wonder if they look pitifully one on another, which no jocoſe or juvenile drolings can relieve?

  A prepubescent child.

  • One patient, a pedophile with a long history of arrests, penal incarceration, psychiatric admissions, and outpatient psychotherapy, commented that in the past when he saw a juvenile male playing, he (the patient) would without hesitation approach the boy and make a sexual proposition. When he was on MPA [medroxyprogesterone acetate] therapy, he stated that, at worst, when he saw such a juvenile, he only smiled "with appreciation" for the boy's good looks and otherwise kept about his business.

  biologynatural-scienceszoologyA sexually immature animal.

  • Even if juveniles acquire sex-specific adult-like foraging skills before reaching adult size, their smaller body size may put them at a foraging disadvantage. […] The size effect on foraging is reduced in species that use small or easily manipulated substrates. For instance, in Costa Rican squirrel monkeys, juveniles apparently mastered techniques for insect foraging only a few months after weaning, when they were still much smaller than adults[…].

  A two-year-old racehorse.

  • Even more incredible is the legion of two-year-olds who win handsomely as juveniles and then disappear from the racetrack.
  • Professional trainers foster young horses with obvious potential. Instance the way Sir Michael Stoute uses patience to bring along his two-year-old colts and fillies at Newmarket, or the careful approach taken with juveniles by that wonderful conditioner Charlie Whittingham in California.
