Young adults engage in more risky events than any other developmental stage because, health- and physically-wise, they are at their peak.

Biosocial Development The biological and physical development of individuals during this stage tends to be in the best shape of their lives. They are able to cope with stress much more easily and are less susceptible to illness and physical problems. During these years, the organ system reserves of most individuals are at their peak performance, around 100 percent, and homeostasis is normal, but in adulthood, organ system reserves begin slowly to decrease. Often people in this stage tend to maintain the same unhealthy habits as in adolescence, mental processes often lead to changes through exercise and alternation of eating habits to achieve a more dignified physique.
