“The children now love luxury; they
have bad manners, contempt for
authority; they allow disrespect for
elders and love chatter in place of
exercise. Children now are tyrants,
not the servants of their households.
They no longer rise when elders
enter the room. They contradict their
parents, chatter before company,
gobble up dainties at the table, cross
their legs, and tyrannize their
teachers.”
Socrates

 1 in 4 sexually active adolescents will acquire an
STD before high school graduation
 1 in 5 Americans with AIDS were infected during
adolescence

interest in protective factors, such as family
connectedness, school connectedness and
spirituality, to offset risk factors
 youth development initiatives that focus on youth as
assets to be developed rather than problems to be
solved
