The health of the individual at this time is usually good; susceptibility
to the diseases peculiar to childhood is slight, but there is increased
danger of acquiring adult diseases, and some writers claim that it is
during this time, when there are great physical disturbances, that the germ
of many adult diseases, such as tuberculosis, are apt to be implanted.
During the early part of this period it is unwise and dangerous for girls
to take part in such strenuous athletic games as basketball, or for boys to
indulge in football. Later when strength and equilibrium have been
restored, these games may be practiced without danger.

But the greatest of all changes, the one fundamental to adolescent life, is
the development of the sex instincts. Fortunate is the youth or maiden
whose parents are sensible and wise enough to instruct them concerning the
nature and purpose of these functions. Good books, such as "What a Boy
Should Know," and "What a Girl Should Know," are invaluable during this
critical time. This sudden ripening of the sex instinct is the cause of the
metamorphosis from childhood to early manhood and womanhood, and is the key
which explains the changes that characterize adolescence.

Emotionally, there is a tremendous awakening. The individual begins to feel
for the first time that he is actually alive and living; heretofore, life
has been a self-centered, matter-of-fact existence; now it enlarges and
becomes charged with intense feeling and significance. "Fear, anger, love,
pity, jealousy, emulation and ambition are either new-born or spring into
intense life."--James. All of these may be termed social instincts and they
imply a widening of the youth's horizon and include a "consciousness of
kind" that has heretofore been lacking.

Now, the youth or maiden truly falls in love; up to this time, regard for
the opposite sex has been merely a light fancy, barely skin deep; but now
it takes hold of the heart strings and plays upon them with an agony that
is truly heart rending. Who is there with red blood in his veins that does
not look back upon his first heart conflict with almost pathetic reverence?
Parents should be more concerned than they usually are over the conquest of
the heart of youth. Such affairs may carry with them consequences which are
more serious than could be anticipated.

At this time the youth or maiden is exceedingly resentful
