food, but should not be taken in
concentrated form into an empty stomach. Sweets are best taken at the
end of a meal, but in such cases the teeth should be well cleansed.
Fruit at the end of a meal tends to prevent any injury to the teeth from
sugar and starches.

Potatoes, cereals, bread and all starchy vegetables are fattening, but
should be well chewed and tasted before swallowing. Thin, anemic people
derive much benefit from egg lemonade or egg-nogs (without alcohol) made
from the yolks, which contain fat, iron and other valuable elements.

[Sidenote: Exercise for Underweight]

Overfatigue and exhausting physical exertion should be avoided.

Moderate systematic exercises, with deep breathing, and sleeping out of
doors, or approaching as near to it as one can, are advisable. At middle
life and after, underweight, unless extreme or accompanied by evidence
of impaired health, should not give any concern. Other things being
equal, the old motto "A lean horse for a long race," holds good.

SECTION III

NOTES ON POSTURE

[Sidenote: Corrective Exercises for Faulty Posture]

Among simple exercises recommended for strengthening the abdominal
muscles and restoring the organs to normal position are the following:

Lie flat on the back and rise to a sitting posture; squat until the
thighs rest upon the calves of the legs. Lie flat on the back, head
downward on an inclined plane (an ironing board, uptilted, will do) and
make a bridge at intervals by arching the abdomen and resting on
shoulders and heels.

From the fundamental standing posture described in this section, a
number of exercises can be developed.

1. _Yard-arm._--While deeply inhaling (through the nose) slowly raise
the arms to horizontal position, straight out from the sides; let the
arms fall slowly to the sides while exhaling. The chest should be well
arched forward, hips drawn backward and arms hung back of thighs while
performing this exercise.

These movements should be performed at the rate of about 10 per minute.

3. _Tree-swaying._--While in the standing position, thrust the arms
straight above the head, then sway from side to side, moving from the
hips upward, the arms loosely waving like the branches of a tree.
(Sargent.)

4. _Leg-lifting._--Assume the standing position, but with hands resting
on the hips. Raise the right thigh until at right angles with the body,
leg at right angles with thigh, thrust the leg straightforward to a
