The best ventilation is usually to be had through the windows. We advise
keeping windows open almost always in summer; and often open in winter.

Without habit, personality could not exist; for we could never do a

thing twice alike, and hence would be a new person each succeeding
moment
Without habit, personality could not exist; for we could never do a
thing twice alike, and hence would be a new person each succeeding
moment. The acts which give us our own peculiar individuality are our
habitual acts--the little things that do themselves moment by moment
without care or attention, and are the truest and best expression of our
real selves. Probably no one of us could be very sure which arm he puts
into the sleeve, or which foot he puts into the shoe, first; and yet
each of us certainly formed the habit long ago of doing these things in
a certain way. We might not be able to describe just how we hold knife
and fork and spoon, and yet each has his own characteristic and habitual
way of handling them. We sit down and get up in some characteristic way,
and the very poise of our heads and attitudes of our bodies are the
result of habit. We get sleepy and wake up, become hungry and thirsty at
certain hours, through force of habit. We form the habit of liking a
certain chair, or nook, or corner, or path, or desk, and then seek this
to the exclusion of all others. We habitually use a particular pitch of
voice and type of enunciation in speaking, and this becomes one of our
characteristic marks; or we form the habit of using barbarisms or
solecisms of language in youth, and these cling to us and become an
inseparable part of us later in life.
