Counsels to Parents, Teachers, and Students - Ellen G. White

studies and concentrate their minds upon the object
of obtaining an education. They work the brain, but
allow the physical powers to remain inactive. Thus
the brain is overworked, and the muscles become
weak because they are not exercised. When these
students are graduated, it is evident that they have
obtained their education at the expense of life.
They have studied day and night, year after year,
keeping their minds continually upon the stretch,
while they have failed to exercise their muscles
sufficiently. ...
Young ladies frequently give themselves up to
study, to the neglect of other branches of education
even more essential for practical life than the study
of books. And after having obtained their
education, they are often invalids for life. They
have neglected their health by remaining too much
indoors, deprived of the pure air of heaven and of
the God-given sunlight. These young women might
have come from school in health had they
combined with their studies household labor and
exercise in the open air.
