Some students put the whole being into their 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.
