Suppose you have been up all night, and instead of being allowed to have your cup of tea, you were to be told that you ought to "exercise self-control," what should you say? Now, the nerves of the sick are always in the state that yours are in after you have been up all night. [Sidenote: Supply to the sick the defect of manual labour.] We will suppose the diet of the sick to be cared for. Then, this state of nerves is most frequently to be relieved by care in affording them a pleasant view, a judicious variety as to flowers,[21] and pretty things. Light by itself will often relieve it. The craving for "the return of day," which the sick so constantly evince, is generally nothing but the desire for light, the remembrance of the relief which a variety of objects before the eye affords to the harassed sick mind. Again, every man and every woman has some amount of manual employment, excepting a few fine ladies, who do not even dress themselves, and who are virtually in the same category, as to nerves, as the sick. Now, you can have no idea of the relief which manual labour is to you--of the degree to which the deprivation of manual employment increases the peculiar irritability from which many sick suffer. A little needle-work, a little writing, a little cleaning, would be the greatest relief the sick could have, if they could do it; these _are_ the greatest relief to you, though you do not know it. Reading, though it is often the only thing the sick can do, is not this relief. Bearing this in mind, bearing in mind that you have all these varieties of employment which the sick cannot have, bear also in mind to obtain for them all the varieties which they can enjoy. I need hardly say that I am well aware that excess in needle-work, in writing, in any other continuous employment, will produce the same irritability that defect in manual employment (as one cause) produces in the sick. VI. TAKING FOOD. [Sidenote: Want of attention to hours of taking food.] Every careful observer of the sick will agree in this that thousands of patients are annually starved in the midst of plenty, from want of attention to the ways which alone make it possible for them to take food. This want of attention is as remarkable in those who urge upon the sick to do what is quite impossible to them, as in the sick themselves who will not make the effort to do what is perfectly possible to them.
