"So, when the patient turns up with an overworked and exhausted organ of some sort within him—be it what it may—heart, brain or stomach—the true physician prescribes, first and chiefly, not drugs, but rest.
"Now, this is generally the advice the patient doesn't want. His desire is for a bottle of something, no matter how nasty it may be, which shall ' fix him up,' and let him go on doing what he has been doing previously. Common-sense is always at a discount, and never more so than in this case. The tired brain-worker doesn't want to stop. Give him something to whip up his brain and his body, something to drive the spurs into them.

They insist 'that the strength must be kept up,' and would like to force the patient to eat more than he does when well.' You will let
