"It is incredible how important it is that the corporeal frame should be kept under the influence of constant, continuous, and unbroken order, and free from the impressions of vicissitude, which always more or less derange the corporeal functions. After all, it is continued temperance which sustains the body for the longest period of time, and which most surely preserves it free from sickness."
