The life so short, the craft so long to learn. - Hippocrates

[N]o less mischief happens to a man from unseasonable depletion than from repletion... to the bulk of mankind it is of little consequence which of these rules they observe... whether they make it a practice to take one or two meals [per day]. But there are certain persons who cannot readily change their diet with impunity; and if they make any alteration in it for one day, or even for a part of a day, are greatly injured thereby.

Time is that wherein there is opportunity, and opportunity is that wherein there is no great time. Healing is a matter of time, but it is sometimes also a matter of opportunity. However, knowing this, one must attend to medical practice not primarily to plausible theories, but to experience combined with reason. For a theory is a composite memory of things apprehended with sense perception.

Let food be thy medicine and medicine be thy food.
