11.  In legislation and social organization, proceed on the principle that invalids, meaning persons who cannot keep themselves alive by their own activities, cannot, beyond reason, expect to be kept alive by the activity of others.  There is a point at which the most energetic policeman or doctor, when called upon to deal with an apparently drowned person, gives up artificial respiration, although it is never possible to declare with certainty, at any point short of decomposition, that another five minutes of the exercise would not effect resuscitation.  The theory that every individual alive is of infinite value is legislatively impracticable.  No doubt the higher the life we secure to the individual by wise social organization, the greater his value is to the community, and the more pains we shall take to pull him through any temporary danger or disablement.  But the man who costs more than he is worth is doomed by sound hygiene as inexorably as by sound economics.

12.  Do not try to live for ever.  You will not succeed.

13.  Use your health, even to the point of wearing it out.  That is what it is for.  Spend all you have before you die; and do not outlive yourself.

14.  Take the utmost care to get well born and well brought up.  This means that your mother must have a good doctor.  Be careful to go to a school where there is what they call a school clinic, where your nutrition and teeth and eyesight and other matters of importance to you will be attended to.  Be particularly careful to have all this done at the expense of the nation, as otherwise it will not be done at all, the chances being about forty to one against your being able to pay for it directly yourself, even if you know how to set about it.  Otherwise you will be what most people are at present:  an unsound citizen of an unsound nation, without sense enough to be ashamed or unhappy about it.
