This, of course, hurt his pride, but essentially he was greatly relieved. He made but slow improvement until through the munificence of Uncle Sam he was given a new start in life through the Vocational Reeducation Board. Like many other city men, he has dreamed of the "chicken farm" as the ideal occupation free from too much work and yet lucrative. This, of course, is a mistaken notion, but while learning the work he is happy and is slowly regaining his energy. What time will bring forth no one can tell, but this is certain: throughout his life he will have to rely on good habits, carefully adjusted to his energy, in order to protect himself from the bankruptcy that so easily comes on him. A philosophy of life which will help to control his irritability is necessary, and the intelligent of the hypokinetic irritable acquire the habits and the philosophy necessary for their welfare. Any neurologist could cite any number of such cases with varying traits of character, high intelligence or feeble-minded, controlled in morals or uncontrolled, happily or unhappily situated, whose central difficulty is an irritable and easily exhausted store of energy. They are easily excited and excitement burns them out; that is the long and short of their situation. Sex, love, hatred, anger, strain, fear in all its forms, illness,--all these and many other emotions and happenings may break them down. Such people, and those who care for them, must not make the mistake of thinking that rough handling, strenuosity, will cure what is apparently a fixed character. There is an irritable, high-energy type--irritable hyperkinetic--that is well contrasted with the foregoing. This explosive personality works by fits and starts but does not wear out, merely, as it were, settles down to his ordinary pace when he rests up. He is like a six-day bicycle racer who plugs along but every now and then sprints like mad for a few laps and then comes back to a pace that would kill the average rider. I shall not trouble to cite such a case, but I can think of at least one man of good attainments who is of this explosive hyperkinetic type. He responds to every demand with a burst of energy, and his quota of ordinary activities is simply appalling. Neglecting the further types of energy display for the simple reason that this quality shades off into every conceivable type and is also a part of every nature, we turn to the types of emotional mood display. With these it is necessary to consider excitability as well, and the most interesting beings are here our objects of study.
