The resulting regularity has an excellent effect upon the physical welfare of the worker.

2. Habits, under Scientific Management,

(a) are prescribed by standards. The various physical habits of the man, the motions that are used, having all been timed and then standardized, the worker acquires physical habits that are fixed.

(b) are taught; [1] therefore they are not remote but come actually and promptly into the consciousness and into the action of the worker.

(c) are retained, because they are standard habits and because the rewards which are given for using them make it an object to the worker to retain them.

(d) Are reënforced by individuality and functionalization;

that is to say, the worker is considered as an individual, and his possibilities are studied, before he is put into the work; therefore, his own individuality and his own particular function naturally reënforce those habits which he is taught to form. These habits, being scientifically derived, add to physical improvement.

3. Physical development

(a) is fostered through the play element, has been scientifically studied, and is utilized as far as possible; the same is true of the love of work, which is reënforced by the fact that the man has been placed where he will have the most love for his work.

(b) is insured by the love of contest, which is provided for not only by contest with others, but by the constant contest of the worker with his own previous records. When he does exceed these records he utilizes powers which it is for his good physically, as well as otherwise, to utilize.
