Here is an ""attempt to synthesize adolescent experience"", to give an interpretation of general youthful problems in terms of life. Very elementary, closer to the self-help type of book. First a talk on anatomy and physiology, then on personality and handicaps leading to average behaviour manifestations, finally on proper use of scientific knowledge (syphilis, etc.). Basic problems of family adjustment, sexual adjustment, job adjustment and marital adjustment. The manner is straightforward, no talking down to the adolescent, but from the adult viewpoint the material covered seems to have been done before and to be reminiscent of twice told tales. Hasn't it been done just about this way? There seems nothing conclusively different in approach or handling. Perhaps there is need for another. If so this is conservative and adequate.
