Abstract: A health potential study and summary makes use of a multiple-page, relatively comprehensive, questionnaire for the individual, an analysis of answers to the questionnaire in readable summary form and an abbreviated life-style resume of the analysis coupled with a visually graphic portrayal of health potential on a graduated scale. The questionnaire is divided into different categories of health affecting subjects arranged so that answers in the form of yes, no, unanswered, or degree rated against a specified rate scale, are placed in a score box adjacent the question. The questionnaire includes an actual food intake diary for a specified period of days and an exercise report. The analysis and appropriate comments are presented in printed form for the respective categories in a manner comparing ideal conditions against actual conditions of the individual where prevailing conditions are picked from the score boxes and commentary and recommendations selected from a data bank according to score.
