Calculator of global index of human cellular ageing

摘要

The calculator allows entry of data and can display the results of the computation performed on the entered data. The user enters data in response to a series of questions. The calculator has keys to select questions and to enter responses. Each key carries symbols appropriate to a question. The acceptance of values and their processing is performed by a microcontroller, which also drives a display formed by multiple seven segment displays. The questions ask information on consumption of animal and vegetable fats, sugars, alcohol, tobacco; exposure to ultraviolet radiation, work hazards; locomotion and memory difficulties; stress and fatigue; chronic illnesses; height and weight; visible signs of ageing. Questions are also asked on positive lifestyle factors.
