Imaging how your weight has changed over 10 years, it might response how your life has changed. The human body records something which might be reflected on the weight changes. The idea of the project is collecting a person's weight change to look back on the passing life.
The scale makes a mark without any statistical number every time when you using it. After a while, then you can read the data that the scale has made, then you can see how it changes in a graphic way. At the same time, it could record some specific events. For example, when people go travel with flight, a scale might be used for weighing luggages at home. Therefore, the data on the scale might suddenly climb in an unusual way. That specific data could easily point out some particular things have happened.
