Exam work

My exam question I am looking at is Personal Possessions. I thought about maybe doing documentary photography of documenting somebodies life. Starting with present photography of documenting somebodies life here and now, taking pictures of what people leave behind so it's not staged - it's general life. I would then like to move on to present and past so using people (a bit of human form) showing past and present, then past photography so memories of something in paticular to remember what their life was like.. I could try by using memory boxes, or types of fashion/music to resemble older times, or even a past hobby.
