Calorie Iintake Reader (C.I.R.)
We all know of instruments that can measure the calories you burn out, but what if an instrument was invented which would calculate the calories you're taking in through all that you eat and drink through out the day. You could then decide whether you go light on dinner or just skip it! The thing to work on now is to figure out on to which part of the body should the instrument be attached and the system it would use to calculate.
