Reading the articles of last week got me thinking of a machine I’ve created in my mind which will significantly improve and facilitate human lives. It all started with my annoyance at how I never know how many calories I’m taking in each day and my curiosity of how much I’m burning, compared to my intake. So I imagined a machine, a small flat, paper-thin screen attached to a human body that scans and calculates all the processes going on. It will not only calculate amount of calories, fat, sugars, vitamins, etc, but will be adjusted to a person’s individual rhythms and will suggest improvements based on the diet (for example, it can identify deficiency of vitamin A and suggest you eat more foods containing that vitamin). In addition to that, it might suggest different types of physical activity that are suitable for the body type and any body conditions the individual might have (for example, if he/she has a sprained ankle, it will only pick out work-outs that do not strain it additionally). Further on, it will be able to scan the whole body to identify health problems (anywhere from a unheathly BMI to heart conditions, liver damage or cancerous cells). There will be no more need for x-rays or blood tests; no visits to the doctor to diagnose, only to treat (by, for example, showing a health report compiled by the machine). No more weighing scales, body thermometers, nutrition information, blood pressure or sugar levels gadgets. This baby will have it all. Some might argue that such a machine forces people to know how many calories they eat and thus takes some of the simple pleasure of eating away. Therefore, there will be options to shut this specific function, or others, off. The idea of being able to diagnose a potential tumor or a heart attack right away can save millions of lives. The implications are countless.
I envision such a device to work in the following way: millions of robot-submarines (already invented), as small as (or smaller) than red blood cells will travel through the body, communicate with each other and send signals to the main screen, which will display the outcomes of the surveys they make. It will then make connections between the different outcomes so as to come to a general conclusion. In my opinion, this is not a wishful-thinking machine since some of the components I discuss are already in existence. The next step would be to just put it all together.
