Close-loop body

A combination of new emerging fields may enable the opportunity to "close-the-loop" on our own body. The first is "personalized medicine", which promises to tailor each person the specific medication she requires based on a full analysis of her genome, epigenome, proteome and other –omes. The basic tenet of this new and exciting field is that by knowing each person's genetic and protein make-up, we can better design a medicinal treatment for each illness.

The second field is "self-monitoring", which at its extreme results in taking a blood sample each day and completely analyzing its cellular and molecular content. In an ambitious self-experiment, a researcher (forgot his name) did that on himself for several weeks. One finding, for example, was that these measurements indicated a flu he had much earlier than any other symptom he felt. Furthermore, the decrease of prices for such tests, following Moore's law, can results in each person being able to administer such measurements on a daily basis.

Finally, the field of "specialized consumption" (I made this name up) claims that one can drink a single fluid that contains the entire bodily requirements of the human body. No other food sources are needed to survive and thrive. These liquids, while being probably not that tasty and expensive, enable a much tighter control over what goes into our body.

Combining these three fields I suggest an experiment to try and close-the-loop on a human body. By this I mean that a person consumes only the aforementioned liquid, thus fully controlling the input to the body, while at the same time having a complete monitoring of the body functions, via the aforementioned measurements. Closing-the-loop here means changing the contents of the input liquid based on the results of the measurements in an attempt to reach some kind of equilibrium.

Obviously this is not an easy experiment, but it is not dangerous or harmful in any way. The results would also obviously be different for each person, but by closing-the-loop one may attempt to "conform" the body function.

If this experiment works, it means a whole new level of human existence, in the sense that one can have a full, and rather straight-forward control over one's own bodily functions.
