This is one of those rare times where a rhetorical question from a link-bait title is definitely "Yes"!

The author has a great anecdote about the work that is being done to combat rheumatoid-arthritis, however the story preys on our own hubris to believe that our bodies are not made up of very simple parts that have little knowledge of ourselves, rather a fairly strict set of inputs/outputs. So of course if you can manipulate the inputs, then you can achieve your desired outputs.

The true beauty of medical hacks is that the basal inputs and outputs of each individual component is relatively unknown!
