The art of adding unnatural sensory input, sensitivity, and other physical features and abilities not normally possible by the human mind or body. Biohacking requires an intimate understanding of the science behind not only the “features” you are wishing to add or enhance, but also any reagents or components required, their interaction of the human body, and the medical skill required to successfully and safely integrate them. One who performs biohacking is referred to as a grinder within its circles.
