"Computers are hardware. Apps are software. Humans are wetware." The term 'hacker' is familiar to most of us this age where almost all of us are dependent on computing devices for information. On the other hand, 'biohacker' is uncommon. Biohacking is where a hacker experiments and modifies the human body by implanting or connecting devices to specific human body parts to enhance human experience by adding additional senses and/or functions.
