Body hacking

Body hacking is the application of the hacker ethic (often in combination with a high risk tolerance) in pursuit of enhancement or change to the body's functions through technological means, such as do-it-yourself cybernetic devices or by introducing biochemicals.

Grinders are a self-identified community of body hackers. Many grinders identify with the biopunk movement, open-source transhumanism, and techno-progressivism. The Grinder movement is strongly associated with the body modification movement and practices actual implantation of cybernetic devices in organic bodies as a method of working towards transhumanism. This includes designing and installing do-it-yourself body enhancements, such as magnetic implants. Biohacking emerged in a growing trend of non-institutional science and technology development.

"Biohacking" can also refer to managing one's own biology using a combination of medical, nutritional, and electronic techniques. This may include the use of nootropics, nontoxic substances, and/or cybernetic devices for recording biometric data (as in the quantified self movement).
