Biohacking is a term used to describe do-it-yourself biology, which involves people making incremental changes to their bodies, diet, and lifestyle to improve their health and well-being. Biohacking is a citizen or do-it-yourself biology movement that emphasizes the connection to hacker culture and the hacker ethic. Biohacking is founded on the idea that the bodys total genetic expression can be mapped out and optimized by testing. Biohacking can be done in various ways, including:

• Diet and Lifestyle Changes: Many biohackers make small, incremental changes to their diet and lifestyle to make small improvements in their health.

• Technology-Based Biohacking: This involves using technology like smartwatches and Fitbits to track physiological changes and blood biomarkers that reflect physical fitness, disease risk, and longevity.

• Nootropics: This is a popular form of biohacking that involves using substances called nootropics, or "smart drugs," to improve cognitive function.

• DIY Biology: This is a type of biohacking spearheaded by people with education and experience in scientific fields. DIY bio involves conducting structured experiments on oneself outside of a controlled experimental environment, like labs or medical offices.

• Grinder: This is a biohacking subculture that seeks to become "cyborgs" by optimizing their bodies with a combination of gadgets, chemical injections, implants, and anything else they can put into their body to make it work the way they want it to.

Biohacking can be controversial, and some methodologies border on the unsafe or even illegal. However, biohacking can also be a way for people to take control of their health and explore new and unusual ideas.
