Biohacking refers to the practice where individuals implement lifestyle changes, experimental biology, or self-experimentation to enhance their body's natural capabilities and overall health. Often dubbed as 'DIY biology,' biohacking can range from simple dietary alterations to more extreme measures, such as the implantation of devices that monitor or manipulate body processes.

The term 'biohacker' encompasses those who engage in these practices. A notable example is the couple, Kayla Barnes-Lentz and her husband, Warren, who reportedly spend six figures annually on biohacking. They follow a stringent daily regimen with the goal of significantly extending their lifespan, aiming to live until at least 120 years old. This might include a combination of nutritional strategies, exercise routines, sleep modifications, and possibly more invasive interventions like gene editing or biometric implants.

Biohacking has grown in popularity due to its potential for making impactful changes to one's health and well-being. Advocates argue that with the correct tools and knowledge, individuals can proactively manage their own health to feel younger and potentially elongate their life. However, the practice is not without its controversies and risks, including safety concerns and ethical issues, particularly with more invasive techniques.

In an increasingly health-conscious world, biohacking presents an intriguing intersection of technology, medicine, and personal wellness strategy. While it promises much, it also raises significant debates about the physiological and ethical implications of such deep personal intervention.
