The DISC method is a psychological assessment tool created by William Moulton Marston in the 1920s. It is designed to help individuals understand their behavior and emotions and how they affect their interactions with others.

Participants take a self-assessment questionnaire to determine the degree to which they exhibit traits of four behavioral styles: Dominant, Influential, Steady, and Conscientious.

The DISC method is commonly used by:

- Business teams to improve communication and dynamics.

- Managers and leaders to understand leadership styles.

- Individuals for personal development, enhancing self-awareness and interpersonal relationships.

After taking the DISC test, participants learn about:

- Their primary behavioral style.

- How they interact with others and the environment.

- Their strengths and areas for improvement.

- How to leverage their natural traits in both personal and professional settings.

Biohacking is the practice of using science, technology, and self-experimentation to optimize one's physical and mental performance. It includes lifestyle changes, such as nutrition and supplements, aimed at improving health, well-being, and longevity.

HRV refers to the variation in time between each heartbeat. It is a powerful indicator of how well the body can adapt to stress and recover from exertion. A higher HRV indicates resilience, while a lower HRV may signal stress or fatigue.

HRV is easily measured using wearable devices that track the variation in heart rate. These devices provide continuous insights into how the body is responding to daily challenges and do not require invasive sensors.

HRV is crucial for:

- Physical and mental performance

- Stress management

- Optimizing performance and overall wellness.

HRV can help identify stress response patterns and guide lifestyle adjustments. It provides valuable data to understand how the body reacts to stress and how it recovers, supporting better stress management strategies.

The Self-Coherence Method is based on biological data acquisition and lifestyle evaluations. It helps assess a person’s ability to balance and adapt to environmental challenges, promoting vitality and long-term well-being, rather than focusing on curing disease.

The Ikigai method originates from Japan, particularly the island of Okinawa. It is a concept that embodies the idea of living with purpose, often referred to as "a reason for being." Ikigai represents the convergence of passion, mission, profession, and vocation, helping individuals align all aspects of their life for greater fulfillment.

The Ikigai method helps individuals find purpose by evaluating four intersecting factors: what you love (Passion), what you're good at (Profession), what the world needs (Mission), and what you can be paid for (Vocation). Through introspective exercises and questions, individuals assess their life to see where these elements align, leading to greater clarity and purpose.

While the Ikigai method is more of a philosophical framework than a scientifically tested tool, research has shown that individuals with a sense of purpose—similar to what Ikigai promotes—tend to experience higher life satisfaction and longevity. However, the specific method itself may not have robust scientific validation.
