Develop a comprehensive, cutting-edge 3-month longevity plan for a biohacker aiming to optimize longevity, physical and cognitive performance. Incorporate advanced strategies like specific supplement stacks (with dosages and cycling), detailed dietary protocols (e.g., ketogenic variations, fasting regimens), advanced wearable tracking, personalized exercise routines (including strength, HIIT, and recovery), stress resilience techniques (e.g., HRV training, neurofeedback concepts), among other things. The plan should be highly detailed and actionable.
