49-year-old biohacker breaks down what current anti-aging tech can and cannot fix in 2026:
Cannot reverse yet:
• Facial aging markers
• Hearing degradation
• Male pattern baldness
• Dental aging
• Brain structural changes
Verified biomarkers achieved (all clinically measured):
• Nocturnal erections: 99th percentile
• Fertility metrics: 99th percentile
• Blood glucose control: 99th percentile
• Vascular function: 99th percentile
• Muscle mass: Top 5%
• Body fat: Bottom 5%
• Bone mineral density: 99.5th percentile
• Systemic inflammation: Undetectable levels
The gap is real: You can have a metabolically 20-year-old body while your face, hair, and brain structure still show chronological age. Current longevity protocols excel at internal systems (cardiovascular, metabolic, musculoskeletal) but struggle with visible aging and neurological structure.
This is the 2026 anti-aging reality check—no one's solving facial aging or regrowing hair follicles at scale yet, but you can absolutely rebuild your internal engine to peak performance.
