When Your Epigenetic Age Says One Thing, But Your Lungs Say Another: My Wake-Up Call
How comprehensive clinical testing revealed the truth behind alarming proxy measurements—and why biohackers need both data streams
Warning: This is a LONG article with a ton of info and actionable items. I am sharing my personal lab results as well as I am super open to where I stand when it comes to longevity & biohacking.
THE ALARMING DISCOVERY
In July 2025, my TruDiagnostic Advanced Age report delivered a gut punch: my FEV1 (Forced Expiratory Volume) percentile ranked at 11.9%—meaning my lung function appeared worse than 88% of women my age. As someone who skis to the South Pole, climbs 14,000-foot peaks, and dives 120+ feet underwater 100+ times annually, this made zero physiological sense.
But here’s where precision medicine gets interesting: that measurement wasn’t from actual spirometry. It was an epigenetic proxy—a DNA methylation pattern predicting lung function based on population data. And proxies, I was about to learn, don’t always tell the complete story.
