🧪 WHO AM I?
Hi Friends - I am the world’s most measured human. At 46, my cardiovascular fitness ranks in the top 1.5% of 18 year olds; I celebrate my birthday every 19 months because we’ve dramatically slowed my speed of aging, and in 2023 I achieved the world’s best recorded sleep score, 8 months of 100% perfect sleep.
This is remarkable because previously, my health was in a pretty bad place.
In 2020, I started Project Blueprint to help you achieve similar results. I share everything I do and learn for free, so you can access the best health science available.
Project Blueprint and Don’t Die celebrate that we, humanity, are evolving into something new. Join me on this journey.

Mindsip insights from this episode:
Prioritize eight hours of sleep as a heroic act
Contrary to the cultural idea that sleep deprivation is brave, getting eight hours of sleep is a heroic act for yourself and your loved ones.
Adapt to sleep challenges when traveling from optimized environments
Becoming accustomed to a highly optimized home sleep environment, like a temperature-controlled mattress, can make sleeping while traveling more challenging.
Set final mealtime at 11:30 AM for optimal digestion
After hundreds of experiments, the speaker found his ideal time for his final meal was 11:30 AM to ensure digestion was complete before his 8:30 PM bedtime.
Maintain resting heart rate between 46-50 bpm for optimal sleep quality
A resting heart rate between 46-50 bpm was the best predictor of a perfect night's sleep, while a higher rate guaranteed about 30% less sleep quality.
Adopt a nighttime persona to disconnect from work
To mentally separate from the workday, the speaker adopts a "Nighttime Brian" persona one hour before bed, who is not responsible for work-related thoughts.
Eliminate caffeine for stable mood
The speaker quit caffeine and alcohol entirely not just for sleep, but primarily because they created mood swings, and he now feels very stable all day.
Utilize temperature-controlled mattress for optimal sleep
The speaker uses an Eight Sleep mattress, programming it to cool from 73°F to 69°F for deep sleep and then warm back up for waking.
