About me
I'm David Siegel. I'm 66. I'm a lifelong entrepreneur. I've started over a dozen companies in consulting, tech, and crypto. You can see my products around you every day. I've written six books, given hundreds of speeches, been to 99 countries, and have been an African safari guide. I was once a candidate to be the dean of Stanford business school.
I've had one spinal fusion, four heart procedures, and a full stroke. I've broken both hips. I still have an irregular heartbeat from all the years I spent doing competitive endurance sports like running, cycling, and inline skating. I've had two knee operations, ankle reconstruction, and shoulder surgery. About once a year, I experience benign paroxysmal positional vertigo (BPPV), which I don't recommend to anyone. Today, I run, ruck, do stairs, am in the gym five days a week, teach tennis, and walk extensively.
I've had personal assistants, beautiful homes, expensive cars, concierge services, and private banking. It hasn't been that satisfying. What's satisfying is great health, peak new experiences, adventure travel, and good friends.
I became a health, fitness, and longevity coach after reading Peter Attia's book and realizing no one is getting aging right. Almost everything you read and see on aging is either standard recycled myths, or promising new drugs and treatments that sort of work on mice and haven't been shown to work on humans. The media is statistically illiterate. When you learn about "blue zones," where people live longer than most, the journalist tells you what's causing the longevity, but the truth is we have no idea what causes the longevity.
From 2016 to 2021, I went through a very long, complicated, expensive divorce. Since then, I've helped guide couples to a better, friendlier, faster, cheaper divorce that is better for kids and for their future relationship. See my divorce page to learn more.
