Can you build a personalized 24/7 Health Coach with @Claude in a day?

Yes! I connected wearables, blood biomarker data and DNA. And the results were incredible.

See the post below for detailed break down on how you can do the same.

@Finnair how convenient that you decided to cancel our HEL-LAX flight and not offer an alternative flight.

You expect us to book a one way flight at double the price?

Is this just to recoop the increase cost of petrol?

@paulg Increase salaries to $500,000 a year. Set term limits. Get competent younger people to run for office. And lower the threshold of pribery.

@fatcharlie95435 @paulg Nvidia has made multiple billionaires of people who work there. Also 50% of the 30,000 employees are worth more than $25M

@Jason I'm in.

@SethSHowes This is great! What’s the best place to purchase full sequencing to be uploaded for LLM analysis? I have old files but those are from old illumina arrays.

[Ari Tulla @umbar]

@MariaDavidson Interesting data. One valuable data point is CA GDP growth of 65%

2015: $2.5T
2025: $4.1T

@zalzally @bryan_johnson @eightsleep Huh, I don’t fit the graph. I must be a vampire.

[Ari Tulla @umbar]

@mlevchin It was spectacular.

[Ari Tulla @umbar]

@cwhogg +1 great idea!

[Ari Tulla @umbar]

I spent $1,000+ testing 5 blood biomarker services from @function @superpower @ouraring @UltrahumanHQ, and @WHOOP

Then I asked all 5 the same question: "My ApoB is elevated. What should I do about it?"

The results were revealing…

Today @redbull performed a really cool stun at Pacific Heights San Francisco. A Paris Dakar style vehicle jumped over Redbull F1 car using the SF steep hills as jump. Can’t wait for the footage.

@parkjames Great idea, much needed!

This is what building companies is all about. Well said @hnshah

[Hiten Shah @hnshah]

Most people have no idea what it actually takes to be a founder. They talk about vision, grit, or passion. Those words are props.

What you really sign up for is a life where every decision feels like it costs something real. You will spend years being misunderstood. By your team, your family, even the people you hire to help you. You will fail in public and still need to keep the energy up in private. Every founder lives with the weight of knowing that you can do everything right and still get crushed by luck, timing, or somebody else’s mistake.

Founders aren’t braver than anyone else. They just get used to uncertainty, then stop waiting for clarity. Most of your wins won’t feel like wins at all. The first revenue will be too small. The first team will outgrow you or leave. The first product that feels right will barely matter to the market. You will doubt yourself in private, sometimes every week. The founders who last figure out how to keep moving while the ground shifts underneath them.

Most outsiders want the founder badge but none of the scars. They want the upside, not the drag. The hardest part is sticking around after every plan gets blown up and you have to rebuild with less optimism and more scar tissue. What makes it work isn’t relentless hustle or some mythical trait. It’s learning to make peace with constant discomfort, and then making decisions anyway.

If you need constant reassurance, you’ll give up before the real work begins. If you want everyone to like you, you’ll never make the calls that matter. If you can’t handle months where nothing feels certain, this life will eat you alive.

But if you can hold your own in chaos, get better at being wrong, and still want to show up and try again, you just might have a shot at building something that matters.

That’s what it actually takes. And nobody cares until you make it work.
