Exploring Your Health in 30 Days

My friends,

As some of you know, I've dealt with some health challenges over the past couple of years. One of the ways I've coped -- and learned a tremendous amount -- has been by talking with a couple of the leading AI models about my health and what I can do to become stronger and healthier.

Along the way, I realized something: these conversations weren't just helpful for me. They could be helpful for any of us. So I created this 30-day set of questions for anyone who wants to understand their body better, strengthen their metabolism, and move toward becoming the healthiest version of themselves.

If you take just one question a day, ask it to your favorite AI, have a real back-and-forth conversation, and take a little time to think about what you learned, I believe the results could be genuinely life-changing.

I'm so grateful for your prayers and good wishes toward me. You inspire me! I want to continue exploring the world and sharing what I learn along the way with you. These 30 days of healthful prompts are meant to be part of my effort to pay back the generosity and kindness that you have shown to me.

Photo note: I took this picture at the Vatican on a warm afternoon, standing beside a fountain that caught the sunlight just right. Something about the water rising and falling in a steady rhythm reminded me that our bodies work the same way -- cycles of effort and rest, motion and renewal, challenge and repair. In the middle of a difficult season, this simple scene brought me a sense of peace and direction. It felt like an invitation to keep exploring, to keep learning, and to take better care of the body that carries me through the world. I hope these 30 days of questions do the same for you.

So here you go -- 30 questions for 30 days of growth, insight, and better health.

Much love,
BR

P.S. QUICK TIP FOR BEST RESULTS
I've found these conversations go much deeper if you set the stage first. Before asking Question 1, copy and paste this sentence to help the AI explain things clearly:

"Act as an expert health educator who specializes in explaining complex biology to smart, motivated adults. I want to understand the science deep down, but explained in plain English. Please use clear real-world analogies (like how a car engine or a bank account works) and use tables or timelines to make the information easy to digest."

P.P.S. If you find these helpful or have any feedback for me on how to improve them, I sure would appreciate hearing back from you.

Also, I think handling vehicles this way will set the stage for real estate ownership records/deeds, which is one of the most glacial information markets on the planet.
Can't wait for that to get tuned up!
Let's go digital!
🚀🚀🚀

[Brian Reithel @BR_zone]

Paper titles still underpin one of the largest asset markets in America.

You only notice the system when you sell a car, clear a lien, or move ownership across a state line.

That layer is starting to be rebuilt.

CHAMP Titles is putting digital titling rails under state DMVs, dealers, lenders, insurers, and fleets. California has digitized 42 million vehicle titles on a DMV-managed Avalanche network.

This is not “cars as NFTs.”

It is the pink slip becoming a state-backed digital credential: verifiable, harder to launder or alter, and eventually transferable without a week of mail.

The real breakthrough is not one state going digital. It is states recognizing one another’s records, so an out-of-state sale feels closer to sending money than shipping paperwork.

When that happens, the U.S. vehicle market finally gets an ownership layer that matches how cars are actually bought, financed, and sold.

Congratulations Eric and team! This is what modern American innovation looks like. 👏

[Eric Olszewski 🇺🇸 @EricOlsz]

This week, @ActinideInc became the first startup in history to enrich uranium, producing HALEU, the fuel for next-gen and small modular reactors.

We did it using Endurance, a particle accelerator that we designed and built in Texas.

Endurance usually produces enriched Yb-176, a precursor for cancer therapies worth roughly $30,000 per gram.

After a bulk Yb-176 delivery on July 30, we reconfigured Endurance for uranium.

TL;DR of my new article: every Grok Bot hack I know.

Grok Bot is two weeks old. It already runs my inbox, my research, my meeting notes, my kids' calendar, my grocery cart, and as of this morning it makes my phone calls in Portuguese.

📝 Install Compound Engineering in your bot and make it plan first (@kieranklaassen + @trevin). Force a plan, get better work
📬 Give your bot its own inbox on @agentmail (@adisingh). Not your Gmail, or one bot's mistake flags your whole domain
☎️ Give it a @twilio number and it makes the call. Mine switches to Portuguese mid-call (@martindonadieu showed the shape)
🔎 Turn a bot into @slashlast30days, then cron it weekly on your business, your competitors, yourself
🚪 One front door that delegates. @mattshumer_ pointed a Chief of Staff at two bots expecting it to fall apart. It worked out of the box
🧭 Hire a Bot Advisor whose only job is building and tightening your other bots (https://t.co/Tdprqqq3gE, inspired by @petergyang)
💼 Permanent named roles, then fire the ones that don't work. @HouseHackerJon automated work-order intake in 4 hours and fired his first bot
🧱 Write the instructions in three layers: base, role, current focus
🤫 Silence is the hack. Ping me ONLY on a real hit (@johnviklund, @PrajwalTomar_)
📸 Screenshot anything and text it to your bot. Never retype what's already on the screen
🍪 Agent Cookie syncs your Chrome session over Tailscale so it never gets logged out. New machine, new address, a week untouched, Instacart still worked first try
🖨️ Printing Press CLIs inside the bot (@ppressdev): Instacart, ESPN, flights, tickets
👀 Peekaboo, @steipete's Mac automation tool, so it can see AND click your native Mac apps, not only the cloud browser (via @benln)
💻 You can log into Claude Code on your bot's own computer (@Austen)
🥣 GranolaBoy: every meeting I've ever had, one question away (@meetgranola)
⏺️ Teach by recording, and respect the 10 minute cap nobody mentions (@DillonLoomis)
🗂️ Files are the memory bus between bots. Bots are NOT a security boundary. The docs say that twice
🛑 Draft-then-approve anything that sends. @darian314's bot paid its own monthly fee hunting down refunds
📚 Steal the lists: @ericzakariasson's 100, @benln's internal one, @milesdeutscher's 25, @petergyang's tutorial. Plus @kunchenguid's Grok Ship
📱 Run it from your phone, and talk to it
💸 The honest part: the price moved to $60 but the meter didn't, unsupervised crews multiplied their own errors 17x, and most of your bots don't own an outcome. Count them.

It has become blindingly obvious that SpaceXAI has all the leverage to be the leader in AI.

OpenAI is run by a clown who converted a non-profit into a for-profit and everyone's leaving.

Anthropic went from not existing 4 years ago to getting a 2T valuation or something? but they have no infrastructure and have to go borrow and lease computers to train their models.

SpaceXAI is part of SpaceX, one of the most elite groups of physical world engineers and atom movers in all of history. They're also big homies with Tesla, another team of some of the greatest physical world engineers and atom movers in all of history. Tesla also happens to have the best real-world AI team and the best real-world AI consumer product on the market.

Together, they can pipe intelligence into physical products and build an ecosystem for AI while their competitors have to go around asking people to let them borrow a computer to train their expensive models on.

I can't believe the moment we've come to today. Total underdog story from xAI, but here we are. They have a great model, just released a viral AI product, are about to fuck your face off with Grok 4.7, and they've got all the momentum in the world.

Fuckin' Elon, man. lmao.

@grok How does that vein hit rate compare with human nurses?

[Brian Reithel @BR_zone]

There was one day when I was in the hospital back in 2023 that I got stuck 14 times. The vast majority of those were attempts where the nurse-trainees were not successful. Bots now, please!

(I actually told the nurses back then to send in the "ninja", the best nurse at poking blood vessels in the hospital. )

[Interesting Engineering @IntEngineering]

The FDA has authorised Aletta, a device from Dutch company Vitestro that finds a vein, inserts the needle and fills the tubes without a human touching the patient. It uses near infrared light to spot the vein, then ultrasound and Doppler to measure its depth and confirm it is not an artery, before an arm places the needle with sub millimetre precision. In a 1,633 patient trial published in Clinical Chemistry, it hit the vein on the first attempt 94.5% of the time.

@BackWoodsGuy63 Not just accounting jobs, but I loved the deeper business insight that they solved their customers' problem rather than just sold their customers yet another whiz bang gadget. People will pay to have their problems solved all day long, if those problems are important enough. ✔️

[Brian Reithel @BR_zone]

Bingo! 🎯👏

[Joanathan McIntosh @joanathanlmc]

We did $100k in revenue after realizing that our customers hate software.

Our first product was an AI accounting tool for CFOs. I did 35 sales calls and got $0.

So we switched to being a service.

The pitch became: "We're an outsourced accounting firm that's faster/cheaper with AI"

Then our calls started to convert.

As founders, we naturally obsess over features and tech because that’s what we do.

But REAL customers don't care. They only want their problem solved (bonus points if they don't have to use the tool) in a fast, simple way.

Just sell the outcome.

Milestone on the match to make consciousness multi-planetary. Well done Florida launch team! 👏🚀🚀🚀

[Kiko Dontchev @TurkeyBeaver]

This morning’s @SpaceX mission from pad 40 was the last planned Falcon 9 Starlink launch from Florida (and it launched on the fleet leading booster!!), marking the end of an era for these launches on the East Coast. From here on, Starlink missions out of Florida will fly on Starship. The West Coast team will continue regularly launching Starlink from Vandenberg.

Super proud of this incredible team. You’ve made Falcon 9 the most reliable launch vehicle in history. You also helped build the largest low-Earth orbit satellite constellation providing connectivity to millions around the world, and you’ve set the foundation for what’s next.

In the last seven years, Falcon has flown ~260 Starlink missions from the Cape… can’t wait until we launch that and many more with Starship!

More data than open-source AI is taking share from OpenAI and Anthropic. Open source has gone from 28% token share to 62% token share @vercel over the last 2 months. Chart from @rauchg

Super impressive given that the sum of OpenAI and Anthropic accelerated in July. So net token/AI infra demand accelerated even more than the acceleration we saw at the frontier. And suspect Grok growing even faster than open-source and we saw some of this in the @tryramp data.

Open-source AI taking share is positive for AI infrastructure demand as it lowers margins at the model layer and an open-source token costs just as much compute to produce as a frontier token. Nothing about open-source AI inference is “free.”

Most likely end state IMO is that closed, frontier tokens are 60-90% of economic value but only 15 to 25% of tokens.

This is the sort of thing that makes one stop and wonder... It couldn't all be that rigged, could it? 😎

[Dividendology @dividendology]

This image has gone mega-viral over the last 24 hours.

If you bought Micron every day at market close and sold at market open, your return would be 138,330,342%.

If you bought Micron every day at market open and sold at market close, your return would be -99.2%.

I went down a rabbit hole to see if I could discover as to why this is.

An earlier historical dataset from researcher Bruce Knuteson produced similarly extreme results for a number of individual stocks:

• $MU: +16.2 million% overnight / -99.95% intraday
• $HOLX: +15.9 million% / -99.98%
• $NVR: +3.6 million% / -98%
• $JBHT: +3.0 million% / -99.8%
• $MGM: +2.6 million% / -99.96%
• $NVDA: +221,715% / -51%

Obviously, the exact numbers depend heavily on the period examined, but the pattern itself has been repeatedly documented.

Research published in the Journal of Investment Management found that the phenomenon is particularly strong among high-attention stocks popular with retail investors, including names such as:

$NVDA
$TSLA
$AMD
$MSTR

But here's what I didn't expect:

Over the 30-year period examined in subsequent research, $1 invested in only during regular trading hours grew to roughly $1.20.

The same $1 invested only overnight grew to approximately $17.27.

So why does this happen?

There are several theories.

One of the most interesting involves when investors actually place orders.

Retail investors often place orders during post or pre market hours.

Those orders accumulate while the market is closed and are executed around the opening auction.

That creates persistent buying pressure near the open, especially in popular, high-attention stocks.

There are a few other possible explanations as well:

• Earnings and major corporate news frequently arrive outside regular trading hours.

• Investors require compensation for accepting overnight gap risk when they cannot immediately exit a position.

• Institutional investors face different leverage, short-selling and financing constraints overnight.

• Liquidity and price impact behave differently around the opening and closing auctions.

• High-beta stocks appear to experience a particularly large day/night return split.

Researchers still disagrees on how much each explanation contributes.

Tesla’s 2026 milestone list is absolutely insane
And we are still in August

January 8 — Giga Shanghai produced its 5 millionth drive unit
February 17 — First Cybercab rolled off the production line at Giga Texas
April 3 — Tesla reached 80,000 Supercharger stalls globally
June 30 — Model Y crossed 5 million global sales
July 2 — Tesla Energy deployed 13.5 GWh of storage in Q2 alone
July 30 — Tesla produced its 10 millionth vehicle globally
Early August — FSD (Supervised) crossed 13 billion cumulative miles
August 18 — Giga Shanghai produced its 6 millionth battery pack
August 21 — FSD (Supervised) crossed 50 million km driven in South Korea

Tesla is scaling across every layer of the future of transportation, autonomy and energy at the same time

And 2026 still has more than four months left

Little Mirrors 14 -- Before You Judge

We judge quickly.

A sentence.
A headline.
A photograph.
A political label.
...
Sometimes that's all it takes.

There are ancient reasons for it. Our brains evolved to make fast judgments from incomplete information. For distant ancestors, deciding quickly whether something was safe or dangerous, friend or foe, could mean survival.

That ancient machinery is still with us.

The problem is that it now operates in a world very different from the one in which it evolved: social media, political tribes, twenty-four-hour news, and encounters with people whose lives we may know almost nothing about.

And once we decide who someone is, the mind gets remarkably good at finding evidence that confirms that judgment.

But every person has a story we have not heard.

Experiences we haven't lived.
Fears we don't understand.
Reasons that might make more sense if we knew what came before.

Understanding doesn't require agreement.
Compassion doesn't require approval.

It simply asks us to become curious enough to wonder:

"What might I understand differently if I knew the rest of the story?"

Maybe judgment needs a little less certainty
and a little more imagination.

Maybe our ancient instincts need a moment to pause, so that our reflective minds have time to catch up.

Photo note: I took this photo in 2019 in Jerusalem. This elderly woman was walking along a busy street with a cardboard box tethered to a pink cord behind her. Looking at her, I could already feel my mind beginning to imagine her story.

I did not know who she was, what was in the box, where she was going, or what had brought her to that particular moment.

And yet a photograph like this invites the mind to fill in the blanks almost immediately.

There was a story here. Probably a long and complicated one.

I simply did not know it.

Maybe that's worth remembering whenever we think we understand another person from the small piece of their life we happen to see.
