HOW LONG DO YOU WANT TO LIVE? Some People Are Satisfied To Live Until They Cease Being Fit And Agile, Regardless Of What Age They Attain. Others want to live for as long as they can for they are afraid of dying, so they will pay whatever they can to get younger.

If you were given one billion seconds to live from the day you become cognizant of personal responsibility, you would probably live somewhere between 106-117 years of age.  If you were also given $1 to spend every for every second of your existence, how would you see yourself spending it? 

In total you are looking at the ability to possibly spending the equivalent of some $4 billion, depending on how whether you reached 117 years of age. Bryan Johnson, for example, when around 40 years old, had a mere $300 million to spend, and he has chosen to seek the elixir of youth, so he doesn't grow old. Even then it is doubtful that he is spending $1 a second, and probably nothing near $100k a day. For if he were to spend $100k a day, he would need more than $4 billion in the even he were to live 120 years from now. Although, in Bryan Johnson's case, investments may be able to extend the shelf life of his nest egg. Besides, he is probably spending only around $10,000 a week on living expenses. Not enough to create hole in his nest. In fact, his income from investments probably would be sustaining him and his original $300 million, but that is only an assumption. A different story emerges according to the man himself, for he has already blown $100 million, one third of his goodies.

Here is the quick breakdown on Bryan Johnson's net work and financials, according to Moneywise.

Numbers from Bryan Johnson’s Moneywise Episode

     • $20–$30 million into Blueprint (longevity-focused nutrition and lifestyle business)

     • Adventure experiences: dog sledding in the Arctic, visiting an active volcano in Iceland
   • Future Liquidity Events: Several startup investments are expected to IPO or be acquired soon

   Building Wealth with Purpose

   At 21, Bryan decided he wanted to "change the course of humanity." This wasn't just ambitious dreaming—it was strategic planning. He calculated exactly what he'd need:

   • $7 million baseline to buy freedom and time (calculated in 2002)
   • He made different tiers of capital needed: $50M, $250M, $1B, and several billion
   • Each tier would unlock different possibilities for impact
   • Ultimate goal: create something that would matter in the 25th century

   "I bootstrapped Braintree, so for the first 4 or 5 years I took no outside capital," Bryan explains. "By year four we were around like 4 to 6 million thereabouts. But we were growing so fast and we had some of the fastest growing companies in the world as customers."

   Strategic Investment After Exit

   After selling Braintree for $300 million, Bryan deployed his capital:

   • Created a $100 million venture fund focused on deep tech
   • Invested $64 million in Kernel, a brain interface company
   • Maintained surprisingly modest personal spending of $10-20k monthly
   • Kept his housing costs low, renting a $5,000/month home
   • Only major luxury purchase: a private jet (sold during Covid)

   The Mission Over Money

   Bryan's financial decisions are driven by his mission. He estimates he could have turned his exit money into $10 billion through conventional business ventures, but chose not to because "from the 25th century perspective, who cares?"

   His current focus and capital allocation:

   • Blueprint, his ecommerce and media company: $20-30 million invested in health optimization
   • Don't Die: Building a global movement
   • 60-70% of remaining wealth in illiquid investments, mostly startup investments.
   • Current estimated net worth: "a couple hundred million"

So Johnson is not spending $100,000 a day. Actually, even over 100 years such a spend would amount to an astronomical total of $3.65 billion., a very difficult thing to do.

Here are some ways someone could theoretically spend that amount of money:

1. Luxury Living:

   • Renting or purchasing multiple luxury homes in various locations around the world.
   • Hiring personal chefs, trainers, and staff to maintain a lavish lifestyle.

2. Travel:

   • Frequent first-class travel around the world, staying in five-star hotels.
   • Chartering private jets and yachts for vacations.

3. Collecting:

   • Acquiring high-value art, antiques, or collectibles.
   • Investing in rare cars, jewelry, or other luxury items.

4. Business Ventures:

   • Investing in startups or businesses, potentially funding multiple projects simultaneously.
   • Buying and operating multiple businesses or franchises.

5. Entertainment:

   • Hosting extravagant parties, events, or concerts.
   • Funding film productions or other large-scale entertainment projects.

6. Health and Wellness:

   • Accessing top-tier medical care, wellness retreats, and personal trainers.
   • Investing in cutting-edge health technologies or treatments.

7. Education:

   • Paying for private education for multiple children or family members.
   • Funding educational institutions or programs.

8. Gambling:

   • Spending large amounts in casinos or on high-stakes games.

9. Miscellaneous:

• Purchasing luxury goods, fashion, and accessories.
• Engaging in hobbies that require significant financial investment, such as flying lessons or extreme sports.
10. To be honest, while it may seem extravagant, it is theoretically possible to spend that amount of money consistently over a long period. However, it would require careful planning.

11. A degenerate gambler would be able to plough through that much money living in the casinos of Las Vegas, Macau or Monaco, until thrown out penniless.

12. A philanthropist would be able to donate that much money t

    o various charities, foundations, or causes. Funding scholarships, research, or community projects.
