What if one of the most powerful systems in the global economy isn't the stock market or international banking—but the way the world buys oil?

In this episode of vpod.ai, Mike and Susan explore the petrodollar system and the remarkable chain of events that connected oil, the US dollar, international trade, government debt, and geopolitical power.

The story begins after World War II with the Bretton Woods system, when the US dollar became the center of global finance and could be exchanged for gold at a fixed rate of $35 per ounce.

That system eventually came under enormous pressure.

As US spending increased during the Vietnam War and the Great Society era, foreign governments began exchanging their dollars for American gold. In 1971, President Richard Nixon ended the dollar's direct convertibility into gold, creating the monetary turning point commonly known as the Nixon Shock.

Then came the 1973 oil crisis.

The disruption exposed just how dependent modern economies had become on reliable access to petroleum. Against that backdrop, the United States developed a new strategic relationship with Saudi Arabia that helped reinforce the dollar's central role in global oil trade.

This episode explores:

• How the Bretton Woods monetary system made the dollar central to global finance

• Why the United States abandoned direct dollar-to-gold convertibility in 1971

• How the 1973 oil crisis reshaped energy and economic policy

• Why oil became deeply connected to demand for US dollars

• How countries obtain and maintain dollar reserves for international trade

• What "petrodollar recycling" means and how oil revenues can flow back into US assets

• Why US Treasury securities became important to the global financial system

• How dollar-based finance can influence sanctions and international relations

• Why China, Russia, India, and other countries are exploring more trade in alternative currencies

• How BRICS fits into the broader discussion about reducing dependence on the US dollar

• Why replacing the dollar is much harder than simply choosing another currency

• How liquidity, financial infrastructure, legal systems, and network effects reinforce an established reserve currency

The conversation also examines one of the biggest long-term questions facing the petrodollar system: energy transition.

If solar power, wind energy, nuclear power, and other alternatives eventually reduce the world's dependence on oil, could the relationship between energy and the US dollar change with it?

And if it does, what could that mean for the structure of global economic power?

Listen to the full episode for a journey from Bretton Woods and the Nixon Shock to OPEC, Saudi Arabia, BRICS, alternative currencies, and the changing future of global energy.

Could something as simple as lemon water change the chemistry inside your kidneys—and even affect how quickly your blood sugar rises after a meal?

In this episode of vpod.ai, Mike and Susan explore the science of citrate, the naturally occurring compound in lemons that plays a surprisingly active role in the body. Using the image of mineral buildup inside an old electric kettle, they explain how calcium can crystallize inside the urinary tract and how citrate may interfere with that process by binding to calcium and helping keep it dissolved.

The conversation also moves from the kidneys to the mouth, where digestion begins. You’ll hear how acidity can affect salivary alpha-amylase, the enzyme responsible for beginning the breakdown of starches such as bread, rice, pasta, and potatoes.

Topics covered include:

• How citrate interacts with calcium in the urinary tract
• Why citrate levels matter in kidney stone chemistry
• Research discussed in the episode involving lemon juice and urinary citrate
• How acidic drinks can affect salivary alpha-amylase
• A study examining lemon juice, white bread, and post-meal blood sugar
• Why timing lemon water with a starch-containing meal may matter
• The difference between fresh lemon juice and some commercial lemon products
• Why a small lemon wedge may provide far less juice than amounts used in research
• How lemon peel can be used instead of discarded
• Practical precautions for protecting tooth enamel when drinking acidic beverages
• Why the episode recommends rinsing with water and waiting before brushing

The discussion also challenges several popular lemon-water claims. Rather than focusing on vitamin C, calorie counting, or the idea of “alkalizing” the blood, Mike and Susan concentrate on the specific chemical mechanisms described in the studies featured in the episode.

If you’ve ever wondered whether fresh lemon juice is meaningfully different from bottled alternatives, when lemon water might be most useful, or what citrate actually does once it enters the body, this episode breaks down the chemistry in practical, visual terms.

What if the earliest warning signs of cardiovascular disease have nothing to do with chest pain?

In this episode of vpod.ai, Mike and guest expert Susan explore several surprising physical signals that may appear as arteries narrow and blood flow becomes restricted. From predictable calf cramps while walking to rhythmic pulsing sounds in the ear, the conversation examines how the circulatory system can reveal problems long before a major cardiac event occurs.

You’ll hear how blood-flow limitations can affect different areas of the body and why seemingly unrelated symptoms may deserve a closer look.

In this episode:

• Why recurring calf pain during walking can be associated with peripheral artery disease and claudication

• How reduced blood flow may contribute to problems involving the lower back and lumbar region

• What a carotid bruit is and why a physician may listen for abnormal blood-flow sounds in the neck

• Why pulsatile tinnitus can create a heartbeat-synchronized whooshing or thumping sound

• How erectile dysfunction may sometimes appear before more obvious cardiovascular symptoms

• Why atherosclerosis can develop gradually over many years before noticeable symptoms appear

• How blood pressure, cholesterol, blood sugar, smoking history and family history fit into the bigger cardiovascular picture

• Why recognizing unusual patterns and discussing them with a healthcare professional can matter

The episode also explores the physics behind turbulent blood flow and considers a future where wearable technology and acoustic sensors could potentially help identify subtle cardiovascular changes earlier.

The central message is simple: cardiovascular disease may develop quietly, but the body can still produce signals worth paying attention to. Recognizing those patterns can create an opportunity to discuss cardiovascular risk with a qualified medical professional before a serious event occurs.

What if some of the biggest influences on your health aren’t dramatic medical events, but the ordinary things you do every day?

In this episode of vpod.ai, host Mike and guest Susan explore the hidden variables that may influence physical strength, memory, metabolic health, development, disease prevention, and cancer detection.

They start with something nearly everyone does for hours at a time: sitting. Prolonged time in a chair may reduce activation of the glutes and deep core muscles, creating problems that an intense gym session doesn’t necessarily undo. The conversation explores how isometric exercises and yoga can challenge these stabilizing muscles and why postural strength may affect more than back pain.

The episode also examines research into exercise and sleep deprivation. A study involving healthy young adults tested whether 30 minutes of moderate evening cycling could help protect memory following a severely shortened night of sleep. The findings raise fascinating questions about exercise, deep slow-wave sleep, and cognitive recovery.

Other topics include:

• Why prolonged sitting may contribute to neuromuscular deactivation

• How yoga and isometric holds challenge deep postural muscles

• What exercise may do for memory after an unavoidable short night of sleep

• Research examining soft drinks, energy drinks, coffee, and depression

• Why correlation does not necessarily establish that a beverage causes depression

• How DEHP exposure from soft plastics is being studied in relation to childhood neurodevelopment

• Why heating food in soft plastic containers may increase chemical exposure

• The difference between relative risk reduction and absolute risk reduction

• What a large statin trial in healthy adults over age 70 found about cardiovascular events

• Why patients may want absolute numbers when discussing preventive treatments

• How microRNAs and tumor markers are being investigated for pancreatic cancer detection

• The potential for blood testing to identify cancer recurrence before it appears on conventional imaging

The larger theme connects all of these studies: the body continuously responds to its environment.

From the chair you sit in and the container holding your lunch to when you exercise and how medical risks are communicated, seemingly small variables can shape much larger health decisions.

Listen to the full episode for a research-driven discussion about the everyday signals your body receives—and why questioning those signals may change the way you think about health, prevention, and longevity.

How many bodyweight squats should you be able to do for your age—and what can your squat performance tell you about your long-term mobility?

In this episode of vpod.ai, Mike and Susan explore the bodyweight squat as more than a leg exercise. From getting out of a chair to climbing stairs and lifting groceries, the same fundamental movement patterns show up throughout everyday life.

They break down age-based 30-second sit-to-stand benchmarks discussed in the episode, including:

• Ages 20–29: 26–27 reps
 • Ages 30–39: 27–38 reps
 • Ages 40–49: 24–26 reps
 • Ages 50–59: 22–23 reps
 • Ages 60–69: 18–19 reps
 • Ages 70+: 12–13 reps

But age isn't the only factor affecting performance. The conversation examines how resistance-training experience, ankle mobility, body composition, previous injuries, and medical conditions can change how many quality repetitions someone can perform.

You'll also hear a practical breakdown of squat mechanics, including why your heels should remain planted, how your knees should track with your toes, why chest and spinal position matter, and how pushing your hips back helps engage the glutes and hamstrings.

Most importantly, the episode explains why chasing a number shouldn't come at the expense of proper form. Your personal starting point and progression matter more than competing against an age-group average.

The bigger question goes beyond exercise: could maintaining the ability to squat, sit, and stand comfortably help preserve functional independence as you get older?

What happens when you no longer need to open an app to get something done?

For two decades, our digital lives have revolved around apps, subscriptions, menus, buttons, and walled gardens. But AI agents could radically change that model by working across services in the background, completing tasks without requiring users to navigate traditional interfaces.

In this episode, Mike and Susan explore the potential collapse of the traditional app economy and the rise of AI agent swarms—digital assistants capable of gathering information, analyzing data, interacting with services, and delivering results while bypassing much of the interface we use today.

The conversation explores:

• Why cheaper AI-powered software development threatens one-size-fits-all apps

• The prediction that as many as 80% of consumer apps could eventually disappear

• How AI agents could bypass traditional app interfaces and walled gardens

• Why App Store fees, advertising, subscriptions, and SaaS economics could face pressure

• The “LLM moat” problem facing startups built on top of foundation models

• Why proprietary data and deep infrastructure integrations may become critical competitive advantages

• How generic AI models can compete with specialized fitness, legal, and productivity applications

• Why real-world operational data could become one of software’s strongest defenses

• How college students are using AI to build businesses with dramatically fewer technical barriers

• The University Growth Fund model and the role students play in deploying real venture capital

• The “experience deficit” that can emerge when people rely on AI without enough real-world judgment

• Why lived experience, relationships, trust, and reputation could become increasingly valuable as technical skills are automated

The episode ultimately raises an even bigger question: if AI agents begin booking flights, ordering groceries, negotiating insurance, and choosing products on our behalf, will companies still market primarily to people—or will they start competing for the attention of our digital proxies?

The app economy was built around getting humans to click. The next economy may be built around convincing machines to act.

Tune in for a wide-ranging conversation about AI agents, the future of SaaS, software disruption, venture capital, entrepreneurship, proprietary data, human experience, and what happens when the interface itself begins to disappear.

The lights turn on. Clean water comes out of the tap. Fuel reaches the gas station. We rarely think about the hidden computer systems making these everyday conveniences possible—until something goes wrong.

In this episode of vpod.ai, Mike and Susan explore operational technology (OT), the hardware and software controlling physical infrastructure such as pipelines, water systems, factory machinery, and power networks.

As traditionally isolated OT systems become connected to IT networks, cloud services, and remote monitoring tools, efficiency improves—but so does the potential attack surface. A stolen password, unchanged factory credential, or malicious link can have consequences far beyond lost files or compromised accounts.

In this episode, discover:

•  What operational technology is and how it differs from traditional IT 
•  Why industrial systems were historically protected by air gaps 
•  How internet connectivity changed the security of critical infrastructure 
•  Why cyberattacks can create real-world physical consequences 
•  How a single compromised password can disrupt essential services 
•  Why default passwords remain a serious security weakness 
•  How AI can accelerate both cyberattacks and cybersecurity defenses 
•  Why two-factor authentication, unique passwords, and cautious clicking matter 
•  Whether making every household device “smart” is worth the additional risk 

Cybersecurity is no longer only about protecting information. When computer code can control machines, pipelines, water pressure, and other physical systems, digital security becomes closely connected to physical safety.

And as more devices come online, there’s a bigger question worth asking: How much connectivity do we actually need?

What if you could help manage post-meal blood sugar without even getting out of your chair?

In this episode of vpod.ai, Mike and Susan explore research on the soleus push-up—a simple seated calf raise that activates the soleus muscle in the lower leg. The discussion looks at why this small muscle may have an outsized effect on glucose regulation during prolonged periods of sitting.

They unpack findings discussed in the episode, including a 2025 study in which participants took three-minute movement breaks every 30 minutes and performed soleus push-ups. The conversation also examines an earlier, more intensive experiment involving sustained soleus activity following a glucose drink.

You’ll learn:

• How to perform a soleus push-up while seated
 • Why the soleus muscle can sustain low-intensity activity for long periods
 • How seated calf raises may affect post-meal glucose and insulin response
 • Why the soleus is described as the “heart of the lower extremities”
 • How muscle contractions help move blood through the lower legs
 • Why short bouts of movement can matter during prolonged sitting
 • How soleus push-ups compare with walking after a meal
 • Why seated calf raises should complement—not replace—whole-body exercise

The episode also explains why walking remains important. A short post-meal walk engages larger muscle groups and provides broader cardiovascular, mobility, and whole-body benefits. Soleus push-ups instead offer a practical alternative for situations when getting up simply isn’t possible—such as long meetings, desk work, or extended flights.

Could one of the most useful muscles for managing sedentary time be hiding right beneath your calf?

Tune in to hear the research, learn the movement, and discover how something as simple as lifting your heels may change the way you think about sitting and metabolic health.

Artificial intelligence may live in the cloud, but its impact is showing up somewhere much closer to home: your electric bill.

In this episode of vpod.ai, Mike and Susan examine how the explosive growth of AI data centers is colliding with an aging U.S. power grid, rising utility costs, local resource concerns, and an increasingly heated political debate ahead of the 2026 midterm elections.

At the center of the fight is a simple but increasingly urgent question: when massive AI facilities require new substations, transmission lines, cooling systems, and other infrastructure, who should pay for it?

The episode explores:

• Why AI data centers consume enormous amounts of electricity

• How GPU-heavy AI workloads create around-the-clock power demand

• Why data centers also require significant water resources for cooling

• How utility infrastructure costs can be distributed across local ratepayers

• The Ratepayer Protection Act and its proposed approach to shifting certain infrastructure costs toward data center operators

• Why the bill received overwhelming support in the House but stalled in the Senate

• Senator Martin Heinrich’s competing GRide Savings Act and its emphasis on community involvement, water conservation, cleaner energy, and battery storage

• The debate over renewable energy, battery capacity, diesel backup generators, and reliable baseload power

• How Senate procedural rules allowed individual lawmakers to halt both proposals

• Why Ohio has become a major political battleground over data centers and electricity prices

• How the expansion of AI infrastructure is reshaping the traditional political argument around technology investment, jobs, and economic development

The larger issue extends far beyond Washington. Data centers continue to be built, power demand continues to rise, and communities are being forced to confront the physical costs of technologies that often appear invisible to the people using them.

As AI models grow more advanced and their energy requirements increase, lawmakers, utilities, technology companies, and local communities face a difficult question: how should the financial and environmental costs of the AI infrastructure boom be divided?

Listen to the full episode for a closer look at the collision between artificial intelligence, energy infrastructure, utility bills, and U.S. politics.

The Moon may look frozen in time, but a newly discovered impact crater tells a very different story.

In this episode of vpod.ai, Mike and Susan explore the discovery of Megin Crater, a massive new lunar feature identified by NASA’s Lunar Reconnaissance Orbiter after an impact that occurred sometime between April 11 and May 22, 2024.

The crater measures roughly 728 feet across and 141 feet deep. But the most surprising discovery extends far beyond the crater itself.

Researchers detected a sprawling thermal anomaly around the impact site, where the lunar surface becomes significantly colder during the long lunar night. The episode examines how the impact’s shock wave may have disrupted and decompacted the Moon’s tightly packed regolith, creating a much larger zone of loose material around the crater.

You’ll hear about:

• How scientists discovered a new crater on a surface already covered with millions of them
• Why a large lunar impact can happen with almost no visible warning
• How NASA’s Lunar Reconnaissance Orbiter uses before-and-after imagery to spot surface changes
• What the Diviner lunar radiometer revealed about the surrounding cold zone
• Why disturbed lunar soil could create problems for astronauts, rovers, landers, and habitats
• How fresh impact sites could help engineers prepare for future Artemis missions
• Why permanent lunar infrastructure will need to account for impacts occurring miles away

The discovery offers a rare opportunity to watch lunar geology unfold almost in real time—and provides scientists with a natural laboratory for studying how major impacts alter the Moon’s surface.

As humanity moves from briefly visiting the Moon toward potentially living and working there for extended periods, understanding these hidden hazards becomes increasingly important.
