The 3 Hard Truths About Longevity Nobody Wants to Admit

Last week, a VC asked me to settle a marital dispute. His wife ate an apple every afternoon. He wanted her to switch to $8 macro-balanced longevity bars because "fruit is just sugar." His entire diet was balanced, although 90% was processed.

This is modern longevity: optimizing the microscopic while ignoring the obvious.

As a Stanford-trained physician founder practicing longevity medicine and advising health companies, I see both sides of this industry—the exam room reality and the marketing machine. The gap between what we know and what we're sold has never been wider.

Here are three hard truths about longevity, plus a practical guide to navigate the noise.

Truth #1: We Can't Extend Maximum Human Lifespan (Yet)

Modern medicine has added decades to average life expectancy through vaccines, antibiotics, and cardiac care. But what the industry doesn’t advertise? There is no solid evidence that any drug, diet, or supplement can extend maximum human lifespan.

Short Hack Long Life

Cycle your plasma to slow aging

Your plasma carries damaged proteins, waste products, and inflammatory signals that build up over time.

A 2025 study showed that just one round of therapeutic plasma exchange (TPE) can significantly reverse your biological age.

But TPE costs up to $10,000 per session.

The good news?
Regular plasma donations offer a free alternative.
They remove the same harmful byproducts and even pay you.

How to cycle your plasma:

🧪 Each donation removes ~800 mL of plasma
🧍 Your body holds ~4 L of plasma
🔄 That means 5 donations = full cycle
📅 Donate 2× per week for 2.5 weeks to complete one full cycle

→ Repeat this once per quarter to support healthy aging

It’s free. It helps others. And it may be one of the most underrated regeneration tools available today.

Lithium Microdosing

Discussion: 
Members discussed micro-dosing lithium, noting challenges with dosing and different forms. Some referenced studies suggesting potential neuroprotective effects, but the group stressed caution and individual variability.

Consider this:
• If exploring supplements, be clear on dosage and form — labels can be confusing.
• Work with a professional and track labs if you consider experimenting.

Genetic Testing

Discussion: 
Members debated the value of genetic testing. Some found it insightful for tailoring medication or lifestyle, while others felt overwhelmed by too much data. Usefulness depends on personality and health goals.

Consider this:
• Decide upfront what you want to learn (medication response vs. general risks).
• Seek professional guidance to interpret results and avoid unnecessary anxiety.
