why we age....
Jun 14, 2020
Healthcare today is reactive, retrospective, bureaucratic and expensive. It's sick care, not healthcare.
But that is radically changing at an exponential rate.
Last year alone, biotech venture capital exceeded $14 billion invested in biopharma startups globally, encompassing those leading the charge against aging. And the year prior, we witnessed a record-high of nearly $800 million invested in longevity startups alone (over double the approximate $400 million invested in 2017).
Over the next few weeks, I’ll be taking a deep dive into aging, longevity, and healthcare technologies that are converging to dramatically extend the healthy human lifespan, disrupting a soon-to-surpass $10 trillion healthcare system in the process.
I’ll begin the series by explaining the nine hallmarks of aging, as explained in this journal article.
Next, I’ll break down the emerging technologies and initiatives working to combat these nine hallmarks.
Finally, I’ll explore the transformative implications of dramatically extending the human health span.
In this blog, we'll discuss:
- Why the healthcare system is broken
- Why, despite this, we live in the healthiest time in human history
- The 9 Mechanisms of Aging
Let’s dive in.
The System is Broken — Here’s the Data:
- Doctors spend $210 billion per year on procedures that aren’t based on patient need, but fear of liability.
- Americans spend, on average, $11,172 per person on healthcare — more than the residents of any other country on Earth.
- Prescription drugs cost around 50 percent more in the U.S. than in other industrialized countries.
- At current rates, by 2025, nearly 25 percent of the U.S. GDP will be spent on healthcare.
- It takes 12 years and $359 million, on average, to take a new drug from the lab to a patient.
- Only 5 in 5,000 of these new drugs proceed to human testing. From there, only 1 of those 5 is actually approved for human use.
And Yet, We Live in the Healthiest Time in Human History:
Consider these insights, which I adapted from Max Roser’s excellent database Our World in Data:
- In 1841, a 5-year-old had a life expectancy of 55 years. Today, a 5-year old can expect to live 82 years — an increase of 27 years.
- We’re seeing a dramatic increase in healthspan. In 1845, a newborn would expect to live to 40 years old. For a 70-year-old, that number became 79. Now, people of all ages can expect to live to be 81 to 86 years old.
- 100 years ago, 1 in 3 children would die before the age of 5. Today, the child mortality rate has fallen to just 4.3 percent.
- Meanwhile, the cancer mortality rate has declined 27 percent over the past 25 years.
Figure: Around the globe, life expectancy has doubled since the 1800s.

The 9 Mechanisms of Aging:

Longevity, healthcare, and aging are intimately linked.
With better healthcare, we can better treat some of the leading causes of death, impacting how long we live.
By investigating how to treat diseases, we’ll inevitably better understand what causes these diseases in the first place, which directly correlates to why we age.
Following are the nine hallmarks of aging. I’ll share examples of health-tech and longevity technologies addressing each of these in coming weeks.
- Genomic instability: As we age, the environment and normal cellular processes cause damage to our genes. Activities like flying at high altitude, for example, expose us to increased radiation or free radicals. This damage compounds over the course of life and is known to accelerate aging.
- Telomere attrition: Each strand of DNA in the body (known as chromosomes) is capped by telomeres. These short snippets of DNA repeated thousands of times are designed to protect the bulk of the chromosome. Telomeres shorten as our DNA replicates; if a telomere reaches a certain critical shortness, a cell will stop dividing, resulting in increased incidence of disease.
- Epigenetic alterations: Over time, environmental factors will change how genes are expressed, i.e., how certain sequences of DNA are read and the instruction set implemented.
- Loss of proteostasis: Over time, different proteins in our body will no longer fold and function as they are supposed to, resulting in diseases ranging from cancer to neurological disorders.
- Deregulated nutrient-sensing: Nutrient levels in the body can influence various metabolic pathways. Among the affected parts of these pathways are proteins like IGF-1, mTOR, sirtuins, and AMPK. Changing levels of these proteins’ pathways has implications on longevity.
- Mitochondrial dysfunction: Mitochondria (our cellular power plants) begin to decline in performance as we age. Decreased performance results in excess fatigue and other symptoms of chronic illnesses associated with aging.
- Cellular senescence: As cells age, they stop dividing and cannot be removed from the body. They build up and typically cause increased inflammation.
- Stem cell exhaustion: As we age, our supply of stem cells begins to diminish as much as 100 to 10,000-fold in different tissues and organs. In addition, stem cells undergo genetic mutations, which reduce their quality and effectiveness at renovating and repairing the body.
- Altered intercellular communication: The communication mechanisms that cells use are disrupted as cells age, resulting in decreased ability to transmit information between cells.
Over the past 200 years, we have seen an abundance of healthcare technologies enable a massive lifespan boom.
Now, exponential technologies like artificial intelligence, 3D printing and sensors, as well as tremendous advancements in genomics, stem cell research, chemistry and many other fields, are beginning to tackle the fundamental issues of why we age.
In next week's blog, we will dive into how genome sequencing and editing, along with new classes of drugs, are augmenting our biology to further extend our healthy lives.
What will you be able to achieve with an extra 30 to 50 healthy years (or longer) in your lifespan? Personally, I’m excited for a near-infinite lifespan to take on Moonshots.
(1) Platinum Longevity & Immunity Trip: This August 19-23, 2020 and September 16-20, 2020, I'm taking two groups of VIP entrepreneurs and investors on what I call my “Platinum Longevity & Immunity Trip” to San Francisco & San Diego.
Each trip will be a 5-Star (luxury) deep dive to meet 20+ companies and 30+ scientists/physicians and entrepreneurs who are leading the charge against age-related diseases and extending the human healthspan. We will also be visiting the top labs and scientists developing the diagnostics, anti-virals, vaccines and therapeutics fighting COVID-19.
Both trips are identical (with only 24 participants per trip). I will spend all 5-days with you as your private guide and provocateur. Through this personalized, action-packed program, my mission is to give you first-hand exposure to the major players, scientists, companies and treatments in the longevity and vitality arena. All your questions answered. Early access to cutting-edge treatments and products. And a behind-the scenes view of tomorrow’s longevity revolution.
Both trips are nearly sold out. To learn more and lock in your seat, visit our website here.
