Life expectancy has been on a steady global rise for longer than I've been alive.

Meanwhile ... the United States has fallen to 48th on the list of countries with the highest life expectancy.
Hong Kong tops the list with an average life expectancy of 85.63 overall - and 88.26 years for females.
For comparison, the U.S.'s average life expectancy is only 79.46.
Many factors potentially impact the findings, for example, the average height and weight of a population (with shorter & lighter people tending to live longer), diet, healthcare system, and work/life balance.
While some of this is out of your control (OK, a lot of it is) - there are definitely things you can do to increase your healthy lifespan. Meanwhile, some people like Bryan Johnson are doing everything they can to live forever.
Popular Mechanics put together a video series called How to Live Forever, or Die Trying, where they interview scientists and anti-aging gurus to give you insight into pursuing a future without death.
Unfortunately, recent science has shown that adults in their mid-40s to early 60s begin to experience significant changes in their alcohol, caffeine, and lipid metabolism, an increase in risk of cardiovascular disease, and a noticeable decrease in their skin and muscle health. When you hit your 60s, you also begin to see negative changes in carbohydrate metabolism, immune regulation, kidney function, and a further decline in the previously mentioned factors.
Here's the good news. Not only is science and technology getting better, but you're always in control. You can make lifestyle changes to increase your longevity, and you can also find supplements, treatments, and protocols that can reverse those factors of aging. Even simple measures like increasing your physical activity or avoiding alcohol before bed can make a massive difference.
They say a healthy person has thousands of dreams, but an unhealthy person only has one.
That is one of the reasons I spend so much time and energy thinking about staying healthy, fit, and vital.
Focusing on the positive is important ... But to extend your healthy lifespan, you have to start by telling the truth and finding out what you and your body struggle with the most.
A doctor friend gave me some advice. He said it doesn't matter if you are on top of 9 out of 10 things ... it's the 10th that kills you.
Despite our best efforts, Mother Nature remains undefeated.
With that said, here are some of my previous articles on longevity and health:
The goal isn't just to stay alive longer; it's to live life to its fullest for as long as possible.
I recently joined a fantastic mastermind group called DaVinci 50, run by Lisa and Richard Rossi. It brings together a remarkable collection of medical professionals and entrepreneurs focused on the latest research, treatments, and opportunities in health and longevity.
Another great tool I rely on is Advanced Body Scan. Early detection is crucial, but so is tracking the history of your scans to monitor changes over time. In my opinion, the most valuable scan is always the next one.
Additionally, I use a growing list of trackers and biometric devices to measure my heart rate, along with apps and tools for mindfulness, breathwork, and journaling. Together, these practices recognize that mind, body, and spirit combine to define how you live your life.
To end this post, I'll use a farewell phrase I heard often while growing up ... it translates roughly to "go in health, come in health, and be healthy." It's a beautiful way to wish someone well on their journey, emphasizing the importance of health and well-being.
I hope you found something interesting. Let me know what things and practices work best for you.
The Cities Of The Future
Population Growth: A Critical Lens on Human History
Studying historical changes in human population trends offers valuable insights into the factors that have propelled or hindered human development throughout time.
From ancient civilizations to modern metropolises, population dynamics have influenced everything from economic prosperity to social structures.
A Window Into Our Past Gives Us a Glimpse at Our Future.
By studying this critical aspect of human history, we can gain valuable insights into the past, present, and future of societies.
Population growth is a complex and multifaceted phenomenon with far-reaching implications. It offers a fascinating glimpse into the demographic trends that have shaped our world and continue to influence our trajectory.
Historically, human populations grew steadily but relatively slowly ... until something changed that. And the implications are stunning.
Scientists estimate that humans have existed for over 130,000 years. However, it took until 1804 for us to reach 1 Billion. We doubled that population by 1927 (123 years later) and then doubled it again only 47 years later (which was 1974).
Looking back, early population growth was driven by the agricultural revolution. Since 1804, the Industrial Revolution, health and safety advances, along with technology, have significantly improved quality of life, spurring the rapid population growth. Here is a quick overview of some of the key factors.
Shaping the Future
It’s hard to predict some things accurately. So, one goal in data science is to figure out what we can “know” in order to “guess” less.
Population growth is a prime example. One of the easiest ways to predict how many 60-year-olds there will be in 40 years is to look at how many 20-year-olds there are today. Obviously, the number won’t be exact, but it’s a pretty good head start.
This principle of using known data to make educated predictions applies to many aspects of future planning, including urban development and resource allocation. By leveraging current demographic information, we can better prepare for the challenges and opportunities that will likely impact the cities of tomorrow.
Why It Matters
Population growth is more than just a numerical metric. It is a fundamental lens through which we can analyze:
Have World Population Growth Numbers Peaked?
World population growth rates peaked in the late 1960s and have declined sharply in the past four decades, but we’re still on a positive trend. We’re expected to reach 9 billion people by 2050, but a lot of that growth comes from developing countries – they also almost exclusively come from urban areas.

Urbanization: Megacities
In the 1800’s, about 10% of the population lived in urban areas. Since 2014, over 50% of the world’s population has lived in urban areas – today it’s approximately 55%. That number is growing.
Ironically, as we grow more digitally connected, our world is shrinking, and our populations are concentrating.
An interesting consequence of this rapid urbanization and population growth in developing countries has been the increased development of Megacities – defined as cities with populations greater than 10 million. Today, there are 33 megacities – more than triple the number in the 1990s.
This creates a set of interesting opportunities and challenges.
For example, how will these cities deal with infrastructure – sanitation, transportation, etc?

Today, in most high-income countries, about 80% of the population lives in urban areas - contrasting the primarily rural populations of lower-income countries.
As a result, we see many of these megacities forming in developing countries. As a side note, we’re also seeing countries like China making substantial investments and alliances in these developing areas. This is likely done to profit from the expected growth and also to shift the future balance of power in their favor. Sometimes, it makes sense to focus on the marathon and not just the sprint.
It’s interesting how the world can become more decentralized - and more globalized - amidst a contraction of where people live.
