The news could have been devastating, but I was actually excited to have the hard data. I felt in control for the first time because I finally had real information and knew exactly what I needed to change. This was proof that it wasn’t just a deficiency in my effort or some sort of moral failing. It’s common to see your hormone levels drop off around middle age, but not in your twenties. Now I had proof that I was aging prematurely and not just lazy, and I was determined to turn things around.
Dr. Miller and I came up with a plan for me to restore my hormone levels to that of a young man using bioidentical hormones and continue to track my data. The hormones made an enormous difference right away. I got my energy back along with my zest for life. It gave me so much hope to know that I could actually reverse some of my health issues, which I now knew were common symptoms of aging. So when I heard about an anti-aging nonprofit group in Silicon Valley, now called the Silicon Valley Health Institute (SVHI), I decided to check it out.
As I sat there at the first SVHI meeting listening to people who were at least triple my age, I felt completely at home. These were my people, I realized. I had more in common with them than I did with most of my peers, except these people had decades of wisdom I didn’t. After the meeting, I stayed for a long time talking with a board member who at eighty-five years old was kicking ass and full of energy in a way that was amazing and seemed totally impossible to me—but that I was inspired to replicate.
For the next four years I focused completely on learning as much as I could about the human body. I studied medical literature, read thousands of studies, talked to researchers, and spent all my free time at SVHI learning from seniors who were actively reversing their own symptoms of aging. This completely changed the way I thought about health, as well as aging. I learned that there is no one thing that causes disease or that leads us to age. Instead, aging is death by a thousand cuts, the cumulative damage caused by little insults stemming mostly from our environment.
Then in the year 2000 I found a former Johns Hopkins surgeon who ordered a litany of tests, including some allergy tests that showed I was highly allergic to the eight most common types of toxic mold. That was the smoking gun. In order for my immune system to be sensitized to those toxic molds, I must have been exposed to high levels of them, which wreaked havoc on my cells. This was one of the unexplained environmental factors that had made me age so rapidly.
My premature aging makes complete sense to me now. Mitochondria, which are bacteria embedded in most of our cells, power our energy production. Back when we were single-celled creatures, we became host cells for ingested bacteria. Over millions of years of evolution, the host cell became humans, the ingested bacteria became mitochondria, and today neither of us can survive without the other. Mitochondria are not of human origin; they even have their own DNA. And what has posed a lethal threat to bacteria since the beginning of time? Mold.
This means the very powerhouses of my cells were constantly engaged in a battle with their mortal enemy, and this fight left behind many casualties. When cells are under chronic stress, their mitochondria cannot make energy efficiently. This leads to an increase in the production of molecules called reactive oxygen species (ROSs), also known as free radicals. ROSs are unstable molecules that contain atoms with unpaired electrons, making them highly reactive. When an excess of free radicals are present in cells, they cause a chemical reaction that damages your cellular structures in a process called oxidation.
This is exactly what happens as you age, whether or not toxic mold is present in your life: Mitochondria function steadily declines, leading to an increase in free radicals, which damage your cells. In response, your body sends vitamin C from food to the liver so it can produce antioxidants, which fight off free radicals. The problem with this process is that it leaves you without enough vitamin C to produce collagen, the protein in the connective tissue of your skin, teeth, bones, organs, and cartilage. Vitamin C interacts with amino acids to build collagen, but only if you have enough of it. Your body will gladly sacrifice healthy blood vessels and skin in favor of fighting off free radicals that are draining its energy source.
This is precisely why I had stretch marks and vascular issues (manifested as nosebleeds) and why most people don’t develop these symptoms until they’re much older. The fight in my body between my onboard bacteria and mold left me constantly depleted of antioxidants. And my mold-damaged mitochondria also laid the groundwork for prediabetes, poor blood flow to the brain, arthritis, cognitive dysfunction, and, according to one doctor, a high risk of stroke and heart attack. I was still in my twenties, but I was biologically old because my mitochondria were slowing down. And it really pissed me off.
MITOCHONDRIA AND THE FOUR KILLERS
As I fought my way back from experiencing the many symptoms of aging, my likelihood of dying from the Four Killers dropped dramatically. That’s because—surprise, surprise—they all have one underlying issue in common: the cumulative damage to your cells, and in particular, to your mitochondria, that takes place over the course of a lifetime. This damage occurs in all of us, though at varying rates. Some damage stems from the bad choices we make, but much of it is simply the price we pay for the basic functions that support life—like metabolizing food and breathing.
You die a little bit every day from these cuts that make you weaker in the short term and hasten your decline in the long term. Staying alive requires avoiding as many of those cuts as possible, but they are all around you—in your food, your air, your light sources, and throughout your environment. You may not associate these cuts with your likelihood of aging prematurely or of developing a degenerative disease, but like every other aspect of your biology, they are all connected. The cuts lead to aging, aging leads to disease, and disease leads to death.
If you’re in your twenties or thirties, you may think you’re in the clear—that these cumulative cuts aren’t affecting you yet. But the cuts from bad choices or a toxic environment begin to add up from an early age—and they’re hurting you even if you’re not currently feeling their effects (such as weight gain, brain fog, muffin top, and fatigue). And it’s a lot easier to avoid damage to your mitochondria than it is to reverse it later.
Your mitochondria are responsible for extracting energy from the food you eat, and then combining it with oxygen to produce a chemical called adenosine triphosphate (ATP), which stores the energy your cells need to function. When your mitochondria conduct this process efficiently, they produce lots of energy so you can perform at your greatest potential—like a young person. But if your mitochondria become damaged or dysfunctional as you age, they begin producing an excess of free radicals in the process, which leak into the surrounding cells and lay the groundwork for the Four Killers. Congratulations, you are now old.
Even young, efficient mitochondria produce some free radicals as by-products of creating ATP, but they also make antioxidants, compounds that inhibit the damaging effects of free radicals. This is why products containing antioxidants have “anti-aging” properties. While popping antioxidant supplements and using skin-care products containing antioxidant-rich ingredients are worthwhile interventions, they are, frankly, the low-hanging fruit of our Super Human tree. For you to truly remain young, those antioxidants have to be produced by your body—your mitochondria must create at least as many of them as it does free radicals. When your mitochondria become inefficient, they make an excess of free radicals and fewer antioxidants. And you can’t slather enough serums onto your skin to fully counteract the damage created by this imbalance.
Your mitochondria are also in charge of triggering cellular apoptosis, programmed cell death that occurs when a cell is old and/or dysfunctional. If your mitochondria are sluggish, they may not trigger apoptosis at the right times, which can result in healthy cells dying off before they should or dysfunctional
