Right now, millions of men are taking this legal boner pill. Pop this little blue pill, and you become like Iron man in the bedroom. But you could also be hiding the warning signs of a future heart attack. Because here's what a doctor won't tell you. That bedroom problem. It's not what you think it is. It's not about age. It's not about stress. It's not even about your eggplant. It's your body trying to tell you something urgent, something that could save your life if you listen. But most men don't know that they should listen. So here's what I want to help you figure out in this video. Is Ed the deadly kind? Is it the kind that puts you on a countdown? Is it an early warning? And if so, how much time is on the clock? Because there are specific signs that tell you the answer. And I'm about to show you every single one. First, you gotta understand what Ed actually is. It's not the story the commercials tell you. It's not about effort. This is the truth. When most men hear the words erectile dysfunction, they instantly think it's a performance problem. And then we blame ourselves for stress, for aging, for not being in the mood anymore. And commercials reinforce the story by selling little blue pills and then promising that all you need to do is fix blood flow temporarily and you'll be fine. And society makes Ed a source of shame and something to hide, something to laugh off. Now, my friend Biolane has been dealing with Ed a lot. And this video is for him. Because of that, men almost never ask what's really happening inside their bodies. They see it as a problem in the bedroom instead of a warning for something potentially bigger. But that cultural story is dangerously incomplete. Erections don't depend on confidence or desire alone. They depend entirely on circulation. You can desire your partner, you can be fully confident. But if your circulation isn't working, it's not a matter of desire. If blood can't flow properly into the arteries of your eggplant, an erection simply won't happen. And the arteries in your eggplant are smaller than the arteries in your heart. In fact, your eggplant has some of the smallest arteries in your entire body. And yes, I am saying eggplant all the time because, well, we know it's social media. And this little problem reveals difficulties with circulation years before you feel chest pain or shortness of breath. And that's why ED is one of the earliest warning signs of vascular disease. It's your body showing you in the most visible way possible that your arteries are already struggling. If you ignore it, the same blood flow problems that are blocking an erection today could be the ones that block blood flow to your heart or your brain tomorrow. And when you think about it, it makes perfect sense. The arteries in your eggplant are only about 1 to 2 millimeters, far narrower than the main coronary arteries. Coronary arteries are the blood vessels that deliver oxygen rich blood to the heart muscle itself. And they're 3 to 4 millimeters wide. That means even a small buildup of plaque or inflammation can choke off blood flow to your eggplant first. It's like the plumbing in a house. The smallest pipes clog before the mainline backs up. And by the time plaque blocks a heart artery enough to cause chest pain, it's usually been deteriorating for years. So if you notice problems in bedroom today and you don't do anything, the same problem could reach your heart or your brain in a few short years. The problem is, when men first experience ed, the easiest path is to grab Viagra, Cialis, or another drug. And the commercials make it sound like magic. Swallow this tablet, wait a few minutes, and you can make your lady happy. But on the surface, that's exactly what does happen. The pill temporarily forces blood into the penis eggplant by increasing something called nitric oxide signaling. And that's just your body's way of telling blood vessels to relax so blood can flow and you get a short term fix. But those pills do absolutely nothing to repair the underlying issue. They don't rebuild the delicate lining of your arteries that keeps them smooth and open. They don't stop the slow chemical fire of inflammation that stiffens and scars blood vessels. And they don't make your arteries healthier. They just cover up the signal. It's like painting over rust on a car. The paint job hides the corrosion, but underneath the surface, the metal is still breaking down. And every week, the rust eats away until one day, the structure gives out completely. And that's exactly what happens when men rely on ED pills alone. You might get your sexual performance back for now. But the same disease process that was silently eating away your arteries, including the ones that feed your heart, is still going. So if you respond to ED medication only with pills, you're painting over the rest while your circulation continues to degrade. The only responsible move is to treat it as a sign that requires a full cardiovascular checkup and a metabolic reset. That's what biohacking is for. So how can you tell if your ED is just in your head or if it's a sign your heart's in trouble? It's because not all ED is the same. Sometimes it is psychological, but when the problem is mechanical, it's often the same artery damage that later causes your heart attack. Stress, anxiety, even nerve damage after an injury can temporarily block erections. And that kind usually shows up fast and unpredictably. And one day things work, and the next day they don't often comes with big changes in your stress and your mood and your workload or even really heavy workouts. You kind of know if you're depleted energetically, and then things aren't going to work as well. But when you're not depleted and they still don't work, that's when you pay attention, because vascular ED creeps in quietly, and it worsens steadily over months or years. And that difference matters because vascular ED is the type of ED that is a direct indicator that you're on the path to heart disease. So the pattern really matter. If your erections used to be reliable and now they're weaker, slower to appear, or harder to maintain, it's a red flag, especially if the decline happened gradually over months or even a couple years, rather than just an overnight change. If the erection suddenly disappears one day and the next day you're fine, it means it was probably something like stress or an ongoing issue in your relationship. And that's okay. Another key signal that's more reliable. We'll call it morning wood. Healthy arteries still create spontaneous morning erections, especially if you're managing your hormones properly. If those have just quietly disappeared. It's often because blood flow is getting worse. And there are other clues too. If you notice leg cramps when you're walking, which is a sign of poor circulation to your legs, you have frequent cold hands and feet or slower healing from small cuts and scrapes. Those are signs your vascular system is working really hard. If you ignore those early warnings and you just medicate the symptom, you're usually buying yourself only a few safe years. And once vascular ED appears, there might be a three to five year window before a man has a heart attack or a stroke if nothing changes. Or it could be much longer. In men with uncontrolled risk factors like smoking, high blood pressure, diabetes and obesity, the countdown can shrink to just a couple years. But if you catch it early and intervene, you can stop the process and even reverse a lot of the damage before it ever reaches your heart. Now, before we go any further, I'm an unlicensed biohacker. I am not a doctor, but I lecture to doctors all the time. And I'm a leader in the longevity field. And let's face it, if you want to live way longer than you're supposed to, you'd like to have working eggplant the entire time. So this is educational information, it's not medical advice. And everything I'm about to share with you, something that you can discuss with your own healthcare provider team before you make any decisions. You can even talk about it with your favorite AI. It's up to you. You're in charge of your health, nobody else. Your situation's unique. I highly recommend working with a functional medicine doctor if it's within your means. If not, take ownership of your health and do your research. Work with whatever doctor you have and make things work because it's important. It's not just about your eggplant. It's about your relationship. It's about your heart, it's about your mind. And it's about how long you're going to live. So here's what I would do if I had to help a friend like Biolane in this situation. First, I would tell him to stop seeing Ed as an embarrassing secret and starting to see it as data. That means that he should get a good cardiovascular checkup. And second, you don't need to self diagnose. ED can have a lot of causes and you want to do the detective work to figure out what it is. You can ask your doctor if your doctor's an expert in functional medicine. Is this vascular or is it something else? And if it's vascular. Talk to a qualified cardiologist. And remember, not all cardiologists are the same. The most important labs that I would run would be labs looking at inflammation because this will be reflected in your erections. Homocysteine C reactive protein and Lp PLA2, which is an enzyme that's released from damage to your arteries. And you also want to get your sex hormones. If your testosterone is low, that could be part of the problem. Once you have the data and you know what's going on, it's time for lifestyle reset and and it's time to add some supplements that will support your arteries throughout the body. And for this, there's four things I would recommend.
A
Is the air you're breathing making you sick? Just because you don't see mold doesn't mean it isn't there. My friend Jason Earle has been on a mission for over two decades to help people understand the hidden role of indoor air in their health. He's one of the world's leading experts on mold and indoor air quality. And he created the Got Mold Test kit to make professional grade air testing simple. Simple and accessible. It uses cutting edge air sampling tech that top inspectors trust. And it's engineered for you at a fraction of the cost. It takes just minutes to get samples using the patented Biovac air sampling pump. Then you send them prepaid to one of the most prestigious microbiology labs in the world. No guesswork, no paperwork and no hidden fees. You get fast results, intuitive reports and great support. And since you keep the pump, you can retest anytime for less. It even comes with a lifetime warranty. Mold may be invisible, but its impact isn't. This kit helps you understand your environment so you can take action for your health. Go to gotmold.com and use code DAVE10 to save 10% and see what's in your air. Because the best biohackers don't guess. They test.

You must protect something called the glycocalyx. It's the very thinnest, most, most fragile part of your blood vessels. A supplement called Arterosil will help this problem. It's got 15 years of clinical data behind it. I take it every day. Another one called Vasconox from the same company increases nitric oxide, which is required for that morning kickstand. And the combination of those two can be incredibly powerful. You can go to calroy.com Dave and they'll give you a discount on them. So you might think I'm capping on Cialis right now because they have no Riz. But the reality is I take 5mg of Cialis every single night before I go to bed, which is a microdose. And microdosing Cialis will support your vasculature for longer periods of time and is associated with a reduction in Alzheimer's. And the final thing you might want to consider is a very expensive thing that works as well as Cialis in some people, and it is taking an aspirin, an 81 milligram aspirin regularly. And if you do that, take it with food to protect yourself from gastric bleeding. But it turns out aspirin can also help vascular ED. So there you go. Artyrosil and Vasconox from Kalroy.com Dave and you can look at microdosing Cialis at 5 milligrams a night if your doctor agrees. Or you can get a prescription for it and you can look at taking a baby aspirin. It's pretty straightforward, but you're going to need to do some more work. And one of those things would be quit smoking completely. Smoking is bad for you. If you microdose nicotine at under 5 milligrams a day, it's unlikely to affect your erections. High doses of nicotine, if you're just stuffing ZINN in every 10 minutes, that can affect erections as well. But smoking itself is so bad, and it's one of the fastest ways to destroy mitochondrial function and completely lose your morning kickstand. Cut alcohol to almost nothing. Alcohol is not your friend in the bedroom. And a glass of wine occasionally is something you might enjoy. But don't tell yourself it's good for you. And don't do it every night, because it's going to affect your liver and spike inflammation. And you've got to get control of your stress. If you have a lot of cortisol floating around, it will clamp down on your arteries like a vice. And that's why meditation or breath work, even a simple gratitude practice, or just snuggling with your partner and doing some deep breaths and just relaxing and connecting might make a big difference, because especially for men, that drops our stress. And if we do it right, it also drops the stress of our partner. And you've got to address high blood sugar, because high blood sugar creates high blood pressure, which can be part of the problem. And we do that by looking at our nutrition. So you stop eating industrial foods and seed oils. They just don't work well. Processed foods are bad for you and they don't even taste that Good compared to real food. You just have to try the real food. You're getting oxidized oils that are unstable and they do inflame your arterial walls and form fact studies show that it's not fat from butter that's clogging your arteries, it's polyunsaturated fat. Wild caught salmon and sardines can give you some clean Omega 3s and so can some Omega 3 supplements, as long as they're not the ones that are oxidized. The war on saturated fat needs to end. Grass fed butter or ghee or beef fat from grass fed beef. It provides nutrients you can't get anywhere else. And this is the building block for, for testosterone inside your body. And if you're low testosterone, even if your arteries are healthy, things are gonna work the way you want them to. And of course you need to move, but you don't have to beat yourself up in the gym. You don't have to do eight hours of zone two every week because you probably have a life. And if you do eight hours of Zone two, you probably don't have enough time or energy to go on a date anyway. But going for a walk, even a short walk after meals, it's non negotiable. You just need to get the blood moving. And even if you do all this, there's still a deeper driver that just about no one talks about. Your erections and your heart run on the same cellular energy source. And if that energy source is off, no amount of pills or jogging is going to restore healthy erections. It's not going to protect your heart. Most of us don't know what actually powers an erection. It's not just blood. It's a highly coordinated process that depends on your body's ability to produce nitric oxide and relax those smooth muscle tissues that are inside the arteries. That process requires energy, and the source of that energy is mitochondria. They are stress sensors. They are little computers, but they're also the power plants inside your cells that decide where to allocate energy. They turn food and oxygen into usable fuel. When your mitochondria stop working well, your arteries lose the ability to expand. And if they can't expand, you know your eggplant can't expand either. And that means signs of ED show up as one of the earliest visible signs of mitochondrial decline, long before you have a heart attack. And that flips the story completely. ED is a problem of circulation at the surface level. But if you go deeper, it's a problem of energy inside your cells. If your mitochondria don't have enough power, the arteries in your penis. Oop. The arteries in your eggplant and your heart both fail to function. It's not two separate problems. It's one shared system failure. That's why if you want to reverse ED and you want to protect your heart, the most powerful thing you can do is just restore the health of your mitochondria. When those little power plants are recharged, blood flow improves. Nitric oxide signaling strengthens both your performance in the bedroom and your survival in life. Improve together. And the first step there, get better sleep and protect it. Keep your room really dark, make it cool at night, and follow a consistent schedule, because mitochondria repair themselves most when you're sleeping. The second step is expose your body to natural light, especially in the morning sunlight. Or red light therapy. Yes, red light therapy directly on the eggplant will stimulate mitochondria to make more energy and more nitric oxide. And this is really important. Reduce the toxins that poison your mitochondria every day, like mold in your home, plastics in your kitchen, or even heavy metals that are in your water. Less toxins, better morning kickstand. It's that straightforward. So clean your environment and your cells can finally breathe again. But even if you fix your mitochondria, that alone isn't going to do it. There's one other silent force that attacks your arteries every day, and it does drain your energy. It eats away at the lining of the blood vessels, and it's chronic inflammation, also known as inflammaging. Most people think inflammation is something obvious, like a swollen ankle after an injury or sore throat during a cold. But the deadliest form of inflammation is silent. It doesn't hurt, it doesn't show up on the surface, but it just eats away your arteries and the rest of you day after day. Chronic inflammation makes blood vessels stiff instead of elastic, narrowing the space for blood to flow. What makes chronic inflammation so dangerous, especially especially with stiff arteries, is that the risk factors are everywhere. Before I tell you the risk factors, you can measure how stiff your arteries are. It's part of an advanced longevity assessment. My arteries are those of a 31 year old, and my chronological age is 52 as I'm recording this. So, yes, my arteries are 20 years younger because I do what I just told you about in this video. It's that big of a deal. And you can measure the changes over time. So what are the things that are causing this inflammating of your arteries? Smoking, the worst thing you can do. Vaping actually is even worse than smoking, so don't do either one. And obesity drives constant chemical stress. As a guy who used to weigh 300 pounds, I don't do that anymore. And I've taught millions of people how to not do it. And if you want to do that, just keep following here. Like, we can help you lose the weight. It's not as hard as you think it is. Behind all that, though, is diabetes. It bathes your arteries in high blood sugar, and what it does is it stiffens the lining of your arteries even more. If you think of onions browning in a pan, that's what sugar does to protein. And your arteries are getting browned by high blood sugar, and that leads to stiff arteries, which gives you high blood pressure. And that just puts more force on your blood vessels. And of course, they're gonna get ground down faster. And even a lot of young men in their 30s and 40s are struggling now with ED, and they think it's about their willpower. It's not. It's about inflammation. In other words, your body's been screaming for years that there might be a heart attack in your future, but we only notice it in the bedroom on Friday night, and it's time to pay a little bit more attention to that every single morning. And one of the things that helps is just calming inflammation, because that's going to restore both sexual health and heart health. Here's what you can do to reduce inflammation. And these are all lifestyle changes. Intermittent fasting can give your body a daily break from constant digestion, can lower stress on your system altogether. Cold exposure, even just a cold shower for two minutes in the morning can calm those inflammatory pathways. And cardio, specifically rehit, or steady, moderate exercise, just going for a walk can improve circulation without overstressing anything. And finally, don't ignore emotional inflammation. If you have resentment, you have stress, job stress, relationship stress, kid stress, constant mental tension. They light the same fires of inflammation that junk food does. So doing a practice, whether it's meditation, breath work, neurofeedback, even a forgiveness practice, like I teach about my last book, all of those, calm inflammation at the very deepest level. So part of this is about learning to chill, but a lot of it's about learning to manage inflammation and learning to manage blood flow in your body so that you have recreational blood flow and cognitive blood flow and cardiac blood flow way beyond 100. And there's an old saying that says the body whispers before it screams, and ED is the whisper, and the heart attack is the scream. And the difference between the two is really simple. It's whether you paid attention when it mattered. So pay attention now while you still can, and check the description for a short list of the things you can do.
