3D printing might save your life one day. It's transforming medicine and health care.
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Imagine that a health emergency strikes and you need an organ transplant – say, a heart. You get your name on a transplant list, but you find out there's a waiting period of six months. Tens of thousands of people find themselves in this dire situation every year. But 3D printing has the potential to change that forever.
The technology could usher in a future where transplantable organs can be printed not only cheaply, but also to the exact anatomical specifications of each individual patient.
What other innovations could 3D printing bring to medicine and health care? The sky is the limit, according to Dr. Todd Goldstein, a researcher with the corporate venturing arm of Northwell Health, New York State's largest health care provider and an industry leader in 3D-printing research and development.
"It comes down to what people can think up and dream up what they want to use 3D printing for," Goldstein says. "Ideally, you would hope that 50 years from now you'd have on-demand, 3D printing of organs."
While that's still on the horizon for researchers, 3D printing is already improving lives by revolutionizing medicine in three key areas.
Printing realistic, customized organ models
3D printers can take images from MRI, PET, sonography or other technologies and convert them into life-size, three-dimensional models of patients' organs. These models serve as hands-on visualization tools that help surgeons plan the best approaches for complex procedures.
They also allow doctors to customize patient-specific models prior to surgery. For example, Northwell employs 3D printing in several clinical applications:
- Tumor resection models clearly highlight the tumor and surrounding tissue
- Orthopedic models are useful for pre-surgery measuring and medical device adjustments
- Vascular models identify malformations in organs, tumors, sliced chambers, blood flow, valves, muscle tissue, and calcifications
- Dentistry oral implants and appliances can be created in just one day, significantly reducing wait periods for Northwell dentists and their patients
Using realistic models not only delivers better health results but also shortens operating times. That gives patients less time under anesthesia, and hospitals potential savings of millions of dollars over just a few years.
Being able to visualize procedures before they occur also helps to comfort patients and their families. Take, for instance, the case of Barnaby Goberdhan, a man who discovered that his young son, Isaiah, had an aggressive tumor in his palate. Goberdhan met with Neha A. Patel, MD, a pediatric otolaryngologist at Cohen Children's Medical Center, a Northwell Health hospital, to discuss the procedure and learn about it with help from a 3D-printed model.
"Having a 3D printed depiction of my son was really helpful when talking with the doctor about his surgery," said Mr. Goberdhan. "The doctor was able to do more than talk me through what they were going to do – Dr. Patel showed me. There is almost nothing more frightening and stressful than having your child go through surgery. There were several options Dr. Patel walked us through for the best way to preserve Isaiah's teeth and prevent additional cuts within his mouth. I wanted all of my questions answered so I could be less fearful and more prepared to talk my son through what he was about to face. I wanted Isaiah to feel prepared. With the 3D model, we both felt more at ease."
For years, 3D printing surgical models was prohibitively expensive. Now, more affordable systems such as Formlabs' Form Cell give more hospitals across the country access to the technology in order to produce realistic, patient-specific models, usually within one day.

While 3D-printed organs are a long way in the future, today's technology is well suited for manufacturing prosthetics. 3D-printed prosthetics are often remarkably more affordable and personalized than their traditional counterparts. That's a big deal for many families, especially those with children who outgrow prosthetics and are forced to buy new ones.
One recent breakthrough in 3D-printed prosthetics came when Dan Lasko, a former Marine who lost the lower part of his left leg in Afghanistan, wanted the ability to swim with his prosthetic leg. Wearing prosthetics in water has been possible for years, but they typically slow swimmers down. No device had been able to go seamlessly from land to water or to help propel its wearer through the water.
To fix that, Northwell Health recently funded a project that developed The Fin – the world's first truly amphibious prosthetic. With The Fin, Lasko and his family can go straight into the pool from the locker room – or the diving board.
"I got back in the pool with my two young sons and for the first time was able to dive into the pool with them," Lasko said.
3D-printed prosthetics will help improve the daily lives of the nearly 2 million Americans who've lost a limb. That's promising because the increasing prevalence of Type 2 diabetes is expected to greatly increase the number of amputees in the U.S., according to a study published in the Archives of Physical Medicine and Rehabilitation.
For years, 3D printers have manufactured various products: phone cases, toys, and even operational guns. To produce these objects, the machines heat a raw material, typically plastic, and build the object layer-by-layer according to a particular design.
3D bioprinting, a young field developed by researchers with Northwell Health, may someday perform the same process but instead with living cells in a raw material called bioink.
Daniel A. Grande, director at the Orthopedic Research Laboratory in the Feinstein Institute for Medical Research, an arm of Northwell Health, said he and his team first pursued 3D bioprinting by modifying 3D printers so they'd accept living cells.
"My initial concept of 3D printing was early studies that looked at modifying ink-jet printers, where we incorporate a bioink that includes cells within a delivery vehicle," Grande says. "That hydrogel can then be polymerized, or hardened, upon heat or UV-light stimulation, so that we can actually make a complex structure, three-dimensionally, that incorporates living cells. The hardened hydro-gel is then able to keep the cells alive and viable. It's also biocompatible, so it can be safely implanted in humans."
It's a promising enterprise, and it can radically change how we experience medical care.
"3D bioprinting's potential is almost limitless and has the potential to replace many different parts of the human body," says Michael Dowling, president and CEO at Northwell Health, and author of Health Care Reboot. "Researchers envision a future with 3D printers in every emergency room, where doctors are able to print emergency implants of organs and bones on demand and revolutionize the way medicine is practiced."
Dr. Todd Goldstein explains more about 3D bioprinting below:
Starling flocks, schools of fish, and clouds of insects all agree.
- Scientists discover that active articles take a pass on Newton's Second Law.
- Active particles exist in a "swirlonic" state of matter.
- Swirlonic behavior explains some of the more dazzling natural phenomena such as starling swarms and shape-shifting schools of fish.

Credit: Wikimedia Commons/Big Think<p>According to <a href="https://www.physicsclassroom.com/class/newtlaws/Lesson-3/Newton-s-Second-Law" target="_blank">Newton's Second Law</a>, the acceleration of an object depends on both the force acting upon it and the object's mass. Its acceleration increases in accordance with the force being exerted, and as its mass increases, the object's acceleration decreases. These things don't happen wth swirlons.</p><p>It appears that the Second Law relates only to passive, non-living objects at small and large scales. Swirlons, however, are comprised of active, living matter that moves courtesy of its own internal force. In this context, individual starlings are analogous to self-propelled particles within the larger swirlonic object, their flock.</p>

They were interested in better understanding the movement of human crowds evacuating a crowded space, and these particles served as human stand-ins.</p><p>The word "swirlonic" comes from the circular direction in which the scientists witnessed their particles milling about in clusters that operated together as larger quasi-particles.</p><p>"We were completely baffled," <a href="https://le.ac.uk/news/2021/february/swirlonic" target="_blank">says</a> Brilliantov, "to witness how these quasi-particles swirl within active matter, behaving like individual super-particles with surprising properties including not moving with acceleration when force is applied, and coalescing upon collision to form swirlons of a larger mass."</p><p>Brilliantov tells <a href="https://www.livescience.com/swirlonic-matter-unusual-behavor.html" target="_blank" rel="noopener noreferrer">Live Science</a>, "[They] just move with a constant velocity, which is absolutely surprising."</p><p>It's not the first time such behavior has been seen, but the first time it's been identified as a distinct state of matter. Says Brilliantov, "These patterns have previously been observed for animals at different evolution stages, ranging from plant-animal worms and insects to fish, but rather as singular structures, not as a phase which borders other phases, resembling gaseous and liquid phases of 'normal' matter."</p><p>The researchers also saw that swirlonic particles operate on a sort of "one for all, all for one" basis. With passive particles such as, for example, water, different individual particles can exist in different states: some may evaporate into gas as others remain as liquid. The models of active particles, on the other hand, stuck together in the same state as either a liquid, solid, or gas.</p>
Moving forward, and back, or up, or down together<p>Brilliantov and his colleagues hope to explore swirlons further, moving beyond their simulation into real-world investigations and experiments.</p><p>The researchers are also developing more sophisticated models that mimic the behavior of swirlonic animals such as starlings, fish, and insects. In these models, the active particles will have information-processing capabilities that allow them to make movement decisions as living creatures presumably do. They hope these models will reveal some of the secrets behind flocking, schooling, and swarming.</p><p>Another future possibility is creating man-made active particles that can self-assemble. Other Leicester experts agree that this is reason alone to continue researching swirlons.</p><p>In any event, say study co-author <a href="https://www2.le.ac.uk/departments/mathematics/extranet/staff-material/staff-profiles/it37" target="_blank">Ivan Tyukin</a>, "It is always exciting to consider deepening our understanding of novel phenomena and their guiding physical principles. What we know to date is so much less than what there is to know. The phenomenon of the 'swirlon' is part of the tip of the iceberg of hidden knowledge. It leaves us with the eternal question: 'what else don't we know'?"</p>
One bill hopes to repeal the crime of selling sex and expand social services; the other would legalize the entire sex trade.
The Equality Model asks, criminal or victim?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTcwMzY3OS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxOTUxNjE3M30.g5Ln46h9dqAFsymzKPhZ22-euuhjzAqLcreFKC2oOn0/img.jpg?width=1245&coordinates=0%2C896%2C0%2C-1&height=700" id="06827" class="rm-shortcode" data-rm-shortcode-id="ef934a819b529e8ec5ba6412bf332cfb" data-rm-shortcode-name="rebelmouse-image" data-width="1245" data-height="700" />

(Photo: Timothy A. Clary/Getty Images)<p>The most recent of the two is the Sex Trade Survivors Justice & Equality Act. Set to be introduced by Senator Liz Krueger of Manhattan, the law would repeal the crime of prostitution in the state but would maintain punitive measures against buyers and pimps. The penalty for buying sex, for example, would be a sliding-scale fine based on income.<strong> </strong>The bill also aims to strengthen laws against trafficking and eliminate the so-called <a href="http://ypdcrime.com/penal.law/article230.htm#p230.03" target="_blank">ignorance defense</a>, which affords buyers legal cover if they did not have "reasonable grounds" to assume their victim was underage.</p><p>The Sex Trade Survivors Justice & Equality Act is based on <a href="https://www.equalitymodelus.org/why-the-equality-model/" target="_blank">the Equality Model</a>, first introduced in Sweden in 1999. Under the Swedish Sex Purchase Act, the country decriminalized prostitution and began targeting buyers and suppliers with the goal of lowering demand. As demand decreased, the thinking went, Sweden would witness a subsequent reduction in violence, trafficking, and the trauma associated so strongly with the illicit sex trade. And <a href="https://www.government.se/4a4908/contentassets/8f0c2ccaa84e455f8bd2b7e9c557ff3e/english-summary-of-sou-2010-49.pdf" target="_blank" rel="noopener noreferrer">a 2008 report</a> did find that the strategy manifested some of those goals. </p><p>After the law's introduction, costs increased, fewer men sought to purchase sex, and the number of women in street prostitution halved—though the burgeoning internet scene likely influenced that metric as much as the law. </p><p>As for Sweden's prostituted population, the report was mixed. Fears of the law driving prostitution further underground weren't realized, nor did the risks of physical abuse or dangerous living conditions increase. However, while people who sought to leave the life favored the law, those who wished to stay in the trade denigrated it for hyping the social stigma. </p><p>After the report's release, countries such as Norway, Iceland, Canada, and Israel adopted the Equality Model, and today, many U.S. advocacy groups champion for states to institute similar laws.</p><p>"We who have been in the human-trafficking policy movement for a long time have been advocating for years that people in prostitution should not be criminalized for their exploitation," Alexi Meyers, director of anti-trafficking policy at <a href="https://sanctuaryforfamilies.org/" target="_blank" rel="noopener noreferrer">Sanctuary for Families</a>, told us in an interview discussing the New York bill. "It's the only law where the victim is arrested. Instead of handcuffs, [people in prostitution] need services, need housing, need support."</p><p>Critically, the Sex Trade Survivors Justice & Equality Act does more than decriminalize prostitution. It also bolsters social services such as housing, job training, and mental health care. To help finance these services, money collected by the aforementioned buyer fine will go into a victim-compensation fund. The bill also expands protections for minors arrested under safe harbor and would vacate victims' prior convictions so they could more easily find jobs. </p><p>"When someone has had no family support, have been abused their entire lives, and they haven't gotten the services they need, at the age of 18, they haven't magically transformed from a victim of trafficking into a prostitute," Jayne Bigelsen, vice president of advocacy for Covenant House, New York, said in our interview.</p><p>Bigelsen grants that while not everyone engaged in the commercial sex trade may view themselves as a victim, but she notes that a large portion of the population remains vulnerable nonetheless. To treat such people as criminals, as so many contemporary laws do, does no one any favors. The fear of arrest <a href="http://www.prostitutionresearch.com/pdf/Prostitutionin9Countries.pdf" target="_blank" rel="noopener noreferrer">actively discourages</a> victims from seeking an "off-ramp" to the life and strengthens the coercive hold their pimps and traffickers maintain on them.</p><p>"[The law helps] reframe the understanding that this is not a crime. It is a form of gender-based violence and exploitation. I think, over time, people will have a greater understanding of that," Bigelsen adds.</p>
Prostitution, an occupation like any other?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTcwMzY1My9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY2MTc3NjkzNX0.M_8OftwQ5yaGs4YyUPLIRNUAU7Ip-np2cNNdtEl8gLE/img.jpg?width=1245&coordinates=0%2C565%2C0%2C5&height=700" id="0b146" class="rm-shortcode" data-rm-shortcode-id="6027492cc1cb2a2168dc65154aed7845" data-rm-shortcode-name="rebelmouse-image" data-width="1245" data-height="700" />

Worse, they argue, it further stigmatizes sex workers within society and drives the sex trade further underground, where exploitation and violence can continue to fester from prying eyes.</p><p><a href="https://www.nysenate.gov/legislation/bills/2019/s6419#:~:text=S6419%20(ACTIVE)%20%2D%20Sponsor%20Memo&text=Part%20B%20repeals%20and%20amends,are%20repealed%20under%20this%20bill." target="_blank">A second New York Senate bill</a>, currently in committee, would decriminalize the entire sex trade within the state. Called the Stop Violence in the Sex Trades Act, the bill would keep penal laws related to minors and sex trafficking but would make sex work between consenting adults a legal, regulated trade.</p><p>"Sex work is work and should not be criminalized by the state," Senator Julia Salazar, who introduced the bill, stated in <a href="https://www.decrimny.org/post/for-immediate-release-decrim-ny-legislators-intro-first-statewide-bill-to-decriminalize-sex-work" target="_blank" rel="noopener noreferrer">a press release</a>. "Our current policies only empower traffickers and others who benefit from keeping sex work in the shadows. New York State needs to listen to sex workers and make these common-sense reforms to keep sex workers safe and empower sex workers in their workplaces."</p><p>Like the Sex Trade Survivors Justice & Equality Act, Salazar's bill draws inspiration from European laws, namely those from the Netherlands and Germany. Both countries legalized the sex trade a few years after Sweden introduced its Equality Model—though laws and regulations vary between the countries and even districts within them. For example, <a href="https://www.dw.com/en/germany-introduces-unpopular-prostitution-law/a-39511761" target="_blank" rel="noopener noreferrer">Germany has passed a law</a> that requires any business offering sex services to apply for a permit "that will only be granted if health, hygiene and room requirements are met," while <a href="https://www.amsterdam.nl/en/policy/policy-health-care/policy-prostitution/#:~:text=In%20Amsterdam%2C%20prostitution%20in%20private,supplying%20locations%20for%20illegal%20prostitution." target="_blank" rel="noopener noreferrer">Amsterdam limits</a> window prostitution to specific city zones.</p><p>Full-decriminalization advocates hope such laws will facilitate freedom of choice, access to social services, improved health and working conditions, and the decoupling of the occupation from criminal enterprises. They also argue that full decriminalization closes the unintended consequences created by the Equality Model.</p><p>An <a href="https://www.amnesty.org/en/latest/news/2016/05/amnesty-international-publishes-policy-and-research-on-protection-of-sex-workers-rights/" target="_blank" rel="noopener noreferrer">Amnesty International</a> report notes that in Norway, sex workers are routinely evicted from their homes because landlords fear rental agreements will expose them to prosecution for promoting sex. Similar liability concerns deter third parties, such as security, from working with sex workers, too. As a result, sex workers themselves may not be prosecuted but their lives are no less secure nor more firmly established within society.</p><p>"What we have isn't working. The current model of criminalizing sex work traps sex workers and trafficking survivors in cycles of violence. The new proposed legislation referred to as the 'Equality Model' conflates sex work with sex trafficking, using the logic of broken windows policing to address trafficking by targeting sex workers," <a href="https://www.decrimny.org/post/the-equality-model-is-criminalization-by-another-name-pass-the-stop-violence-in-the-sex-trades-act" target="_blank" rel="noopener noreferrer">writes the advocacy group Decrim NY</a>.</p>
New York State to lead decriminalization<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="28c828b962f38fcf2605aa8ed21553e4"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/jMji-YE1qVA?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Of course, Equality Model advocates have their arguments against full decriminalization. Even in countries that have legalized prostitution, the sex trade retains <a href="https://www.bbc.com/news/world-europe-46919294" target="_blank">strong ties to criminal activities</a>. Prostituted women continue to be viewed as pariah—or, in the case of Amsterdam, tourist attractions. And like the legal sex trades of the ancient world, contemporary examples have witnessed a surge in human trafficking to meet the demand. More often than not, poor women from poor countries.</p><p>"If you decriminalize people who buy sex, you're removing any legal barriers or social barriers, and the number of people who buy sex will exponentially increase, and you'll have to fill that new, legal demand with supply. And that supply is human bodies, and there aren't enough willing participants to fulfill that need. That's when trafficking occurs," Alexi Myers told us.</p><p><a href="https://ec.europa.eu/anti-trafficking/sites/antitrafficking/files/federal_government_report_of_the_impact_of_the_act_regulating_the_legal_situation_of_prostitutes_2007_en_1.pdf" target="_blank">A report commissioned</a> by Germany's Federal Ministry for Family Affairs, Senior Citizens, Women and Youth looked into the effects of the country's 2001 law. It found the intended impacts to be lacking. According to the report, the Prostitution Act did not create measurable improvements on social protection, working conditions, reduced crime, or the means for leaving the business. The report did assuage some fears, however, by finding that legalization did not make it more difficult to prosecute sex traffickers or related violence when they occurred.</p><p>All told, data will never point to a perfect solution to this or any social concern. In the case of prostitution, emotions and moral instinct run at the redline. Often, the solution one proposes comes down to one's answer of this question: What is prostitution? Is it a violation of another human's rights and dignity? An occupation like any other? Or a moral offense old as the law itself? </p><p>Whatever your answer, you'll likely find current U.S. law lacking. It's for this reason that <a href="https://www.governing.com/archive/more-states-separate-prostitution-sex-trafficking.html" target="_blank" rel="noopener noreferrer">many states are reanalyzing and revamping their prostitution laws</a> to protect victims, usually with more robust safe harbor laws. Whichever law New York State chooses, its successes and failures will likely serve as a bellwether for the United States moving forward.</p>
And if they could, would they care? asks philosopher John Gray in his new book.
- In Feline Philosophy, philosopher John Gray argues that self-awareness isn't the epitome of evolution—and it leads to suffering.
- Gray investigates Pascal, Spinoza, and Lao Tzu to understand why humans are so uncomfortable with themselves.
- Whether or not humans aspire to become like cats, Gray says nature teaches us the lessons felines inherently know.
John Gray: Cats, Humans and the Good Life<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="f867f099313c71c325aeb006a2aaee4a"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/er_TwUbvpmI?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Cats, like humans and all other animals, do have goals: food, sex, shelter. Certainly not existential distress. Gray notes that the technological fervor dreamed up by transhumanists in their quest for disembodied consciousness is nothing more than a Theosophical fever dream. We haven't really traveled as far forward as our self-appointed credit pretends. </p><p>Humans are not designed to understand the complexities of the universe, nor even of our own biology. Even the notion of morality, as often marketed by religious traditions, is a farce, since people are only really "expressing their emotions." The only recourse we have for discussing emotions—physiological changes that disrupt homeostasis and warrant explanation—is language, and language is a powerful but limited mechanism for discussing reality. </p><p>And what is reality again? </p><p>She turns onto her back to expose her belly to the sunlight. </p><p>Metacognition, often championed as the great divine upgrade elevating humans above the pack (instead of, say, opposable thumbs, group fitness, or an incomprehensible ability to inflict violence), is actually the "chief obstacles to a good life," as Taoists phrase it. </p><p>Gray leans heavily on a number of thinkers—Aristotle, Hume—but the minds of Pascal and Spinoza prove most feline. Pascal knew sitting silently in a room is harrowing—pre-smartphone! We need diversions, he knew, endless entertainment and amusements to distract a mind as uncomfortably matched to its environment as our own. </p><p>Spinoza is the most Taoist of Western thinkers. Gray finds solidarity between Lao Tzu and ol' Benedict in the latter's notion of <em>conatus</em>, "the tendency of living things to preserve and enhance their activity in the world." Sadly, our enhancements cost the weight of the world. Despite what we believe, other animals don't aim to become more human-like, nor did evolution finalize its process with us. Other species have little problem becoming what they are. That's a uniquely human deficiency. </p><p>Humans, Gray writes, find actual fulfillment by applying a "Spinozist-Taoist ethic." We <em>can</em> actually be happy by being ourselves. </p><p style="margin-left: 20px;">"A good life is not shaped by their feelings. Their feelings are shaped by how well they have realized their nature." </p>
Photo: ViRusian / Adobe Stock<p>In the end, we become like cats thanks to an indifferent world. Only humans invent stories that reflect reality not whatsoever. Our brains chronically fill in knowledge gaps; those gaps often offer incorrect assessments. Existence is conditional to our environment regardless of how we try to manipulate it in our favor. You can only exploit nature for so long before she grows bored or angered by our tinkering—but there we go assigning human traits to a process that will never play by our rules. </p><p>This the cat knows—by not knowing, or caring, at all. </p><p>Despite the persistent myth, cats display affection; they can learn to love their human roommates. Do our three cats climb into bed with my wife and me every night out of comfort or simply to keep warm? Irrelevant. Humans are conditional animals too. At least cats don't confuse pragmatism with emotion. They're content with what comes. We are not.</p><p style="margin-left: 20px;">"If cats could understand the human search for meaning they would purr with delight at its absurdity. Life as the cat they happen to be is meaning enough for them. Humans, on the other hand, cannot help looking for meaning beyond their lives." </p><p>Gray offers a prescription for our duress. His ten feline commandments are ultimately for us; cats would use the pages for litter if given the opportunity. Consider the following three cliff notes for the anxious animals that we are. The irony: to achieve them you need to stop trying to achieve them—another paradox cats have no issue embodying. </p><ul><li>Do not become attached to your suffering, and avoid those who do.</li><li>Forget about pursuing happiness, and you may find it.</li><li>Beware anyone who offers to make you happy.</li></ul><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a> and <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank" rel="noopener noreferrer">Facebook</a>.
