Summary: Most people have seen cool medical imaging devices such as CT and MRI scanners on TV shows. But what do those machines really do? Advanced medical imaging has revolutionized patient care in the past 25 years, allowing doctors to make diagnoses more accurately, quickly, and safely than ever before. Radiologist Paul Hsieh will discuss the basics of modern radiology (x-rays, MRI, ultrasound, and nuclear medicine), how these different tests work, what they show about the human body, and how they help doctors take better care of patients.
Question: Are the moral arguments for veganism (and vegetarianism) rational? People often argue for vegetarianism on the grounds that a person can (and perhaps should) regard the lives of animals to be a higher value than the advantages to eating meat such as taste or nutrition. Is this a rational moral outlook, consistent with rational egoism?
Question: Should the government mandate vaccination? Advocates of free markets often disagree about whether vaccines are safe, effective, and necessary – and whether they could be justly mandated by law. One problem is that the refusal to vaccinate oneself might put others at risk. Not everyone can be vaccinated, and some people who are vaccinated don't develop immunity. However, when the vast majority of people are vaccinated, that provides "herd immunity" to people who don't have immunity. People who choose not to be vaccinated degrade that herd immunity and thereby put others at risk. Moreover, parents have to choose whether to vaccinate their children or not, and the failure to vaccinate is regarded as neglect by many people – on par with Christian Science parents refusing to give a sick child antibiotics. Given that, should vaccinations be mandated by the government? If so, under what circumstances? Or might people be held civilly liable for transmitting diseases? Or should vaccination be considered a purely private matter between individuals (and institutions)?
Summary: The practice of emergency medicine is heavily regulated by the government. What is EMTALA? What are its effects? What have the effects of ObamaCare been so far? How do these laws compromise patient care and make the practice of medicine more difficult? How could emergency medicine be made more free?
Question: What should I do when a friend exhibits severe body dysmorphia on social media? At several points in my life, I had a valued friend who seemed otherwise rational and grounded, but who also exhibited dangerous body dysmorphia on social media. In these cases, the friend would first go through a several-month phase of confessing to several psychological problems, such as fantasizing about suicide and of cutting herself with a blade. This friend would then sternly add that she has since recovered, but would admit to still feeling that her natural physical features are ugly and deformed. Then, months later, the friend would go into another phase. On social media, in front of many other people, she would make brazen gestures indicating body dysmorphia, such as uploading photoshopped pictures of herself as a corpse ready for burial or saying that she planned to starve herself to achieve her ideal of being skeletally thin. A major problem was the reaction from our online mutual acquaintances. Some admitted that they saw these problems, yet they acted like the friend was behaving normally. Others outright complimented the dysmorphic imagery and statements. In these cases, I think that my friend knew that her body dysmorphia was dangerous. She put it on display so that others would normalize her pathology, because then she could more easily rationalize her behavior as harmless. That seems really dangerous, but what is the proper alternative? How should people respond when a person puts his pathological self-destruction on display?
Question: How does a person cultivate a healthy body image? Suppose that a woman realizes that she has been unconsciously influenced by unrealistic body images – as portrayed in movies, magazines, and so on? She is basically healthy, and so it would be good for her to feel good about how she looks. But a person can't always change everything about herself: she can't change her height, however much she dislikes it. Even if a person can make changes, most people need to accept that they will never look like movie stars. So how does a person cultivate a healthy body image? How might a person notice and combat an unhealthy obsession with appearance?
Question: Is "body acceptance" rational and healthy – or dangerous? Many people are divided on the issue of accepting one's body for whatever it is. Some think that a person should be proud to be "healthy at any size" (or even just a larger-than-average size). Others say that such views perpetuate unhealthy lifestyles and destroy standards of beauty and health, perhaps out of envy. What is a rational view of body acceptance? Is "fat shaming" or "fit shaming" ever acceptable? More generally, what are the boundaries of morally acceptable comments on such matters between acquaintances, friends, and strangers?
Question: Is it wrong to walk away from a person who suffers from repeated medical emergencies due to their own irresponsibility? Over a year ago, I was the tenant of a type-1 diabetic who refused to eat properly. As a result, I regularly had to call the ambulance for her, as she would allow her blood-sugar to drop to dangerous levels, such that she couldn't think or move for herself. She never learned anything from these experiences. She never put emergency food within reach, for example. So a few days or weeks later, I would have to call the ambulance again. I believe that I was being forced – literally – to take care of her. I feared that I'd face manslaughter or other criminal charges if I left her alone in that state. Would it have been morally proper for me to leave her in that state without any advance warning? Should that be legally permissible?
Question: When would suicide be rational? What conditions make suicide a proper choice? Are there situations other than a terminal illness or living in a dictatorship – such as the inability to achieve sufficient values to lead a happy life – that justify the act of suicide?
Question: How is a person's appearance related to self-esteem? Should a rational person care much about his body – including height, weight, musculature, beauty, and so on? Is that second-handed somehow? How much effort should a person exert to make himself look the way he wants to look? Should a person's looks affect his self-esteem?
Summary: Many Americans have food allergies to common foods such as peanuts, dairy, and eggs. Some of those allergies are so serious as to be life-threatening. Jenn Casey's son has a life-threatening peanut allergy, diagnosed when he was a toddler. What must people diagnosed with such allergies do to protect themselves from accidental ingestion? How can parents keep their children with such allergies safe? How should other people in their lives – such as family, friends, and teachers – do to protect them from harm? What should schools, clubs, and other organizations do? This episode is Part Two of Two. Be sure to listen to Part One.

Summary: What are some of the common ways that stress impairs a person's health? What can a person do to resolve those problems? Personal health coach Christian Wernstedt helped me recover from adrenal insufficiency, leaky gut, and other problems stemming from my 2009 crash into hypothyroidism. In this interview, he shared his basic approach and insights with us.
Question: Is it wrong for parents to have another baby to save the life of their sick child? In 1990, Marissa Ayala was born in the hope that she might be able to save her 16-year-old sister Anissa from a rare form of leukemia. (The parents went to extraordinary lengths to conceive.) Happily, Marissa was a suitable bone marrow donor, and Anissa's life was saved. At the time, many people criticized the decision as "baby farming" and treating the new baby as a "biological resupply vehicle." Yet today, the Ayalas are a close family, Anissa is alive and well, and Marissa is happy to have been born. Were the Ayalas wrong to attempt to save the life of one child by having another? What moral premises would lead a person to condemn this act?
Summary: People often think of major medical disasters as unpredictable "black swan" events. In fact, emergency physicians see the same injuries from the same causes time and again, and ordinary people can lessen those risks by their own choices. Dr. McGuff explained the risks, how to mitigate them, and how to best cope if you or a loved one lands in the emergency room.
Question: Is taking antidepressants and other prescribed drugs for mental problems a form of evasion? I'm new to the philosophy of Objectivism, and I've seen that it's rapidly helping cure the last parts of a depression I went through last year. I started taking Adderal about eight months ago, and it has helped tremendously. But I wonder: Does taking these drugs or other antidepressants conflict with the principle that a person should never evade reality?
Question: Is mental illness nothing more than a myth? It seems that many members of the free-market movement are enthused about the theory, promulgated by the likes of Thomas Szasz and Jeffrey A. Schaler, that there is no such thing as mental illness. They say that if one cannot pinpoint a direct physiological cause for behavior considered "mentally ill," there are no grounds for referring to that behavior as a symptom of some "illness." Furthermore, they argue that the concept of "mental illness" is simply a term that the social establishment uses to stigmatize nonconformist behavior of which it does not approve. Is there anything to these claims? If not, what's the proper understanding of the basic nature of mental illness?
Question: Should minor girls be required by law to obtain parental consent for an abortion? Normally, parents are legally empowered to make medical decisions for their minor children, and minors cannot obtain medical procedures without parental consent. How should that apply in the case of pregnancy? Should pregnancy and abortion be treated differently from other medical conditions? Should parents be allowed by law to force a daughter under 18 to carry a pregnancy to term or to abort against her will?
Question: Is it right or wrong to condemn people for being obese? Obviously, obese and morbidly obese people have made mistakes in their lives. Are they morally culpable for those mistakes? How should other people judge their characters? If I see an obese person on the street, should I infer that he is lazy and unmotivated? Should I refuse to hire an obese person because I suspect he won't work as hard as a non-obese person? Is obesity a moral failing – or are there other considerations?
Question: Why is consensual incest between adults morally wrong? In late 2010, David Epstein, a professor of political science at Columbia University, was charged with incest for a consensual sexual relationship with his adult daughter. That case raised uncomfortable questions about the morality and legality of consensual incest. What constitutes incest? Why is it wrong? Should it be outlawed?
Summary: What is the paleo diet? How can athletes and others benefit from it? What kind of training and nutrition is required for endurance competition? What's wrong with the standard methods of training and nutrition for athletes?
Question: How would antibiotic resistance be handled in a free society? Bacteria acquire resistance to antibiotics by exposure to low doses of antibiotics. Such low doses may come from misuse of antibiotics, for example when taken to combat a cold or flu (which are viral infection against which antibiotics do nothing) or by not completing the full course as prescribed by a doctor. Antibiotics are indeed awesome drugs which have saved millions of lives. But resistant bacteria pose a serious health problem, often causing serious and difficult-to-treat illness in third parties. What would be the proper way to address this problem in a free society?
Summary: The government heavily regulates food and drinks commonly regarded as dangerous or unhealthy. What motivates such regulations? Why are they so widespread? How can they be fought?
Summary: Most people suppose that fitness requires long "cardio" sessions of running, biking, stair-climbing, or the like. In contrast, Dr. Doug McGuff advocates brief, infrequent, and high-intensity weight training using slow movements. Does this approach work? What are its benefits and costs compared to other fitness regimens?
Summary: Many people struggle with difficult decisions about complex medical problems as they near the end of their lives. That time is wrenching for family too. How can people make good decisions about medical care? What mistakes should they try to avoid? How can people prepare for that future now?
Question: Should it be considered child abuse to feed a child a vegan diet? Most experts agree that children need some of the nutrients found in meat and dairy products to develop properly. I've read lots of stories about children whose development is impaired or stunted due to being fed a vegan diet. Should it be considered child abuse to feed a child a strict vegan diet? If so, at which point should the state intervene and take legal recourse against the parents?
Summary: What is the paleo diet? How can it help you improve your health and look better? Why does it work?
Question: How would the government protect the safety of food and drugs in a free society? Would the FDA (Food and Drug Administration) exist in free society? If so, would food or drugs have to gain FDA approval to be sold? Would it have the power to remove food or drugs deemed unsafe from the market? If not, what would protect consumers from harm due to adulterated or otherwise unsafe food or drugs?
Question: Should people with severe genetic diseases take active measures to prevent passing the disease to their children? Some people have severe hereditary diseases – such as Huntington's or Multiple Sclerosis – that might be passed on to their biological children. If that happens, the child will be burdened with the disease later in life, perhaps suffering for years and dying young. Is it wrong for such people to conceive and merely hope for the best – rather than screening for the disease (and aborting if necessary), using donor eggs or sperm, or adopting? Are the parents who just hope for the best harming their future child? Are they violating their child's rights by refusing to take advantage of available technology for preventing the disease?
Summary: With ObamaCare confirmed by the Supreme Court, what can a person do to preserve his health under America's increasingly socialized system of medical care?
Question: Is it moral to smoke, drink, or eat unhealthy foods if one recognizes the costs of doing so? Suppose a friend makes a deliberate decision to eat foods he know to be unhealthy (such as frequent sugary desserts). He knows that it might harm his health, but he says that the personal enjoyment and satisfaction outweigh the risk of shortened lifespan and possible future harmful health effects. In other words, he claims he is making a rational choice to maximize his overall happiness. Is that moral?
Question: What should we do if the Supreme Court upholds ObamaCare? The Supreme Court of the United States will be determining the constitutionality of ObamaCare in a matter of weeks. While it is likely that at least part of it will be struck down, the court might uphold some or all of it. If that happens, what should liberty-loving Americans do? Would we have any recourse? Would it be time to break out the pitchforks and torches?
Question: How can I stop my spouse from sabotaging my self-improvement? Over the course of my 15 years of marriage, I'd gained over 100 pounds. After feeling disgusted with myself for too long, I decided to change my habits. So I switched to a paleo-type diet and started lifting weights. So far, I've lost 40 pounds, as well as shed some health problems. My husband still eats what he pleases, and I don't pester him about that, although he needs to eat better too. However, he's constantly attempting to undermine my efforts – for example, by bringing home and encouraging me to eat doughnuts. I want him to celebrate and support my new-found success, but he seems to want me to be fat, unhealthy, and miserable. What should I do?
Question: Is it wrong to stockpile medication now in the event of an economic crash in the future? We are concerned that increasing economic troubles will raise the prices of some prescription and over-the-counter medications, and make them hard to find in the future. Is it okay to start a stockpile of some medications (most of which have a long shelf-life)? In the case of prescription medications, is it okay to exaggerate to our doctors or play "musical pharmacies" in order to obtain more medication?
Question: Is overfeeding a child a form of abuse? In November, county officials in Ohio placed a third-grade child into foster care on the grounds that he's over 200 pounds and his mother isn't doing enough to control his weight. (See the news story.) The boy does not currently have any serious medical problems: he's merely at risk for developing diabetes, hypertension, etc. The county worked with the mother for a year before removing the child, and it claims that her actions constitute medical neglect. Now his mother is only permitted to see him once per week for two hours. Did the state overreach its proper authority in removing the child from his home?
Question: Is it immoral to give away food that you regard as unhealthy? Assuming that one believes (as I do) that candy and sweets are harmful to health (especially in quantity), is it immoral to participate in trick-or-treat by giving children candy when they come to your door? Or, is it immoral to "dispose" of an unwanted gift of, say, a rich chocolate cake by leaving it by the coffee machine at work to be quickly scarfed up by one's co-workers (as an alternative to simply discarding it)? Is the morality of these two cases different because in one case the recipients are children while in the other case they are adults?
Question: What's the proper view of using cryonics as a means of extending one's life? Suppose there is at least a small chance that, if I am cryonically frozen in the coming years, doctors will be able to revive me at some point in the future. And suppose that the cost is not an impediment – meaning that I don't have to give up any other important values in order to pay. Would this then be morally required because life is the standard of value? Would it be morally optional? Or is there some reason why it would be irrational?
Question: If you have a mild to moderate contagious disease, is it immoral to go about your ordinary business knowing that this will expose other people to the disease? I'm not talking about life-threatening illness here, nor am I talking about intentionally trying to get someone sick (like spitting in their food). I'm just talking about going to work, school, entertainment events, or scheduled appointments while you have an ordinary disease like a cold, flu, or strep throat. Is that moral?
Summary: On May 8, 2011, I gave a short speech at Liberty Toastmasters on my experience with hypothyroidism – and why I don't want the "cookie cutter medicine" being pushed on us by ObamaCare and other government meddling in medicine. Shortly thereafter, I made some revisions, recorded a longer version, then posted that to YouTube.
Question: Are peanut bans in schools immoral? In particular, do restrictions on certain types of food in schools (such as peanuts due to a known peanut allergy) infringe on the rights of the parents of the non-allergic kids to determine the type of diet their children follow? Are the parents of the non-allergic kids making an immoral sacrifice by following the 'no-peanut' rules? What about parents who choose to ignore the rule and send the food to school anyway? Would this scenario be any different in a private school versus a government school?
Question: Since eating wheat is purported to be unhealthy due to gluten (and other stuff), is it immoral to eat bread? (Analogous to smoking being purportedly bad for you.) Since one has to eat something, it would be better to ask, "Is eating bread immoral when other food sources are available?"
Question: Which mind-altering or mood-altering substances are rational to take? (alcohol, caffeine, marijuana, etc.) And what principles do you apply in deciding?
Question: I have a friend who is pretty hardcore paleo and is often very critical of other people's diets. Food is really important to her and I don't think she means to sound so disparaging. How do I kindly tell her to butt out of mine and my friends' eating habits?
