    Trying for a Baby? Watch This Before Your Next Drink!

    Is there any safe amount of alcohol during pregnancy? In this episode of Unknown Variables, I sit down with Dr. Alexandra Perez, PsyD, a licensed clinical psychologist and Assistant Professor at Emory University, to unpack one of the most misunderstood—and rarely discussed—topics in public health: prenatal alcohol exposure (PAE). Despite what many people hear from friends, social media, or even doctors, the science tells a more complicated story. Dr. Perez explains why no amount of alcohol has been proven safe during pregnancy, how prenatal alcohol exposure affects brain development, and why many children and adults are impacted without obvious physical signs. We explore: Why doctors sometimes say “one glass is fine” — and what the evidence actually showsWhat Fetal Alcohol Spectrum Disorders (FASD) really are (and why most cases go undiagnosed)How prenatal exposure can increase risk for ADHD, anxiety, depression, and behavioral challenges later in lifeThe role of adverse childhood experiences (ACEs) and environment — not just biologyWhy many kids are misdiagnosed when underlying neurodevelopmental differences go untestedHow Parent-Child Interaction Therapy (PCIT) helps repair parent–child relationships and reduce disruptive behaviorThe unique barriers faced by Spanish-speaking and Latine families in healthcare and researchWhy simply “translating materials into Spanish” is not enoughHow to talk about alcohol and pregnancy without shame or stigma This conversation is not about blame — it’s about education, prevention, compassion, and better systems of care. If you’re pregnant, trying to conceive, a parent, clinician, educator, or simply someone who wants to better understand how early life experiences shape mental health, this episode is for you.

    Become Financially Independent and Own Your Time with Andy Hill!

    What if the real goal of money isn’t wealth—but time? In this episode of Unknown Variables, I sit down with Andy Hill, creator of Marriage Kids and Money and author of Own Your Time, to talk about financial independence, Coast FIRE, and why so many people feel stuck even when they’re “doing everything right.” Andy shares how he and his wife went from a negative $50,000 net worth to nearly $2 million, paid off their home in under five years, and ultimately designed a life around time freedom—not just money. We talk honestly about motivation, marriage, stress, side hustles, gambling culture, index fund investing, and what it really takes to build financial independence with a family. This conversation isn’t about get-rich-quick schemes, crypto hype, or gambling apps—it’s about building margin, reclaiming your time, and designing a life you don’t want to escape from. In this episode, we cover:Why most people don’t have a money problem—they have a time problemHow motivation (not discipline) drives long-term financial changePaying off a mortgage early vs. investing: what Andy would do differentlyWhat Coast FIRE is and why it works for parentsHow to build financial independence starting from debtWhy gambling and “quick money” are destroying wealth for young peopleHow couples can get on the same page about moneyThe role of side hustles, income growth, and index fund investingWhy time—not net worth—is the ultimate measure of wealth Andy also shares the personal moments behind the numbers: marriage counseling, burnout, quitting a stable corporate job, and the realization that there are only 168 hours in a week—and how you use them matters. 📘 Andy Hill’s book, Own Your Time, is available now Learn more at 👉 https://marriagekidsandmoney.com 🎧 Listen to Andy’s podcast & YouTube channel: https://www.youtube.com/@MarriageKidsandMoney

    Rebuilding a Face, Restoring a Life

    Is the medical system broken? And what does plastic surgery really do? In this episode of the Unknown Variables Podcast, Dr. Anthony Rojas speaks with Dr. Kianna Jackson, MD, Chief Resident in Plastic & Reconstructive Surgery at Vanderbilt University, MIT graduate, and founder who challenged the residency application system itself. Most people think plastic surgery is about Botox, breast implants, or celebrity aesthetics. Dr. Jackson explains why that’s wrong—how plastic surgery is about form and function, restoring faces after trauma, burns, and cancer, and helping patients reclaim their identity when their ability to speak, smile, or be recognized has been taken from them. Dr. Jackson also shares her experience as a Black woman in surgery, confronting imposter syndrome and the “DEI hire” narrative despite graduating first in her medical school class and becoming the first Black student to win Vanderbilt’s highest academic honor. She offers a nuanced, honest discussion of affirmative action, equity vs equality, and why diversity in medicine leads to better patient outcomes. The conversation goes deeper into the broken medical training pipeline. Dr. Jackson recounts spending thousands of dollars applying to residency, uncovering a system that extracts over $100 million annually from medical students, and building CentralApp, a platform that disrupted the residency application process nationwide—forcing ERAS to lower its fees. She also shares hard-earned lessons from founding a startup while working 80-hour weeks as a surgical resident. This episode explores: What plastic surgery really is (beyond aesthetics)Facial reconstruction and restoring identityBurn, cancer, and trauma reconstructionBeing a Black woman in surgeryDEI, affirmative action, and imposter syndromeWhy residency and medical school admissions are brokenThe true cost of becoming a doctorLessons from building (and losing) a medical startupMentorship, medicine, and choosing the right path Whether you’re a premed student, medical trainee, physician, healthcare professional, or simply curious about how medicine actually works, this conversation will change how you see plastic surgery—and the system behind it. 🎧 Listen to the full episode on the Unknown Variables Podcast 🔔 Subscribe for conversations on science, medicine, entrepreneurship, and the unseen forces shaping success.

    MIT Engineer Turned Apple Insider Exposes What Americans Get Wrong About China

    What do Americans consistently misunderstand about China — its people, its politics, and how it quietly became the world’s manufacturing powerhouse? This week, I sit down with Joshua Woodward, a South Side Chicago native turned MIT mechanical engineer who spent four years inside Apple’s camera supply chain in Shenzhen before founding a manufacturing consultancy based in China. Josh didn’t just visit China — he lived through three and a half years of COVID lockdown, worked daily on factory floors, spoke fluent Mandarin to stunned locals, and built relationships inside the manufacturing ecosystem that produces the world’s most complex consumer electronics. In this conversation, he exposes: • Why America has engineering talent — but China has the ecosystem • What Americans get wrong about work culture, surveillance, and freedom • How Apple accidentally accelerated China’s tech dominance • Why tariffs don’t work and end up hurting Americans • What it’s like to be Black in China, and how language breaks barriers • Why China and the U.S. are more alike than we think Josh’s story moves from surviving Chicago, to obsessing over MIT at age 12, to becoming an Apple insider shaping devices billions of people use — and shows how much of what we assume about China collapses under firsthand experience. If you think you understand China — this episode will challenge you.
