Chris Hemsworth Gets Unexpectedly Deep with Theo Von

Chris Hemsworth on This Past Weekend with Theo Von, Episode 640. Runtime: 99 minutes. Published February 17, 2026.

Chris Hemsworth just casually revealed he carries two copies of the APOE4 gene, the worst possible genetic hand for Alzheimers, a combination found in roughly one in a thousand people. He found out on camera while filming his longevity show Limitless, then had to tell his father, who five years later was diagnosed with the disease himself. What started as a TV show about extreme physical challenges became a love letter to a man slowly losing his memory.

Three things from this conversation that will change how you think about fame, mortality, and what actually keeps humans alive past 100.

The Alzheimers Bombshell That Changed Everything

Hemsworth discovered his genetic predisposition to Alzheimers during bloodwork for his Disney Plus show Limitless. Both parents gave him the worst possible copy of the APOE4 gene. He sat his dad down and said dont worry, its not a death sentence, its a warning sign. His father Craig replied oh dont worry mate, well figure it out. Five years later, Craig was diagnosed with the disease.

What followed was a deeply personal episode called A Road Trip to Remember, built around reminiscence therapy, where you revisit your past to stimulate the hippocampus, the exact part of the brain dementia attacks. Hemsworth admits he went in hoping for a silver bullet cure and instead got something more profound. It became a love letter to his father. The conversations they had on camera, about fears, about the disease, about what it means to slowly lose yourself, were things Hemsworth says he never would have asked otherwise.

His father had started to feel like a burden, like he was just a patient. The show gave him agency. It gave him purpose. They went back to the Aboriginal community in the Northern Territory where Chris grew up, where the locals called Craig a Chuck Norris looking guy because he used to pull cattle down by their tails and tie them up with his long ponytail flying behind him. Before the cattle work, Craig spent most of his career in child protection, going into homes to assess neglect and abuse, presenting evidence to courts, working with police to determine if children were safe. Chris watched the toll that work took on his father over decades, solving one case only to find a pile of new ones on the desk the next morning.

The stress connection is devastating. Chris describes watching his fathers memory deteriorate in real time when stress spikes. Craig went to put petrol in his motorbike, it wouldnt start, his wife picked him up, he went back with the spare key, it still wouldnt start, and he did this three times in one day. By the time Chris arrived, Craig had forgotten the bike existed in the ten minutes between putting it on the back of the truck and arriving home. But the next day, once the problem was solved and the stress dissipated, he was better. The disease feeds on cortisol. The bad kind of stress, the frustration of losing your keys and beating yourself up about it, that is what accelerates the decline. The good stress, like exercise or crossword puzzles, actually helps.

Compared to other family members and people in their community who received the same diagnosis around the same time and progressed to a catatonic state, Craig is doing remarkably well. He could sit in the room and have a conversation. It is the short-term memories that go first, and the wrong kind of stress that makes it visibly worse.

The Blue Zones Secret Nobody Follows

The most important takeaway Hemsworth pulled from two seasons of Limitless wasnt cold plunges, fasting, or strength training. It was social connection. The regions where people consistently live past 100, known as blue zones, all share the same pattern: multigenerational living, strong friendships, daily natural movement like walking and gardening, and a clear sense of purpose.

The blue zones are Okinawa Japan, Ikaria Greece, Sardinia Italy, the Nicoya Peninsula in Costa Rica, and Loma Linda California. Despite wildly different cultures, diets, and climates, they all converge on the same fundamentals. Natural movement built into daily routines, not gym sessions. Plant-heavy diets high in vegetables, beans, and whole grains. Low chronic stress. Light or no alcohol. Multigenerational households. And above all, a community that needs you.

Hemsworth has restructured his own life around this. He worked to bring his entire family closer together geographically, reversing the modern trend of isolated nuclear households where you dont even know your neighbors. He points out that our grandparents generation often smoked, drank, and ate steak and eggs daily, yet many lived into their 90s, because they had huge households, shared responsibility, and community. The centenarians who live past 100 arent retired. They still work, whether thats maintaining a garden, helping with grandchildren, planning trips, or contributing to their community. Purpose doesnt mean a corner office. It means having a reason to get up.

Theo Von adds a recovery perspective. In his twelve step communities, they say connection is the opposite of addiction. Being in a room where someone articulates the exact thought youve been carrying but couldnt put into words, that is therapeutic in a way no pill can replicate. He describes his morning Zoom meetings where guys share whats going on in their lives, and some of them say things Theo always wanted to say but couldnt make the words for. That validation, that feeling of being understood, is the foundation of recovery.

Theos mother, in her 70s, still delivers packages for Amazon and Whole Foods, not because she needs the money, but because sitting in the lot waiting for her next route gives her purpose. Theo pictures her in her van, waiting to deliver a catalytic converter to some guy across town, and he loves it. She is alive because she has something to do tomorrow.

The data on stress is brutal in its simplicity. Hemsworth makes the point that the amount of stress involved in pursuing perfection, in being the person who never eats sugar, trains seven days a week, and obsesses over every variable, that stress itself is more dangerous than the things being avoided. He has had periods of extreme discipline and they were not his happiest or healthiest. When a birthday cake comes, you eat the birthday cake. As Theo puts it, what are you going to be, some guy over there just sneaking a carrot out of his pocket at a kids party? The stress of smuggling that carrot and explaining it is worse than the sugar.

What Thor Thinks About at 3 AM

The most surprising part of this conversation is how philosophical Hemsworth gets. He references Carl Jung, Alan Watts, Victor Frankls Mans Search for Meaning, and a book called The Middle Passage by James Hollis about Jungian midlife psychology. This is not the interview you expect from the guy who plays Thor.

Hemsworth describes hitting a wall that most successful people eventually face. What was the goal at one point quickly becomes the norm, and then you are on to something else. The reassessment cycle accelerates. The goals he set as a young actor were achieved, and the fulfillment lasted about five minutes. Then a deeper voice started asking harder questions. Jung calls it the protest from the soul of the psyche, when the personification of self, the mask assembled from childhood through family bonds, societal expectations, religion, and community, starts wearing thin in your 30s and 40s. There is an inner protest that rises up and demands a deeper truth.

He describes the motivation behind pursuing something shifting over time. First it is purely financial, taking care of family, maintaining a position. Then that gets sorted, and a new question emerges. What is the heart actually saying? And if you are lucky enough to find something that speaks to you on a deeper level while also allowing you to function in the world, great. But Hemsworth finds himself bouncing between those questions more than ever, with more indecision and more searching than at any point in his life. The relentless confidence and pursuit he had when everything was as far out of reach as possible has given way to something more uncertain but also more honest.

He quotes Alan Watts on love. People say falling in love as if falling is the risk. You dont say rising to love. The act of falling is a surrender, and anything worth pursuing involves that surrender at some point. Being okay with the unknown, with not knowing the answer, with living in the questions rather than the answers, that is where peace actually lives.

Theo responds with his own metaphor. He says he always wants his foot on the base, something certain to stand on. But the most entertaining part of baseball is watching the guy caught between second and third while the ball gets thrown back and forth. That in between space, that uncertainty, is where the joy actually lives. As a viewer, you start to smile watching someone navigate that space. And thats life.

Hemsworth adds that there is a danger in definitives, almost a lack of humility. My voice is correct and yours is incorrect is where all problems arise. But allowing mystery, questions, and curiosity creates an abundance of opportunity to learn new things. As soon as he puts himself or other people or scenarios in a box, the world obliterates that box immediately. Living without an attachment to outcome has made him happier and more at peace with the swinging pendulum, however rapid it swings.

Victor Frankls logotherapy gets special attention. Frankl watched people in Auschwitz under identical horrific circumstances and observed why some peoples bodies gave up while others survived. Often the breaking point was learning a loved one had died. The spirit gave up and the body followed. His response was purposeful suffering, finding meaning in whatever adversity you face. This connects directly to the blue zone research. Not retiring, having a purpose, giving suffering a meaning, these are not just philosophical ideas. They are survival strategies encoded in data.

The Social Media Ban and Algorithmic Manipulation

Australia became the first country in the world to ban social media for children under 16, covering TikTok, X, Facebook, Instagram, YouTube, Snapchat, and Threads. Existing accounts were deactivated and new registrations blocked. Spain followed suit. Hemsworth is fully supportive.

The conversation takes a sharp turn into the mechanics of algorithmic manipulation. Hemsworth makes a point that the algorithm doesnt form opinions from opinions. It takes human curiosity, a single search or pause on a piece of content, and converts it into conviction. You might look at a political party out of curiosity, and within seven videos you have a biased opinion you didnt hold an hour ago. The algorithm takes you from curious to convicted.

Theo describes the experience viscerally. At 3:15 AM, scrolling X, he sees two people get shot outside a Wendys. No EMTs, no resolution, just the violence. And the next thing in his feed is a Wendys advertisement. Now hes hungry. He has forgotten the shooting entirely. The complete desensitization to something serious immediately followed by something trivial starts to deteriorate the part of you that takes serious things seriously.

The research backs this up. Large studies of more than 100,000 young adults find that each year of smartphone ownership before age 13 is associated with higher rates of depression, suicidal thoughts, aggression, and detachment. Girls show particularly large drops in emotional resilience and self-esteem. Cyberbullying follows kids home. Sleep gets disrupted. Body image comparison becomes constant.

Hemsworth notices it with his own kids. The amount of sarcastic, smart-aleck commentary they absorb from social media, the tone they adopt, comes from a complete lack of consequence. In school, if you said something awful, you felt the repercussion immediately. A fist, a social consequence, a lesson learned. Online, there is no feedback loop. You plug horrible things into comment boards with zero accountability.

Both agree there should be legal recourse against algorithms that deliberately escalate emotional responses. The algorithm is not just serving content. It is manufacturing conviction from curiosity, creating outrage for engagement, and then selling advertisements in between acts of violence. As Hemsworth puts it, the algorithm makes up your conclusion for you based on nothing more than a question you asked.

The Hitchhiking Stories and Australian Spirit

Hemsworth explains why Australians show up everywhere on the planet. Australia is so isolated that finishing high school and backpacking around the world is practically a rite of passage. About half his friends had no idea what to do after school, and they figured maybe theyd find it in Peru or wherever the backpack took them. There is an adventurous spirit born from isolation. Getting to another country is not a 2-hour train ride like in Europe. It is multiple flights, buses, trains, and boats. The journey itself becomes the point.

He missed that window entirely. He landed a soap opera called Home and Away at 18 and went straight into the working world, which eventually led to Hollywood and Thor. Now at 42 with three kids, he cant go backpacking. But there is a romanticism, a nostalgia for that period before fame, before being recognized, when you could get into trouble and explore and make mistakes without the world watching. The opportunities narrow as fame grows. Press tours take him to 10 countries, but the experience is observational from a hotel room. If there are posters of his face on the street, it becomes even more restricted.

The hitchhiking tangent is pure comedy gold. Hemsworth once picked up a hitchhiker outside Vancouver at night who started asking increasingly personal questions. Where are you from, where are you staying, what are you doing. Hemsworths immediate response was to start casually mentioning his extensive martial arts background, jiu-jitsu training, and boxing experience, essentially sizing up whether this was about to become a horror movie. Nothing happened, but the moment of mutual sizing up, neither knowing anything about the other, wondering how this story ends, that is a genuinely tense experience.

Meanwhile Mark Ruffalo, being peak Ruffalo, once picked up hitchhiking teenagers at an Australian music festival who said they were going in one direction. He didnt have the heart to tell them he was going the opposite way. He ended up on a four-hour detour, getting home at 7 AM instead of 2 AM.

They also discuss the Australian concept of schoolies, the tradition of school leavers partying after graduation, and toolies, the older people who hang around the school leavers parties. As Theo puts it, they should have a trade by that point. Pick up a hammer, do something.

Celebrity as a Mirror and Crime 101

Hemsworth describes the fundamental paradox of fame with a metaphor that sticks. You open the curtain expecting to find something magical behind it, and you realize its just a mirror. You are back in line. The assumption that achievement will void all problems is the trapping. Every industry, every demographic faces the same fundamental challenges.

His mother was a high school teacher. When Chris complained about difficult cast members and producers, she lined up perfect parallels from her own world. The students are the audience. The principal is the producer. The politics are identical. The game doesnt change with fame. New problems replace old problems, and the fundamental experience of being human remains constant.

He is promoting his new film Crime 101, a character-driven heist thriller he describes as one of the best two or three films hes been part of. Mark Ruffalo plays a detective facing police corruption. Halle Berry plays an insurance broker battling ageism. Hemsworth plays a jewelry thief at a moral crossroads, a man from foster homes who lives by a strict code of nonviolent robbery but is seeking an exit from the criminal world through one final heist. Its a homage to 70s, 80s, and 90s heist films where emotional intensity matches the action sequences.

Hemsworth connected deeply to the character because of the backstory of broken homes and the search for connection in all the wrong places. He researched men in the criminal world who came from foster care and fractured families, seeking the brotherhood and safety they never had. Its the same theme running through the entire conversation: purpose, connection, and the consequences of their absence.

Key Takeaways

One. Social connection and purpose are the strongest predictors of longevity, more powerful than any diet, supplement, or exercise routine. Five blue zones across different cultures all converge on the same truth.

Two. Hemsworths APOE4 discovery and his fathers Alzheimers diagnosis transformed his understanding of what matters. Stress is the accelerant. Community is the antidote.

Three. Success does not solve existential questions. Hemsworth, one of the most recognized actors on earth, is deep in Jungian psychology navigating the same midlife questions everyone faces. The mask cracks in your 30s and 40s.

Four. Australias social media ban for under 16s is a global first. Algorithms dont just serve content. They manufacture conviction from curiosity and sell advertisements between acts of violence.

Five. Living in questions rather than answers is not weakness. Its courage. Eat the birthday cake. The stress of perfection will kill you faster than the sugar.
