Dr. Robert Sapolsky: Science of Stress, Testosterone & Free Will

In this episode, I interview Dr. Robert Sapolsky, Ph.D., Professor of Biology, Neurology & Neurosurgery at Stanford University. We discuss stress, what defines short-term versus long-term stress, and how stress can be beneficial or detrimental, depending on the context. We also discuss stress mitigation and how our sense of control over stress mitigation techniques, including exercise, determine health outcomes. Dr. Sapolsky explains some of the key effects of the hormone testosterone - how it can amplify pre-existing tendencies for aggression or sexual behavior, but that it does not produce those behaviors per se. He also explains how testosterone impacts our social hierarchies, sense of confidence, and willingness to embrace challenges of different kinds. He also explains how our behaviors and perceptions shape testosterone levels. And we discuss estrogen and the powerful role it plays in brain development, health and longevity. Finally, we discuss free will, what it means to have free will, and if we have any free will, including how knowledge alone might allow us to make better decisions for ourselves and society.

So the least corrupt countries who held their citizens hostage for the shortest amount of time had the lowest Boogey Virus rates. Of course.... because people don’t get sick from germs, they get sick from being scared and upset about something that happened in their lives. Enter the worldwide FEAR CAMPAIGN brought to you by governments who have lied for decades. Governments who allow synthetic foods on the market like fake butter, Twinkies, telling you to eat 10 servings of toxic grains a day in order to keep your heart healthy, meanwhile it's causing everyone to become diabetic....THIS is who you take health info from??! Governments that lied about the medical benefit of marijuana are now to be TRUSTED? The Germ Theory was never actually proven to be 100% accurate, yet the trillion dollar medical industry is entirely based on that theory. What's the CAUSE of death in people with this "virus"? Does their brain explode? Does their heart stop beating? The CAUSE of death is still pneumonia. Pneumonia is not something you can "catch". It's a biological result of being "scared to death" of something which is exactly what the media has done to people dumb enough to watch them. You've heard the term "Worried sick". That's because your BRAIN causes you to become sick due to the stress it is perceiving! Why do you think young kids aren't getting the Boogey Virus? Because they aren't sitting in front of the news being scared to death because they're too young to understand a Fear Campaign. These pathetic "experts" just make shit up to explain their narrative as they go. First they tell you kids bring home every illness from school because they're not "exposed" to enough things, then they say somehow they're immune to a Boogey Virus? Does anyone have common sense?! You don't show the symptoms of "disease" until you stop being panicked and afraid. These symptoms usually show up 1-2 weeks after you've relaxed and resolved the upsetting event. There's no such thing that some diseases you can "catch", but not all. It's not that complex! If you can't "catch" cancer, diabetes, MS, arthritis, etc., from other people, then you can't "catch" colds, flu and Boogey Viruses. So governments around the world are CAUSING fear frights in everyone based on an unproven THEORY by one man, Louis Pasteur, who redacted his claim of the germ theory on his death bed, yet no one listened. So of course, when everyone is allowed to escape the hostage situation the governments have put their people into, and they start relaxing about the Boogey Virus, that's not in any way transmissible, they will begin their healing phase (get sick), and believe they then have it, and more panic will ensue as well as martial law. The longer people allow this government to hold them hostage in their homes, the more severe the "sickness" will be. Can anyone put 2 and 2 together to figure out what I'm saying?? Western Medicine is pure fraud, and people's lives are destroyed because of it. There's no critical thinking anymore. The group thinkers are moronic and brain dead. People think they're educated because they've memorized the lies they've been told for 100 years.

I'm just one person, but I was able to beat deep longterm depression, to the extent that I got off of longterm antidepressants and am very happy and content by stopping talking about things that bother me and instead taking some time by myself and praying/meditating when I am frustrated or sad/stressed. For me NOT cementing my negative feelings through speech was a real game changer. Once my emotions were balanced, my mind became clear, and I was able to take control and make adjustments in my life that then created the changes I had wanted to see take place in my life.

Sapolsky's Stanford lecture series, available on KZbin, is legendary (in my opinion anyway). I watched it about a year ago and thoroughly enjoyed it. I only wish I could have had access to that kind of information earlier in life, but better late than never I guess.

[@marvinedwards737]

Those are great lectures. But I believe Sapolsky is making a serious error in suggesting that one must somehow be free of ones own biology in order to have free will. The whole person, including the brain and the chemical reactions required to experience their life, and to make choices as to what that whole person will do next, is not an argument against free will, but simply an explanation of how free will actually works. There is no such thing as "freedom from oneself". But there is our ability to choose for ourselves what we will do, while free of coercion and other forms of undue influence.

[@EvilMAiq]

Seconded.

[@adripekalski8148]

Thanks for the pointer! I appreciate it.

[@kjekelle96]

@@marvinedwards737 Maybe free will is like an interference pattern that randomly collapses in a changing probability-field or something.

[@marvinedwards737]

@@kjekelle96 I'm a compatibilist, so, for me, free will is a deterministic event, and freedom is a deterministic phenomenon. You see, freedom requires a world of reliable cause and effect. Without it, we could never reliably cause any effect, and would have no freedom to do anything at all. Free will is when we choose for ourselves what we will do, while free of coercion and other forms of undue influence. The act of deliberation is also deterministic, because the meaningful and relevant cause of our choice is our own purposes and reasons, our own thoughts and feelings.

Thank you for this, Dr Huberman. I feel super fortunate that I live in this era, where despite not living in the states, I got to listen to Dr Sapolsky's lectures online, and read the terrific books he had written. It was through his lectures I developed such a deep interest, and some understanding of human behaviour, which would simply not have been possible in a different era. Behave, in particular, has almost been the equivalent of a bible for me (an atheist), and even if some parts of it have been overwritten by new science, Sapolsky's structure of thinking about behaviour (1 sec before, seconds before, minutes before, hours and days before....) that combines all the different branches of science is simply unparalleled

Sapolsky - YES! One of favorite authors!

[@landscapesforlearning82]

Now I would love Sapolsky to talk with Jordan Peterson about biology and ethics. This was an excellent episode, Doc!!

[@elbowrinkles]

Not sure that Dr. Sapolsky would want to sink to that level

[@SA-ff5gc]

The more I watch you, the more I love what you are doing. Thank you

[@melissachinnici]

Dr. Sapolsky is seriously amazing. I was grateful to have stumbled upon his evolutionary biology lectures. he has radically altered my perception of reality. so much incredible insight and wisdom especially on the concept of free will.

[@SkepticalDragoon]

Simply listening to this conversation made me more happy, fufilled and willing to learn more, with a big dumb smile on my face for the entire time. Thank you.

[@MontrealCanadaa]

My favourite episode thus far and I’ve been here since day one. Dr. Sapolsky is an idol.

[@davianaorlok]

I've always been interested in behavior, but I've come to love neuroscience after watching Sapolsky's lectures on KZbin. I knew nothing about biology yet I understood and learned so much thanks to his great ability to break down complex concepts into smaller didactic pieces. This was incredibly stimulating.

[@Musiclover-uo2oi]

Some of my two absolute favourite human beings. Brilliant! Thank you so much.

Starting TRT 3 years ago was best choice ever. Finding a good doctor trained in it is important. I was depressed, tired , in constant joint and muscular pain, anxious and unmotivated before. Bloodwork showed my super low T and we fixed it. It was crazy how it helped me feel like myself again and continues to today 3-3.5 years later. Can’t stress importance of trained HRT doctors because endocrinologists just go more by the book and the books lack this research. My husband is in med school and wants to get into HRT because it is a field we feel is growing and truly helps people. And I’m sure if I went to a psychologist they would’ve just had me on antidepressants and antianxieties for the rest of my life instead which wouldn’t fix the problem and long term problems of low t. Thank you for this discussion, it needs to be spread. 👍🏻

[@Cat-zk4ke]

Hi Bethany, I’m just about to start TRT. I have the same range of symptoms that you had. How long did it take for you to see improvements? Did it alleviate all symptoms? Any side effects at all? Thank you for your feedback 🙏

[@Chhesterification]

I went to my GP and she tried to prescribe me antidepressants. I start HRT next week. It's not soon enough. My memory is effecting my career.

Just a reminder that two days ago, on April 6, 2022, Dr. Robert Sapolsky celebrated his 65th BD. For somebody who has watched our Incredibly Learned Professor giving his 25 lectures on Human biology in his Stanford Un. class walking back and forth in perpetual motion behind his long table, and continuously waving his arms to illustrate his point or draw a quick sketch on the blackboard, it was quite a surprise to listen to him literally glued to his chair, and barely getting some glimpses of him occasionally moving his arms.The new behavior is the tendency, when answering a question, of tilting his head backwards as if to pick up fresh thoughts from the air or the ceiling. The new look is a whiter, thinner beard, and a more sculpted face. This becomes even more striking in videos made the following year, 2022. Also he introduces a couple of neurobiological words I don't remember him using in the 2009-2012 Stanford lectures. What has remained unchangingly impressive is his control of the new literature he's been reading.

[@kuba5527]

Amazing ! Thank you for running this channel and all of your work !

[@anujkishor]

Words cannot convey how much I value and appreciate the ever relevant information shared in this episode.

[@winbalingit8502]

Omg!!😲 This is such a HUGE gift!!! Thank you so much for this!!! Dr. Saplosky is the one who turned me on to online education!!! I will never think or behave the same!!! My life is significantly better now!!!🙏🏽👍🏽😁❤️

[@TheGutFeels]

I havent even heard this episode and i am so excited! Really big fan of Sapolsky’s work!

[@andrejdaubner9627]

Absolute bliss to hear both of you talk about neuroscience. It is my favourite field. Wish You could invite Dr Sapolsky again.😅 Also thank You, Dr Huberman, for your work. I truly appreciate your passion You do things with.

[@KCIsMe]

Clicked on this even faster than the previous episodes. Love Prof. Sapolsky from his human behavioural biology lectures and I'm currently reading one his books! I also look forward to the more plates more dates video(s) on this video lol

[@joelpalahniuk4040]

Loved the episode, will re listen to it a couple of times. Thank you so much for your work Dr Andrew Huberman!

[@yellowdomino8965]

Are you related to chuck?

[@ashrodders]

your podcasts awesome bro i like how you drop your own knowledge without stopping your hosts flow state your a good talker and better listener its refreshing and good for the brain some people just wait to talk over their guest i like how you roll brother!!!

[@JaneRakali]

Sapolsky is brilliant, I always tune in to his discussions. His series of lectures at Stanford is well worth a look too.

[@spikespiegel8642]

I have attended his online lectures on Human Behavioural Biology. I am an engineering student with no relation to biology. I was still able to learn a lot from his lectures, I made some notes too. He is a great teacher, looking forward to this podcast.

[@mosesmukuna]

Never have i being so attentive, i am learning more than i did at school ,absolutely marvellous.

[@miguelg4556]

Can't believe I just found this. Glorious. Been a fan since watching his Stanford lecture series.

[@aether-elephant]

I love Robert's lectures, I have learned so, so much. Thank you so very much Dr Sapolsky.. I owe you!!

[@kiyoshuki]

I literally jumped and screamed when I saw Sapolsky in the thumbnail. There's few interviews of this incredible neurologist and I just can't believe that out of all the people Huberman is the one interviewing him in this excepcional podcast, I'm so happy I could explode. Thank you Huberman for bringing him to the podcast.

[@conniehudson4764]

Sounds like most of us had the same reaction!

[@marvinedwards737]

Sapolsky's definition of free will is a choice someone makes while "free from themselves".The biology of the person is not an external influence exercising control over the person. We cannot set ourselves in one corner of the room and set our biology in a different corner, and then claim that biology is forcing us to make choices against our will. One of those two corners is empty.

[@Iksvomid]

Jumping and screaming increases testosterone! Well done!

[@b00gi3]

Oh man, what an amazing discussion. Thank you for this presentation Dr. Huberman. Dr. Sapolsky is a global treasure. And you are a complete gem for making this youtube series, so that lay-people like myself on the other side of the world can have some access to discussions like this. Certainly beats the hell out of any conversation I can get access to in my daily life....so....thank you!

[@sebytro]

I know about Dr Sapolsky from his online course on Stanford's youtube channel, something that I listened to on and off the past years with great interest. It makes me so happy to find this interview on Andrew's channel.

[@simsammalinao1823]

Great lecture by Dr. Sapolsky. I learned very, very, very, very much. Thank you. Also the discussion with Dr. Huberman did great to the dialogue.

[@saurbach]

Thoroughly enjoyed watching both of you on KZbin. I would love to learn more about the stress response and personal trauma, aside from what I already know. I spent the end of 2019-2020 caring for my father that was previously a DDS, but was diagnosed with a gliablastoma. I identified with the part where he discussed control/stress regarding my father’s illness.

[@paulofernandes1375]

So glad you have Dr Sapolsky on your show! But 1h30m seems just to short of a podcast with him ahah I really hope you bring him back some other time.

[@gregceth443]

Simply brilliant, so much respect for this man

[@user-oj9sv4vx6o]

I have been a Sapolsky fan for many years but hadn't seen this great discussion. Huberman's deeply knowledgeable and intelligent contribution brought out the best in Sapolsky.
