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.

My love for neuroscience started watching Sapolsky's free lectures on youtube. Watching both of you together gives me a level of happiness that words cannot describe. Also reading Behave has made me a better human and one that's more compassionate with others (or at least that's what I try). Just thank you.
Ditto! Love RS lectures.
Same!
Me too. I discovered RS lectures 4 years ago and he rebooted my neuroscience nerdship
I’m right there, too!
I think every person in political positions should be required to read Behave. And Journalists, too.
This is the biggest neuroscience crossover episode ever
Yup, had everything. Biology, neurology, psychology, opthomology
FOR REAL
I am so hyped!!
It also had atheism
With horrible audio.
I am fangirl screaming so loud. Sapolsky is my hero! I binged his entire lecture series
Are you an atheist? I know random, But curious
100% same.
Oh his stanf lectures
Yes! He’s literally amazing and his lectures + research is amazing.
hey yo fangirl the answer is subway stops! wheres my cream cheeese bagel???!
<a href="#" class="seekto" data-time="82">1:22</a>:28 "The knowledge of the knowledge is an effector in and of itself". The absolute most powerful statement here!
Sapolsky is one of the most interesting guest this podcast could've ever have. Thrill to see this
Different guests have different personalities and scientific interests, I would not grade them....
Absolutely
Totally agree!

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.
Omg, i swallowed every single word from Prof Sapolsky' lectures on Human Behavioral Biology from 11 years ago. A pleasure to see Prof Sapolsky and Prof Huberman together here.
Me too . Old KZhead
Right! This is awesome!
Me too 😀
I have good memories of listening to his lecture videos
same!
i have rarely laughed so loudly and heartily in andrew huberman's episodes. Robert Sapolsky's humor is subtle and familiar, I love it. Laughing is my favorite way to learn
"nah"
"I'd"
I took his college class on KZhead. Saved tons of money and learned so much. He truly is a gift to humankind.
Put that on your resume. Attended Stanford University via KZhead.
I don't put my actual college courses on my resume as they are not applicable. So, seems the same @@Cuyt24 Totally possible to try and improve yourself with knowledge without any other gain.
I never realized how many people have watched Sapolsky's lectures. I too admire his work and was excited to see this. Love the genuine effort behind this channel. 👏
there's a view count at the bottom of the videos lol
It is a series that everyone should watch, the byproduct is bettering the viewer ..... |Always been recommending to friends interested in the subject.

It's remarkable that these resources are offers for free, pretty amazing
I listen to his lectures while working sometimes very much appreciate this mans existences.
i jumped out of bed like never before to run to my pc and watch this episode. SO STOKED THANKS HUBERMAN AND SAPOLSKY
Well, and I look at it now.
me too!!!!!
same! one of my favorite scientists shows up on one of my favorite podcasts
Thanks, Sapolsky is a lifetime favorite... So glad his life's dominos fell the way they did! 😉

Lmfao I love Andrew thanking him at the end and Robert being like... 'well I didn't really do anything, this was all predetermined.. but thanks"
Was laughing my ass off about the same irony :)
wow spoiler alert.
Hahaha
@@TheUltimateGC if you go through the comments, you'll have spoilers
WOW, the 20-30 mins a day for stress management blew my mind. I always feel so frantic that I will literally tell myself exactly what he says NOT to do: "I will manage this stress when the weekend comes, I am too busy and overwhelmed right now."
Sapolsky's Stanford lecture series, available on KZhead, 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.
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.
Seconded.
Thanks for the pointer! I appreciate it.
@@marvinedwards737 Maybe free will is like an interference pattern that randomly collapses in a changing probability-field or something.
@@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.
Sapolsky is an absolute scientist. Very gifted and one of the most amazing contributors to good thought of all time.
His books are great too!
For the past 13 years I have watched everything Sapolsky on KZhead and am very appreciative!
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.
Wow, that was profound! Thank you for saying that.
So you didn’t have any internal chatter of recurring negative and upsetting thoughts? That what happens to me so if anything taking time to myself I marinate in these thoughts more.
yeah cementing things internally through language is quite powerful and bad when they are counterproductive things.
@@chamade166mindful at the time that's what you're doing?
I can not believe how lucky we are to get such amazing educational resources close to free now days!! Both your podcast and Robert Sapolskys published lectures have given me an invaluable amount of insight into the biology of being human. Thankyou both for all the usefull mechanisms, explanations and potential explorations in finding our best selves, and overcoming our hardest selfs.
Close to free? Who.... who charged you to watch this?
@@kevinbissinger the collection of your data by KZhead is the exchange. Doesn't have to be monetary to be a cost.
@@kevinbissingercost of a device to listen, electric cost, internet cost
Writing my dissertation on determinism, free will, and moral responsibility, my brain lit up hearing those words during the introduction. Thank you.

Too bad none of it matters when we enter pliocene like conditions on earth in 9 years. Waste of your time Sanjay. Go learn about your future on my channel.
@@TheDoomWizard I’d argue that it matters all the more, and I dig the vids, dude!
@@TheDoomWizard Lmao yeah sure. Keep wasting your time prepping for the doomsday.
I also lit up when I heard that. 💨
Robert Sapolsky is a legend. I've read a few of his books and his passion, humor, and ability to explain things both in depth and simply in his subject are unmatched. Thank you Andrew and the Huberman Lab!
Can you explain to me what he says about Testosterone and aggression, please?
This was an absolutely brilliant episode. Hormones, ‘free will’ and the meaning of existence. Please bring Dr Robert Sapolsky back for more discussions. Knowledge of knowledge is indeed changing Thank you.
You don't believe the shivers that went through my whole body from just seeing the thumbnail with Robert Sapolski. It's crazy! Behave was one of the best books that have ever been written. Never expected him to be on the show.
+1
👍🏻👍🏻
i cant comprehend how you never expected him to be on the show, i was so sure he would appear and soon, to the point that i wasnt sure the sun is going to come out tomorrow but sapolsky will appear soon on huberman you are aware more than that sapolsky is a colleague from the same university as huberman, also that the subject matter that both are taking on is very related, and on top of this that sapolsky has given many talks which shows hes willing to appear on places to talk about science he knows so i ask again, how on earth could you say you NEVER EXPECTED HIM TO BE ON THE SHOW i have no free will but am entirely programmed to be entirely flabbergasted by your comment that is all
@@bntagkas i think he not expected around this time. It was like an unexpected reward what makes the Huberman podcast listening behavior more consistent haha
You really have to admit Sapolsky is a beautiful man. From his knowledge to his voice, from his smoothe-flowing and understandable rhetorical style to his hair and beard styles, he is remarkably beautiful.
Sounds like you're man crushing bro! Lol
@@DS-rd9qn Maybe so, maybe so...
@@defenderofwisdom Go for it dude!
Yep. I did like his hair longer. But he looks great! And I love the dog yipping in the background 🤗
@@conniehudson4764 Agreed!
This would have to be one of my favorite podcast talks ever. It just kept getting better and better. Wrapping it up with the talk about free will,,,,, mind blown. Thank you both.
Amazing, I loved Salposky's lecture series on u tube . The revelations that our behaviour is largely pre-determined is fascinating and liberating at rhe same time .
Great interview, Andrew crushed this, Sapolsky is the most amazing person alive today.
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
Same. Any other Sapolsky interviews with this quality of questions from another scientist? These videos will likely save me so much effort trying to convince friends to read a several hundred page book.
Finished binging the Huberman Lab episodes and now on to Dr Spolski's lectures. He's such a wonderful lecturer who makes complex topics intelegible for those of us with 0 science background.
I am soo much obsessed with Dr Robert spolsky, his mind blowing research, I went through his standford lecture series, being a psy student learning about physicology , neurology is amazing
Sapolsky's Stanford lecture series, on free will - super insightful! Thank you Dr. Huberman and Team. YOU ROCK!
Thank you so much for bringing Robert Sapolsky on the show. Both of you are truly inspiring science educators
Prof. Huberman, would you invite Sapolsky to talk about (his) depression? I love him and would like to know how he manages it. And why being wonderful doesn't make things better. ❤
I am extremely impressed with the level of preparedness and the seriousness with which a brilliant thinker such as Dr. Huberman approaches interviewing another brilliant thinker such as Dr. Sapolsky. It tells me a LOT about the man; his dedication to excellence, his reverence for other gifted, hard-working people, his complete lack of self-importance. This is a truly beautiful meeting of great minds and of two of my very favorite humans. Superb work!
I’ve been watching recorded lectures given by Dr. Sapolsky and it’s awesome to see him then and now - and to see him with you is a huge bonus! I love listening to his lectures I am just amazed at the volume of knowledge he communicates in a session just, nonstop, high energy, lively, and very interesting.
LOVE Sapolsky's work. What a great guy, huge contributions to the field of stress management
Thank you so much for your commitment to getting high quality information and education to the public at no cost. I greatly respect you for this.
Listened twice.. each time with curiosity and new "discoveries" Plan to listen to this awesome interview a third time... taking away new bits of knowledge.. such a richness so stimulating..
Sapolsky - YES! One of favorite authors!
Sapolsky is a KZhead O.G, thanks for having him on!
“The knowledge of knowledge is an effectuate in it of itself…” that gives me so much hope for my son. That my beautiful son is more than just the crappy genes that he might have or the toxic environment we both had to face against my stbx. My son can change as long as I keep teaching him and myself more and more. And this is all thanks to Robert Sapolsky and people like him such as Andrew. Thank you so much. This is a gift to humanity.
If you watch such content I don`t think your genes are "crappy". Dumb people don`t take interest in such topics. I think there is a high level of interest in the world and inteligence required to seek such information.
😂 blaming your stbx that you chose is a sign of profound stupidity
Keep investing in you and your son's knowledge and you will outweight your environment by soooooo much so you don't have to worry. You are a great mum, i really apreciate your thought
This was definitely the best 80 min I spent in a while, Thank you, professor Huberman and Dr. Sapolsky.
It’s 90 min
Sapolky's lectures on human behavior are life changing. Best episode ever!
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. 👍🏻
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 🙏
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.
good for you..ya insurance will also not want to pay for hormones, and blood tests are up and down 5 times a day

I love that man. It's in the struggle.He knows so much from decades of pushing through jungles, reading library's, and the life on life terms crud and he's still willing,...to keep moving.
Wish we could get more Dr. Sapolsky! This was GREAT. Just GREAT.
Dr Sapolsky's human behavioural biology lectures are phenomenal, they inspired me to learn more about the subject and think about a change of career. Dr Huberman, your work on stress mitigation, the breathing exercises you provide and a "now or never" style statement you made once on a talk somewhere have been fantastic in encouraging me to take the first steps in that direction. I'm beginning a new journey thanks to the two of you and it's great to see you both on here, brilliant episode.
I am such a fan of Dr. Sapolsky! Thank you so much for bringing him into this discussion!
Robert is amazing I have a playlist with him that I roll through once in a while.
The effects and function of testosterone is very enlightening. I have seen Dr. Sapolsky Neuroscience psychology lectures on KZhead and listen to a bit of them. From this I definitely want to listen to all of his lectures. Dr. Huberman your sponsors are very high quality and useful products
I watched many if not all of dr. Sapoloskys videos and lectures several years ago. He is also very smart and easy on the ears. It's unexpected for me that you would have him on and quite a treat. So I'll start watching this now. Thank you!
I've found a home here with this podcast. I admit I've had a troubled life but I've had so much help here. I am so looking forward to the podcast on ADHD. Thank you, Dr. Huberman!
Is estrogen better than testosterone?
@@robertdavis3788 No, nor the opposite
Hope you're staying strong. How is your progress so far?
@@francoismartineau2519 there opposite ? Don't they have specific roles?
IS Insulin better than growth Hormone? Is tnfalpha(inflamation Hormone) better than il 1 ( anti inflamation Hormone) ? Is Cortisol better than aldosterone? No they are hormones and they have important Rules in every human, and depending on age, Sex, genetic Makeup, These Levels vary... And it's important, that These hormones stay in range, generally for Testosterone one can say the higher end of the range IS preferred in men. At least that IS what Most men will say, If they manipulate their hormones( Trt) or naturally, Like good health and or Testosterone boosting Supplements. For Cortisol ITS more complicated, for Estradiol also, for tnfa or other inflamatory hormones( cytokines) they should be low in a healthy Not acutely sick individual...
Thank you I only wish we had more people like you in society explaining the human condition.
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.
Gold! Gold!! Thanks, Prof. Andrew for bringing in Dr. Sapolsky early in this podcast. Been listening to his lectures during this pandemic.
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.
Sounds like most of us had the same reaction!
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.
Jumping and screaming increases testosterone! Well done!
Dr. Robert Sapolsky was very inspiring. I'm ready to read for little. It was really nice to listen to his wisdom and knowledge. You are appreciated.
I've always been interested in behavior, but I've come to love neuroscience after watching Sapolsky's lectures on KZhead. 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.
Now I would love Sapolsky to talk with Jordan Peterson about biology and ethics. This was an excellent episode, Doc!!
Not sure that Dr. Sapolsky would want to sink to that level
Wow. If there's such a thing as a "Sapolsky fanboy," that would be me. I share his lectures from the Stanford website regularly. I truly believe that if more people listened to him, the world would be a better place. What a gift he is.
Where ?

I love the science shout outs that these guys always give to others in their field. Everytime they say something interesting they have to give a cool little shout out to the person who discovered it. While some do it excessively to appear credible, it's really nice to see when it's as genuine as these guys.
This was an outstanding interview. You asked some questions on subjects I've been researching for years. One of the best KZhead videos I've ever seen.
Incredible to be alive and able to get glimpses of such minds. Not able to express the level o joy and gratitude for your works. ❤

I've been waiting for this episode for a while now. It's amazing to have you both together.
This is such an incredible talk! So incredibly grateful to have it as reference! Thank you!
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.
Omg best crossover ever!!!! Since your podcasts revolve around focus and optmising efficiency of our biology, would love to have an episode centred around how ADHD impacts our neurobiology and how us ADHD-ers can be better versions of ourselves armed with the knowledge we get from all your videos!!
I wanted this so bad. This was an amazing podcast episode. The whole "The knowledge of the knowledge is an effector in and of itself" is an amazing concept. Overall I loved the podcast.
Can't believe I just found this. Glorious. Been a fan since watching his Stanford lecture series.
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.
Never have i being so attentive, i am learning more than i did at school ,absolutely marvellous.
My favourite episode thus far and I’ve been here since day one. Dr. Sapolsky is an idol.
I havent even heard this episode and i am so excited! Really big fan of Sapolsky’s work!
It's the best interview with Robert that I ever saw. Thanks a lots!
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!!!🙏🏽👍🏽😁❤️
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.
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.
thank you for what you do andrew! I appreciate your style of teaching. you are a gifted teacher!
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.
This was an incredible way to wake up. I feel so much calmer. Thank you so much!
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.
I share that appreciation too. Thank you for saying your final words Andrew and hosting this podcast. The knowledge does change peoples lives.
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.
Thank you for such insightful comments on HRT in the menopause. So glad you both talked about this. So important for the women in your life.
This was really tremendously interesting. Thank you Andrew and Robert.
I love Robert's lectures, I have learned so, so much. Thank you so very much Dr Sapolsky.. I owe you!!
Watched Mr. Sapolsky lecture on Stress year's ago...Simply fantastic...He's spot on...Obrigado from Portugal...🇵🇹🤙🤘✌
Words cannot convey how much I value and appreciate the ever relevant information shared in this episode.
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.
Sapolsky is brilliant, I always tune in to his discussions. His series of lectures at Stanford is well worth a look too.
Thoroughly enjoyed watching both of you on KZhead. 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.
Huberman and Sapolsky on Hormones and Free Will? Count me the **** in, I've been waiting for this my whole life!
I never realized how much I needed a discussion about free will from a science point of view... And now, I need more of that!
Simply brilliant, so much respect for this man
Honestly this felt very serendipitous as I've been on a robert sapolsky kick the last couple months as I have watched this podcast over the year.
Same here! Binged his Stanford lectures and I got started on Behave.
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
Amazing ! Thank you for running this channel and all of your work !
Sapolsky is a sort of science rabbi. Wonderful. Well done getting him on the show, Dr. Huberman.
