  1. Hey, hey, hey. Greek person here, what was that about the thumbs up? We do that ALL the time. Same meaning as you guys, what was up with that? I swear, I've never in my life seen a person use a thumbs up with a negative connotation

  2. I have a question… I'm a bit confused. Hank, you say that moderate stress releases adrenaline and cortisol which kick up the immune system which can heal wounds and fight infection. But I thought that stress hormones like cortisol trigger the fight or flight response which shuts down non emergency systems like the immune system… So firstly, are adrenaline and cortisol both hormone and electrical related and secondly, does the difference of the effect on the immune system arise depending on if the adrenaline and cortisol are either released by the endocrine system or nervous system?

  8. That gesture won't get you arrested in the Philippines. But when your Mom/Dad does that to you, you're more likely to get spanked with a tsinelas. (A flip-flop) ;~; xD

    (Unless, you know, the local cop makes that gesture at you. Then yeah, you're probably gonna get arrested.
    Or they suspect you carrying drugs, idk. Duterte, lol)

  9. I would like to contest an element of this presentation related to the identification of facial emotions being universal. I worked with a community of people where the language was oral, no written language and when shown various facial expressions they were only able to distinguish Happy and Sad. This is a profound discovery which I will be publishing soon to refute this universality concept.

  10. Could u do an episode about pain and why our precision of pain is not always the same. Thank you! I'm studying nursing and your videos really help me to understand things better!!!

  11. So true. Everytime i get stressed i have hair thinning around my temples and frontal region. It burns and itches. My body is litterally saying "no more, i will show you what you are doing to yourself when you over stress."
    Listen to your body, it loves you.

  12. I love these videos. They are so enjoyable to listen to it actually makes learning about psychology very interesting and "fun". I wish my class used these more of these videos as I have learning disabilities and I can "understand" what is being said, unlike our reading material that seems like it for someone in Psych for 3 years should know. My Intro to Psych is "not" an intro class, it is like a 2 or 3rd year class! I do not understand anything that is going on, being said period. Sigh…..

  13. Couldn't the association between positivity and health be a third-variable? Like people who are less stressed out by their daily lives will more likely have more healthy life circumstances that lead them to be less stressed out and also live longer? Like if they have more money?

  14. I love how people find all these “surprising risk factors” totals the fall for the heart disease epidemic. Fight that battle with your fork, don’t blame everything else

  15. A lot of the information crash course is giving on emotions is not in agreement with the scientific data from neuroscientists such as Lisa Feldman Barrett and Anil Seth. Maybe I'm listening to the wrong people, but what they have to say makes a lot more sense to me. Especially the fact that you can't actually tell what someone is feeling by looking at their facial expression. We have been socialized to group certain expressions with certain emotions, but in reality we use context more than facial expression to tell how someone is feeling (ie if they are crying tears or joy or sadness, etc)

  16. I wish my teacher just played these in class so I can just sleep and say I hate these to her face boo miss Newbury(I had a panic attack at the end of these video)

  17. 2:47 the thumbs up is a bad gesture in Greece? Damn I'm leaving in Athens for 20 years and I have never heard that before. I guess, now with the internet the youth has more universal gestures.

  18. What a guess dude tomorrow is my psychology test and the day after tomorrow is my "chemistry test stressing me out"… Oh thats so interesting 6:11

  19. Fellow Greek here. The thumbs up gesture in Greece doesn't mean anything other than "good job" or "ok". Got it wrong here Crash Course. Putting up and opening all your five fingers with your palm facing another person means you are very angry at them and think they did something stupid or they are basically assholes

  20. Stress have all to do with the sensation of control. You dont get stressed with things that you don't think you can change or control, Independent if that control is real or not. That's what says the neurobiologist Suzana Herculano.

  21. im from the philippines and im gonna wrong you like how grammarist are gonna wrong me now.

    nothing was wrong with that gesture 😅

  22. dude why did you have to tell me that PTSD fact i have ptsd and anxiety so really dude. (edit) and your telling me im more lkely to die because im usually stressed and i have on and off depression, I think it was major depressive disorder idk though

  23. Please slow down the verberation of the tempo. I cannot pick up what your putting down. Overall though, Thank you for all the content and time invested. 👍

  24. Over 30 years of counseling and this video alone taught me more than all of my combined therapists.
    Both a sad commentary on the state of mental health awareness and a massive compliment to all of you at Crash Course. You are changing my life for the better. Thank you.

    (Yes, ,I'm watching the whole series. )
