Doctor's Note

Did I say "Mozart study"? I had fun with that in my videos Music as Medicine and Music for Anxiety: Mozart vs. Metal. I don’t go seeking out these peripheral topics; I just stumble upon them in the journals. There’s so much wonderful juicy medical science out there. I wish there were dozens of different type resources where one could find evidence-based reviews of the latest in the science of wellness. There could be another ten or so just on nutrition alone! If anyone out there is interested, I’d be more than happy to share all my know-how to facilitate their creation. I helped the Lifestyle Medicine Foundation develop – coming soon!

  • Chanjw

    Thanks for the laugh. I already feel better.

  • Joe Caner

    Wow! I never expected to hear the following phrase from Dr. Greger, “injected with dust mite poop.”
    I certainly would not want to take part in that study.


      Check out the video “Bristol Stool Scale”. Dr. Greger practices what this video preaches. Hurrah!!

      • Ann Blanchard

        I’m sorry I didn’t save the picture of the Bristol Stool birthday cake Dr. Greger’s staff gave him. It was a HOOT!

    I need to know was the kissing just on the lips or did it require a session of tonsil hockey?
    Thanks for the organasmic info! :)

    • Kim Churchman

      In Japan? Probably never heard of tonsil hockey.

  • Maureen Okun

    One substitute teacher (native English speaker) once greatly helped the immune systems of my high school biology class by telling us that there were many interesting orgasms in the Pre-Cambrian explosion. I don’t think anyone had a cold for weeks after that.

    • SeedyCharacter

      You just gave me an immune system boost! Too funny. Was the teacher aware of his/her blooper or oblivious to it and wondering why the students were contorted with suppressed giggles?

      • Maureen Okun

        The poor man was aware of the slip as soon as it happened. He stumbled through the rest of the lesson with a very red face. I’m guessing that mortification isn’t so good as an immune system builder.

        • SeedyCharacter

          Oh, poor fellow. But I’m guessing he had a good laugh about it when he went home that night and shared the story with his significant other. Here’s hoping anyway!

  • Darryl

    My natural killer activity goes up watching an hour of Gallagher, too.

  • Noe Marcial

    looking foward for

  • Noe Marcial

    so after lough for an hour NK go up almost double? it is amazing! and not to mention how interesting are all the benefits of kissing and have many organisms :)

  • Noe Marcial

    it can be that crying is less effective than laughing? if that.. so maybe better to watch a comedy tonight :)

    • lilyroza

      It’s probably healthier to have a full range of spontaneous emotions and not be repressed. Or to say it another way, repressing emotions and expression repress the immune system? Empathy can make you sad because you feel others’ suffering. I cry at movies, and sometimes commercials. Of my six siblings, I was the biggest cryer, oh the injustice of it all. I was an emotion generator. Now I’m probably the happiest (though not the richest). Also, because empathy encouraged me to adopt a vegetarian diet at 22, I have gotten healthier while they have gotten fatter and less healthy. So I think that the ability to feel sorrow keenly is something of a guidance system to eventual happiness.

  • Janet

    Does laughter from tickling work?

    • Joseph Gonzales R.D.

      It might! I mean from the video it “wasn’t the funny video that improved immune function, but our laughter in response.” So perhaps any way we can laugh more is going to help.

    • Thea

      Janet: Interesting question. I remember mention of some research done several years ago that talked about how frequent, big smiling could improve someone’s depression. And that it didn’t have to be spontaneous, “Oh I’m happy” smiling. I think the study participants put a pencil in their mouths (bit the pencils like a horse bites a bit?) to force their cheeks out and up. And the study participants still had a decrease in their depression (or whatever was being measured).

      I don’t that such “fake” stimulus would work as well in regards to the topic of this video, but based on Joseph’s reply and the above study with the pencil, I tend to agree with Joseph that laughing due to almost any reason (except maybe a brain injury or mental illness) would produce the same results.

      Even though I just said that, I had this thought/question: What if the laughter is mean spirited and at the expense of someone else? Does the person doing the “negative laughter” still benefit? I won’t speculate on the answer. I’ll just say that I hope they don’t study this question.

  • Blaice

    Bill Cosby was never even CLOSE to funny. Maybe it is just my generation who found him incredibly uninteresting (I’m 26). If anything he was depressingly dull, and evidently more feared than humorous.

  • Siri

    I actually laughed out loud at the end of this video. Thanks Dr.Greger.

    • Julie

      Me too! Excellent way to end the video.


    Dr. Greger, you are amazing! I can’t begin to tell you how much you have enriched our lives. You might like knowing that is the basis of a six-part free nutrition course to the teachers in North Hampton School, NH. I helped inspire a program in which we built a greenhouse and outside garden in which every student (425) from preschool to 8th grade has their own 1 square foot garden in the greenhouse (grades pre-k to 3) and then their own 4 square foot garden outdoors (grades 4-8) to grow veggies EVERY year. We have completed our first year. What teachers know & internalize they will benefit themselves and communicate to their children as they see fit. My wife & I will be attending (again) your standing (and floor-siting) room only talk at The 2015 Boston Food Festival on Saturday, October 24th a 3:15 PM.

    • Doctor Dave

      There is a lady named Antonia Demas, PhD, who has created a curriculum for primary school called “Food is Elementary.” This is based around gardening and showing kids where food comes from. It is strongly supported by T. Colin Campbell, PhD, who was her thesis advisor, I believe. I strongly recommend this material for primary classroom and kid gardening support. Best wishes.

      • Joseph Gonzales R.D.

        There is a free recored lecture by Dr. Demas at Nutrition CME! Thanks for mentioning her work.

    • Julie, Wow, your nutrition and gardening program sounds awesome! This is what ALL schools should be doing as our children desperately need to embrace healthy eating. Doctor Dave beat me to it. I was also going to recommend the “Food is Elementary” program.

    • Joseph Gonzales R.D.

      Amazing! You’re doing such great work with the garden. I totally agree it creates the right education being outdoors, digging in the dirt, and being connected to your food! Thanks for the nice words I know Dr. G appreciates everyone who comes to his talks.

  • Tikiri

    “…females having more organism…”!! Thanks for laugh, Dr. Greger!

  • Kim Churchman

    The way Dr. G said ‘looove’ made me laugh!

    • Ⓥince Green

      I replayed that bit e few times :D

  • bbq

    No kidding, that doctor was actually given the Ig Nobel Prize in Medicine earlier this year:

  • Sweetie Bean

    So your videos are doubly useful – very informative, and I always laugh out loud!

  • ZBA

    maybe women truly do have more “organisms” :-)
