I am a metalhead girl and I like headbang my head in rhythm of good black/death metal songs. My favorite headbang technique is called Windmill! \,,/
Generally headbanging is not really dangerous. According the amount of metal concert that I did, I have never had severe trouble or loss of consciousness, same for other metal guys present in the concert hall. Just muscular pains the day after like you have muscular pain after going to the gym. Also loss of equilibrium during the first minute after headbanging, it is normal the vestibular system is completely shacked and it is worst with couple liter of beer so nothing really serious.
I said “generally” because at least 2 cases of injury were reported: Vertebral Artery Aneurysm and Subdural hematoma. Ok, it is not a safe practicing but still it is not common injuries.
I will not going into the detail of the method and their mathematical model which are not adapted to headbanging because the model is for one head circular moving (angle are from 40° to 120°) and not a periodical head moving. Also and in my opinion the result are extremely overestimated. Seriously, if they really wanted to speak about a potential injury caused by headbang, they should have take songs which the tempo goes above 180 bpm (beats per minute). Because 180bpm is slow, black and death metal have a tempo between 180 and 240 bmp. Then, 120° for headbanging is ok, but why not more? Windmill technique asks more than 120°. Overestimated because and according their model, headbanging (remember it is just one acceleration of the head, not a real headbanging) with an angle of 105° at 160 bpm should induce unconsciousness during less than 1 hour and with an angle of 120° at 180 bpm should induce unconsciousness during 1 to 6 hours!!! I many time headbanged with a huge window of head moving, really quickly and more than 5 minutes nonstop or 1 hour cumulated during the concert and I never had a loss of consciousness neither people around me.
Now, Hellbrothers and Hellsisters, let’s have fun! The authors of the paper give us some advice to avoid and prevent damage and neck/brain injuries caused by heandanging. Are you ready to laugh?
Advice 1: Neck Training
It is make sense. Like for making sport, training before and after could help to avoid muscular soreness the next morning. Now just imagine a concert of Mayhem when the singer says to the audience: “before to start the concert, we all are going to train our neck during 5 minutes! Come on guys! Head circle movement… yes like this”. Do you imagine a concert hall full of metalhead which black and with painting on their face and wearring beautiful dark clothes with big pikes making neck training? No, me neither.
Advice 2: Asking AC/DC to stop playing the song Highway to Hell for the song Moon River of Andy Williams. (No it is not a joke, they have seriously written that)
If you have no idea about Andy Williams and his wonderful song Moon River, this video will help you!
Advice 3: Wearing medical neck protection
Well, but only if it is customizable. In black with long pikes?! How can we headbang with that ha?! Oh yes, i forget… headbanging is the son of Satan we have to stop doing this.
Advice 4: “substitution of adult oriented rock and easy listening music such as the controls (cf Whitney Houston, Lionel Richie, Styx), or others including Michael Bolton, Celine Dion, Enya, and Richard Clayderman, for heavy metal”
Yes I laughed like hell when I read that! I just imagine all fan of Deströyer666 going to a concert of Celine Dion and Richard Clayderman. It would be wonderful.
Conclusion: Metalheads! From now and for your health (it is sciences who said!)
You will no more listen to Lord Belial but Michael Bolton.
Lord Belial – Devilish Enlightenment
Michael Bolton – Said I Loved You…But I Lied
You will no more listen to Arch Enemy but Céline Dion.
ARCH ENEMY – Nemesis
Celine Dion – Pour Que Tu M’Aimes Encore
You will no more listen to Blotted Science but Richard Clayderman.
Blotted Science – Synaptic Plasticity
Richard Clayderman – Ballade pour Adeline
Yeeees that’s scary my like heaven too! Too bad for the potential injury caused by headbanging, I will not stop it and I will not change my musical taste for this… hmm… this music which they advice us. NO WAY!
Actually, seeing a handsome guy with long hair and a goat who headbang, it excites me . Also it is really useful to be closed to a headbanger when it is really hot inside the concert hall, he/she is a human-fan.
Seriously headbanging is not a safety practicing (ok like everything :/). If like me, you will continue to headbang even this caution, at least if you have any kind of symptoms, pain, extreme dizziness (not just loss of equilibrium less than 1 minute just after a session of headbanging), alteration of consciousness or whatever which seems not usual or not normal, stop immediately shaking your head and in case consult a doctor. It will be to bad to miss concerts of Lord Belial’s ressurection.

Several studies point the fact that beer is good for the bone mineral density in men and at least postmenauposal women. In fact not only beer but also wine seems to be good for the bone.
When I say alcohol could be good, you have to keep in mind that it is MODERATE alcohol consumption! Of course heavy alcohol drinking is bad for health and also bad for bones!
Scientists don’t really know why this moderate consumption of beer and wine are good for bones. At least three components are possible involved:
Silicone. Beer contains the major source of dietary silicon and silicon itself seems somehow act on bone formation.
Ethanol could also have this protective propriety by acting itself on suppression of bone resorption or by acting on oestrogen concentration.
Estrogenic resveratrol contains in wine could have a protective effect against bone loss.
In conclusion something is good for bones mostly in beer and also wine but not in liquor. So a moderation consumption of beer could be good for health, yes moderation. Anyway more studies are needed to understand how beer has these protective proprieties.

Guys, today you will know that your musical taste is crucial for your sex appeal.
Thanks to BlackWolf, he has found a paper named Effects of Associating with Musical Genres on Heterosexual Attraction. The only problem is my university doesn’t have access to the journal communication research, so i only have access to the abstract and the post on the blog laweekly.
Apparently our kind of music reflects our values, i.e. listening shit pop music means conformity, rock means rebellious, jazz means open to experience… Rock = rebellious? lol! So what about black metal? No seriously, rock doesn’t mean rebellious at all!
Anyway, some types of music are more attractive than other according the study of Zillman and Bhatia.
The conclusion is
Guys and Girls don’t say that you love country music because you will repel the opposite sex! If you are a guy (opposite effect for women), don’t hesitate to scream your love for heavy metal it will give you a rebellious touch that every girl like. Girls (opposite effect for man) your classical music taste helps you to attract guys! Also man care about the musical taste of women and whether they share the same contrary to women who don’t care.
My opinion
Well, well, well, I am a metalhead and I can’t really imagine myself being with someone listening completely opposite music like white metal, Christian rock, reggae/ska, pop / rock and so on. Because I spend a lot of time in metal bar and concert and by concert I mean metal concert, no other kind. I am ok with blues, rock 60-70’s and classic music because I like that too.
Actually it is at least a little bit true about musical taste reflecting value. I mean if guy says to me “I listen to pop / rock music” or “I listen to radio” I clearly run away as fast as I can! For me someone who listens to pop or rock is a boring and simple person. Ok I don’t mean that every guys who like pop are simple but this kinds of music reflect these values for me, so I avoid them! Finally if I like people who listen to black/death metal it is not because it sounds “rebellious” or “unconformity” but just because I like this type too.
Anyway, guys, listen to music that you like, don’t change it for anyone!

Guys, today I am going to explain you how to detect whether your girlfriend want a baby… in fact, it is not so simple and clear.
Let’s talk about female orgasm. As you know, orgasm gives us a huge pleasure but actually female orgasm has not this unique pleasure function, it is also facilitated sperm retention (= less sperm is thrown out from vagina after ejaculation). Studies of Baker and Bellis have shown that there is an increase of sperm retention when the woman has an orgasm from the moment of male ejaculation to 45min after. No difference on sperm retention if the orgasm is before male ejaculation or without orgasm at all. So, female orgasm could help to increase the probability of conception.
Ok, now, you know that orgasm is probably not only a simple pleasure distributor and could have a 2nd function on conception. From that point, Singh et al. wanted to know whether there is a relationship between the woman’s desire of to become pregnant and the timing of her coital orgasm and the answer is on this paper : Frequency and timing of coital orgasm in women desirous of becoming pregnant.
How they have done that?
They have asked to 69 volunteer (ahahah exactly 69, coincidence? xD), mean age: 31.7 years, to fill a questionnaire about: personal and sexual history (i.e.: religion, duration of marital relationship, age at first masturbation and sexual intercourse, masturbation frequency, active or passive during intercourse…), coital orgasm and desire for pregnancy, and Hurlbert Index of Sexual Compatibility.
What are the results?
• Duration of genital and nongenital foreplay is a predicator of frequency of coital orgasm.
• Higher frequency of coital orgasm for women who are active/take in charge during the intercourse.
• Desire for pregnancy is not related to overall frequency of coital orgasm.
• Desire to become pregnant is predicted by frequency of orgasm after partner and by the desire sexual participation.
Conclusion Briefly: Women who want a baby have more orgasm after partner ejaculation.
Not Briefly: The frequency of coital orgasm is related to duration of genital and nongenital foreplay, sexual compatibility, active sexual participation, masturbatory frequency and marital happiness.
The desire to have a baby / becoming pregnant is predicted by 2 factors: – Active sexual participation, which is an independent predicator. By taking in charge the intercourse, woman is enabled to manage her orgasm timing. – Frequency of orgasm after partner. It supports the study of Baker and Bellies which say that having orgasms after male ejaculation help for conception by increase of sperm retention.
Caveats: They have clearly written “caution should be used in interpreting these results” caused of regression analysis and boring statistical reasons. Also there are only 69 women, all nurses in military medical center = it is not a random sample. Also, this study doesn’t mean that having orgasm after male ejaculation help or is effective to have a baby. Then, “the role of female orgasm is multidimensional‚ subsuming affective‚ cognitive ‚ behavioral ‚ and evolutionary factors;” and this is a study about evolutionary explanation of orgasm, so no psychological component is assessed or taken account. Finally correlation doesn’t mean causation.
What I think about this study?
According the caveats, more studies about this evolutionary explanation of orgasm are really needed to clarify and approve or not this study and the work of Baker and Bellis. Their theory has sense but as Sing et al say “the role of female orgasm is multidimensional” and here only one dimension is studied. Even if this theory reveals to be true in future, I think that we have to keep in mind that orgasm is multidimensional and this study/theory is focused on 1 dimension therefore doesn’t explain the whole orgasm phenomenon.

Guys, actually Girls I will give you a hand-reader tip to be able to know if a guy want only short-term-relationship. Well it is not really that, and my title is too much and not exact, so let´s see what this scientific paper of Schwarz et al. says: “Short- and Long-Term Relationship Orientation and 2D:4D Finger-Length Ratio”.
Briefly the article says that prenatal androgen (like testosterone) influence brain development and one possible indicator about this prenatal androgen level is the 2D:4D finger-length ratio (ratio between the length of the 2nd and 4th finger of the hand). More testosterone is present in amniotic fluid during pregnancy, lower is the 2D:4D finger-length ratio. If I badly resume this sentence, it means more testosterone was present when you were inside your mother, more your 2nd and 4th fingers are the same size, and as you know testosterone is associate to male characters (well you have to know that women also have testosterone but in lower quantity than men and testosterone is a precursor for estrogen). So the 2D:4D finger-length ratio is higher in women than men (this week-end I will check that with my friends…).
The correlation between this 2D:4D finger-length ratio and the kind of relationship wanted or sociosexual behavior and attitudes is controversial. A recent paper says there is no correlation between the sociosexual behavior (assessed by the Sociosexuality Orientation Inventory, which assess the sociosexual attitudes, desires, and behaviors) and the ratio between the 2nd and 4th fingers. The paper of Schwarz et al. agrees with that but also says that there is a correlation between Short-Term Relationship and 2D:4D Finger-Length Ratio only in man.
How and what they have found?
Part I
They have asked to 91 men (mean age = 24.3 years old) to fill the Relationship Orientation Questionnaire (assessed short / long term relationship orientation ; see the end of article) and their 2nd and 4th fingers were measured from the baseline to the top of the finger. The results are: There is a negative correlation between the 2D:4D ratio of the right hand (but not the left) and short-term relationship orientation, but there is no correlation with the long-term relationship orientation.
Part II
They have asked to 207 participants (142 women, 65 men), with a mean age of 23.89 years to complete several questionnaire related to sexual behavior and relationship including the Relationship Orientation Questionnaire and the Sociosexuality Orientation Inventory (SOI) and their fingers was also measured. The results are: Left 2D:4D ratio is lower in man than women but not the right 2D:4D ratio. Women have higher long-term relationship orientation and social desirability score than men, and men have higher score in short-term relationship orientation and SOI than women. Finally the only correlation that they have found is a negative correlation between the 2D:4D ratio of the left hand in men and the short-term relationship orientation. No correlation with the other questionnaires, neither with the right hand men and no correlation at all with women.
What they have concluded? I will just copy past the conclusion:
“Taken together, these findings might indicate that men’s desire for sexual variety (Short-Term Relationship Orientation) is related to early androgen activation, while the desire to engage in long-term committed relationships (Long-Term Relationship Orientation) is not.”
They had weird result because in one case the correlation is shown only with the right hand and in the second case only with the left hand in men. So they say more studies and replications are needed to understand why they have this difference.
Here the questionnaire before to start to speak about my opinion.
Relationship Orientation Questionnaire
Short-Term Relationship Orientation
1. I want to conquer as many partners as possible.
2. I would like to respond to every flirtation.
3. I can easily imagine having sex with somebody I won’t see again.
4. For me, there is nothing to be said against having sex with a stranger.
5. I want to have as many relationships as possible.
6. If I could, I would have sex with as many people as possible.
7. I can easily imagine having sex with an unknown person, if he/she is physically attractive.
Long-Term Relationship Orientation
1. My partner has to want children.
2. When I have found the right partner, I would like to settle down with her/him.
3. My partner must be able to handle children well.
4. Warmth and comfort are necessary parts of a relationship.
5. I would like to have a partner with whom I can get old.
6. My partner should give me a certain feeling of security.
7. It is important for me in choosing a partner that she/he could be a good mother/father.
What is my opinion about this paper?
I agree with:
They say something that I agree in their conclusion:
“From our point of view, androgen influence primarily psychological attitudes and desires and do not influence whether a person is able and has the opportunity to fulfil these attitudes and desires, i.e., to actually engage in sexual activities with different partners.”. In my opinion I also understand the possibility that our desires and attitudes are affected by prenatal hormonal level, but of course this desires and attitudes are achieved or not, are maintained during life or not, are changed or not according the external/internal environment and social conditioning. It is like genetic VS environment, there is no supremacy of one of them, and environment will modify the gene expression and so one.
I don’t agree with:
But concerning the questionnaire I am quite skeptical. Because, and I will again use my case in example and I am not the only one who think like that, it is possible to have a high score the Short-Term Relationship Orientation and also wanted a long-term relationship. I mean both questionnaires could be compatible. It is really possible to want having sex with unknown person, having one-shot night partners, friend with benefits, changing sexual partners often, and when the good one is found or wanted to find the good one to have a long-term relationship forgetting one-shot, ending to want to conquer many partner and sexfriends become friends. That is the reason why I think this relationship orientation questionnaire doesn’t reflect the real feeling/wanting about relationship.
More studies are really really really needed to know more about this potential corelation and also about this possible marker (2D:4D ratio) of prenatal endrogen marker.
So, do woman have to check the fingers of a guy before to start a relationship with him or choose only guy with a high 2D:4D Finger-Length Ratio?
I say no! This paper says clearly that the desire to engage in long-term relationship is not correlated with this finger ratio. Actually it is more related to oxytocin, vasopressin and NGF which are involved in love, falling love and long-term commitment. Conclusion: Even if apparently guys want more short-term relationship than women, and mainly those with short finger ratio, they can fall in love or want to start a serious relationship with someone. Also and remember it all of your life: Correlation doesn´t mean Causation!!!

When I have started this blog I didn’t know if I wanted to only speak about sex scientific fact in human being or also in other animals until I see a porn picture about double penetration in vagina of a whale! I want to put my family and friends to rest, I am not a zoophilous and I didn’t see that on a zoophilous siteweb!
So yes guys, you have read well, also whales can have a double penetration in the same hole like in porn movie according this paper “Observations of a Female North Atlantic Right Whale (Eubalaena glacialis) in Simultaneous Copulation with Two Males: Supporting Evidence for Sperm competition”.
First and thanks to this paper, I have learned that the weight of whales’ testes is 1,000 kg and I am really happy to learn you that right whales possess the largest testes in the animal kingdom, also the penis of this right while is disproportionately long (around 2-2.5 m, yeees metre!).
Secondly it is apparently known that whales females make gang bang but never with two guys in the same time in her vagina. But now, we have the proof with a beautiful picture (see after). According Mate at al. in right whales there is a sperm competition (quantity and quality) between whale males. Here a wonderful picture of double penetration or as they called it “simultaneous copulation / intromission”, this double penetration itself lasts 40 sec (yes only 40sec):
Finally the paper give some explainations, it could have a sperm competition between these two whale males by possibly “wash out” of sperm from the other guy in serial or simultaneously. Also apparently it is frequently that whale female lie upside-down on the surface so that only male with long enough cock is able to penetrate her.
Also they say: “For anatomical reasons, double copulation would be difficult or impossible in most mammals”, I saw some movie… I’m not saying, I’m just saying.
Conclusion: Whales have really big penis and testes. Female whales like gangbang. We can see double penetration inside vagina outside porn movie and in animal kingdom. Don’t forget, the size of the penis doesn’t matter, it is how the guy use it.

Guys, when you are in a bar, drink your fresh beer, relax and listen to metal music, you absolutely don’t care about molecules floating inside your beer. You are already pissed off because people tell you “you drink a lot”, “alcohol is bad for your health”, “alcoholic blabla”… yeah, yeah, yeah I know, and if tell you that your beer is good for your health?! One component of your beer called xanthohumol is good for you, it could prevent cancer and could have an antioxidant effect, oh yeah just that!
What is Xanthohumol?
No, it is not a new black metal band, it is a prenylated flavonoid contained in hops which is one of the main constituent of beer. There is not only Xanthohumol on beer but also other kind of prenylflavonoids. Here a representation of the molecule, beautiful isn’t it?
In what my beer could be good for my health?
Xanthohumol and also some other prenylflavonoids of beer have 4 good effects for health:
Antioxidant properties: Like fruit and vegetables, beer also has molecules which are antioxidants. That means this Xanthohumol is able to clean reactive oxygen species which are harmful for cells.
Xanthohumol is cancer chemopreventive agent which acts by: inhibiting the metabolic activation of procarcinogens, induction carcinogen-detoxifying enzymes, and by inhibition of tumor growth at an early stage by inhibiting inflammatory signals and angiogenesis. That means this natural molecule could prevent cancer in different ways.
There is also but really small estrogenic activity and so could be help for perimenopausal problem.
Xanthohumol and humulone are inhibitor of bone resorption. It will be mostly useful for women after menopause who have higher risk of bone problem and osteoporosis.
Good news and Bad news
The good news is that xanthohumol is not especially toxic for liver and mitochondria. The problem in cancer therapy is the potential toxicity of long term use of chemoprevention drugs, so here xanthohumol is a good participant to be a good cancer chemopreventive agent.
The bad news is that all of these health-promoting properties were done in vitro (with cells) and so the quantity of xanthohumol in beer is probably low to have these good effects. But by increasing the quantity of xanthohumol in hops and have beer with high level of this flavonoid, it could be really interesting.
Conclusion
Xanthohumol which is found in beer seems to be a good natural molecule to prevent cancer. But there is probably not enough inside the beer to produce these good effects on health; this problem could be solved by creating experimental beers with high levels of this flavoid. Finally studies are still needed to know more about this xanthohumol and also if there is side effect.
CAUTION!!!! Even if beer seems to have good effect on health, don’t forget the bad and toxicity effect of alcohol! I am not here to tell you to stop drinking except for 2 kinds of people: those will take the road –> DO NOT drink before to drive car; and women who are pregnant –> DO NOT drink at all (even a small amout) of alcohol when you are pregnant!
For the rest and mostly for us metalhead, we can drink beer and taste this Black Metal Imperial Stout beer. A black metal beer! Because Black metal music was played to beer during fermentation! Oh yeah! \,,/
I have never tried this beer but I would like… even if I don’t like chocolate, chocolate tast and chocolate flavor.
Sex is good for health! One reason is the propriety of sperm to be antidepressant. Guys! Now if your girlfriends/night-one-shot girl/wife/friend-with-benefit/whatever-is-your-relationship-I-don’t-care-it-is-not-my-business doesn’t want to have sex with you, you can use the scientific excuse: “My dear, you have to know that my semen have a good effect on your health and you will have less mood disorder, so can I take you on the kitchen table NOW!”. Actually it works also for women: “Listen to me well guy, now I want sex, ok! If we don’t do that, I’ll be depressed and it will be your fault!”
I am sure you are asking if it is work for oral sex and swallowing?! The antidepressant propriety of sperm was not yet shown by swallowing way, only by vaginal absorption (I will discuss about that later). But that doesn’t mean swallowing sperm is not good for health, actually it could prevent pregnancies diseases like preeclampsia or pemphigoid gestationis.
Let’s talk about this antidepressant effect of sperm! Globally sperm is composed of many hormones like testosterone, estrogen, FSH, LH, prolactin and prostaglandins. Actually estrogen is already known to be involved in mood, so it is one of the “best” candidates for the antidepressant effect of sperm.
Gallup et al asked this really good question “Does semen have antidepressant properties?” For answer it they ask to 293 female students some question about her sex life (frequency, when the last intercourse, which kind of contraception and if they use condom). The authors have divided them in 5 groups according the condom use: Never, sometimes, usually, always and no intercourse. Then these women had to answer to the Beck Depression Inventory (BDI), it is a questionnaire which assesses the level of depression. Lower the score is, less depressed you are.
What they have found?
Women who don’t use condom have a BDI score lower than whose use condom or don’t have sex at all.
There is a correlation between the BDI score and the days since the last intercourse. More days are since the last intercourse, higher the BDI score is.
The attempt to suicide is higher for women who used always/usually condom or don’t have sex.
Women who don’t use sex have more often intercourse. The loss of sex appetite / libido is one of mood disorder’s symptoms.
What about counterarguments? The scientists have made some statistic analysis to exclude counterarguments. For instance they have verified that, oral contraceptive, kind and length of relationship, frequency of intercourse, behavior and risk taking, have no correlation with the BDI score.
Conclusion
First of all: Correlation does not equal causation! This is for all statistic of all scientific paper!
Then I am depressed… and I want to be cured…. So…
Finally there is clearly a significant correlation between intercourse without condom and low BDI score and also between intercourse with always/usually condom use and high score of BDI. Why and how that works? Nobody knows yet. That’s the reason why more experiments have to be done, assessment of hormone’s level in blood, finding which hormones are involved, verifying if this antidepressant propriety is only present when the sperm is absorbed by vagina (or uterus) or also by oral and anal absorption. More seriously this research can open the way for new kind of antidepressant drug. Less seriously I just imagine the advertising slogan of an antidepressant made with sperm, mostly for women who have no relationship/boyfriend: You fell depressed? Drink sperm every morning at the breakfast and it is 100% organic!
So having sex is more than just for reproduction. It activates your pleasure and reward system of your brain and also keep your health better.
Before you go reduce your depression, HIV is still here, still present and still fatal, there is no cure for it!!!! So use condom when you are not sure that you and your partner are safe!

Hi, I am neuroscientist and my mojo is “Sex, Metal and Sciences (+ Beer and video game)” and as I like to speak about neurosciences to non-scientific people, I have decided to create this blog to explain you funny – interesting – weird – scientific facts about sex, metal music, beer and video game, so all the best things of the world
English is not my mother tongue so please don’t blame me about my bad English writing. I am French (yes it is a true cliché, French don’t speak foreign language :/).
Finally, don’t hesitate to comment, correct mistakes, bring your ideas and views.
. Also it is really useful to be closed to a headbanger when it is really hot inside the concert hall, he/she is a human-fan.
