[Volcanopyre]

[MzTigerLily]

@c0ncerta  the reason sex is not against the law is because no one ever died from sex, but they do die from cocain,meth etc!!!!!!!

[sad4ewer]

The Science of Kissing -- are u people are mental ... u just kiss next video

[MichaelBradley1988]

bullshit, im rubbing my tongue against my teeth, lips and roof of mouth, and alls its doing is making me salivate....i think you'll find it has nothing do to with the tongue, its the fact you are knowingly kissing someone that you want to take a stage further, triggering an emotional response that will lead to something else growing.....CHA-CHING

[MysticalFlyingMonkey]

To be honest, I got slightly turned on by the nerve cells. This is what happens when I know so much about how they work weeks before the actual exam...

[MzTigerLily]

@c0ncerta if you made sex illegal then the human race would stop, dummy

[c0ncerta]

@MzTigerLily

No, People would still have sex without protection,etc... But what does that mean?, it would mean more wars,killings,etc its like normal people just wana get a little good feeling so they get some E , cocaine,etc (They do not harm anyone els infact they would be nicer to everyone els), but yet it is illegal and yet you can be Shot in some countrys for using it in your own home and sent to jail. This life is weird!

[c0ncerta]

Exact same ting as cocaine,meth,etc so why are Stimlaunts illegal?, why not make kissing and sex illegal?, Fuck you america old times ago a present made drugs illegal that fucking cunt fuck

[pauseTV]

@c0ncerta ... you stoned?

[xHaniffax]

@c0ncerta Because, you twat, Dopamine and other neurotransmitters are natural and produced by your own body, so your body has a way of controlling it. Your body is constantly striving for a state of balance. Substances like cocaine and other narcotics shift the balance causing disharmony which ultimately fucks up your brain and therefore the rest of your body. So, that is why some stimulants are illegal. Dick.

[c0ncerta]

@xHaniffax

Why is ciggeriates legal?

Why is alchool legal? <-- no work, / downer

cocaine <--- work , happy

ok, make e legal, also fuck you

[xHaniffax]

@c0ncerta oh, they SHOULDN'T be legal. the only reason they're legal is because the governement makes shitloads of money from them. And learn to spell fuckwit.

[c0ncerta]

@xHaniffax

[m4rkyboy]

Whenever i scuttle a bird i lick my own lips to increase the pleasue

[WaterBottle1998]

Dopa meeeaaan, doooopa mean, it's a catecholamine neurotransmitter, which means it sends a message in your brain, to tell you that you think that girl you're looking at is fitter, to make offspring with than any other dame....

[djpj22]

@WaterBottle1998 NERDFIGHTERS WILL TAKE OVER ALL THE YOUTUBE PAGES! (P.S. I hope you're a nerdfighter, and even if you're not, you like charlie, so that's cool too =P )

[WaterBottle1998]

@djpj22 I'm afraid you are totally wrong there my friend.....

NERDFIGHTERS HAVE TAKEN OVER ALL THE YOUTUBE PAGES!

And @HannahThunderify sure but dopa means just one half of the tale, the chemical that gets you in the mood, there's another that you'll need to prevail if you want to see me and 20 other people in the nude ;)

[djpj22]

@WaterBottle1998 but remember! dopamine is useless without norepinephrine focusing your efforts on one girl, telling you that she's the one that's making your head spin, if this were an oyster then she'd be the pearl.............

[WaterBottle1998]

@djpj22 [SeeLastComment]

[HannahThunderify]

@WaterBottle1998 Can you, I, and 20 other people have like a best friend orgy?

[nayrnayr93]

Hopefully it also covers the science of smashing a tidy lass's backdoors in.

[flabbyoldman]

@nayrnayr93 or better still two of them
