pills, timing, taste in kiss- something we can't control=useless.
saying from right side>left side-hmm, there is enough brain masturbation out there-why create more?
using fear- Interesting
In one of studies, they examined the brain of people who are "in love" basically they found activity in brain regions responsible for dopamine production(addictive pleasure hormone) and small part of the brain which is usually activated when something stressful happens to us. Interesting...very interesting. Would be quite easy to make people fall in love with each other by just doing something stressful, and then something nice right away. if somebody tried- tell me please, but common sense tells me it doesn't work. It might, but we aren't at the point of understanding the brain were we could make any use of it.
What I'm saying can easily be wrong, but I believe one of the main reasons for our inability to play with people's minds just as we want(which I'm hugely glad about) is because there is more than one part of the brain responsible for the same situations. And I'm not even going into the whole brain plasticity thing, since its gonna make tings even more hopeless for manipulative scientists lol
I've encountered this staff a while ago,(when I was into pheromones and staff) and studied it for a bit, but the only conclusion I came to is that brain is too inter-wired for us to make any reasonable conclusions and more importantly any use of them. There are simply many different receptors, and types of the same hormone in our blood to be able to somehow affect it. Even dopamine which is supposed to be quite simple pleasure hormone has bunch of subdivisions, each produced when different receptors are activated. Also there are bunch of other pleasure hormones in this whole love/lust thing. Even scientist themselves didn't come to any conclusions, all we have is vague theories, mostly based on empirical science(they're just observing it in MRAs(look at what they base their conclusions in all these documentaries)
Punchline-don't try to mess with people's brains(that's why I stopped the whole pheromones thing-some guys are practicing hypnosis-I'm not a specialist in it, but I wouldn't suggest going into this, if you're not professional)
i guess this post was a bit too long
