Your genes are in control. Your genes are using your body as a temporary vehicle until you mate and have offspring, in which the genes can be passed on to and live on in, while you wither away and die.
This is why you start to age not long after you finish puberty, as normally animals would mate and reproduce during this period, and your genes have no use for your body after this point. Genes and DNA don't give a shit about emo this and muscle that, as long as you fulfil the powerful biological urges provided by your masters, your genes.
cultural, society 's rules affect biology of the brain and body. The more medias promote homosexuality , the more kids are abandonned by their parents in front of tv and get brainwashed, the more our society will produce homosexuals as a result.
There were less homosexuals when society didnt talk about homosexuality 24/7. I'm not saying it is "bad "or "good" , I'm just stating facts.
This is a fact. Environment affects our biological, physical internal mechanisms . It's all a question of conditionning and exposure. You guys should read about the plasticity of the brain , and as a result Thought, and how it is affected by cultural, social, educational stimulis 24/7.
Everything affects everything.
