Geoffrey West touches upon some of this stuff in scale - its worth a read

Oversimplification is that some of the viruses / genetic defects that kill us later let us live long enough to reproduce first and pass those traits/infections along.
- 876ret 8y agoThe ancient Egyptians liked cats, and considering the effect T. Gondi has on males[1] (higher Testosotorone & dominance) and females[2] (submissiveness), this could have been a reason why they worshipped cats. It could also be considered an early example of a biological weapon used on sections of population. With regard to addictive behaviour, some research has suggested addictions are neuro amine addictions, ie andrenaline, dopamine & serotonin. Cocaine for example last in the body for upto 2hrs and amplifies dopamine and serotonin, so being addicted to feeling good is understandable, however serotonin also plays a part in the innate immune system and the association between depression and illness has also long been known. The medical profession SSRI's inhibit the uptake of serotonin in the brain, which reduces the brains ability to convert it into melatonin (4x more potent than Vit C), plus not much can cross the blood brain barrier so the adapative immune can not work in the brain, eyes, gonads, ovaries. So whilst SSRI's can make you feel good, like everything in life it can also have its side effects because we are a bundle of realtime complex pathways oscillating in time and space. One other point of risk taking behaviour, some of you may have noticed when you feel like you are going down with something like a cold or flu, you may also feel the need to procreate before the illness takes hold. This would suggest an evolutionary response to pass on genes, but excessive amounts of chemicals which can harm the body can also cause this behaviour as well, illegal drugs & alcohol being examples. ie did you know that smokers have elevated levels of copper in their blood stream? This is probably due to the need to deal with the risk of foreign bodies coming into the blood stream through the lungs, but copper and iron is also required to prevent anemia, which in turn is required to make red blood cells, plus its also known that elite atheletes, people living at high altitude and smokers have enlarged red blood cells. Plus smoking can also be a form of self medication if an asthma inhaler is not available, asthma being a type of allergic reaction to debris or pathogens inhaled, most commonly being from pets or pollution.
