Pain, Olfaction, Pheromones, and Synaesthesia

Pain, as much as we hate it we need it. Without pain we wouldn't be able to survive as long as we would. Our body uses pain sensors to warn us of pain. Over time our body goes through different levels of pain and adapts in different ways such as our brain tells us not to touch fire anymore or when getting hit with a thrown object causes you to learn the thrown object is a danger to you and to avoid it. Some people have an obsession of pain, in regards of stopping it. Lots of people want to avoid pain but can't, so to those people the easiest way to avoid pain is to use or abuse drugs legal or illegally. This obsession with relieving pain is very dangerous, and lots of entities exploit that obsession, like the promotion of cigarettes and alcohol.

Below are two videos that explain in greater detail of how pain works and how people experience pain.

The first video is about how pain relievers work.


How Do Pain Relievers Work? - George Zaidan

Learn about the basic physiology of how humans experience pain, and the mechanics of the medicines we've invented to block or circumvent that discomfort.



 This upcoming video is of my favorite place to learn new information, TED Talks.


Elliot Krane: The mystery of chronic pain

About:

We think of pain as a symptom, but there are cases where the nervous system develops feedback loops and pain becomes a terrifying disease in itself. Starting with the story of a girl whose sprained wrist turned into a nightmare, Elliot Krane talks about the complex mystery of chronic pain, and reviews the facts we're just learning about how it works and how to treat it.

At the Lucile Packard Children's Hospital at Stanford, Elliot Krane works on the problem of treating pain in children.
