> (how could one's drive possibly impact biological life? There's a wealth of literature on these topics, but I'll leave this here: https://www.ncbi.nlm.nih.gov/pubmed/26729882 https://www.ncbi.nlm.nih.gov/pubmed/26729882 It shouldn't be mysterious, your outlook and mood determine your behaviors. However, it goes deeper than that. As for maintaining a level of curiosity, think of the brain as a muscle. Inactivity will cause it to atrophy while exercising it will make it more robust and perhaps help prevent dementia. Our thoughts have a biological basis and like any complex, chaotic system, small changes in one area can lead to large changes elsewhere. The human brain is literally the nerve center of our body and among its many functions are communicating, coordinating and regulating the organs and bodily functions. Particularly, it's in "control" of the endocrine (hormone) and lymph (immune) systems. Consider this: Has thinking about your own mortality made you feel depressed? That's an example of your cortex influencing your limbic system. Have you ever seen or read anything that triggered moral disgust? The part of the brain responsible for making us gag when we eat spoiled food is activated when we find something morally objectionable or unfamiliar. Has thinking about an upcoming deadline caused such anxiety that you feel pain in your chest or become short of breath? As a more apt answer to your question, consider the scenario of a drug addict purchasing their narcotic of choice. The anticipation they experience right before doing their drug is almost as powerful as taking the drug itself. People who do stimulants feel the need to go #2 right before doing the drug.
