It has recently occurred to me that people fear an excessive amount these days. There are rational fears, like driving near large cars and gangsters with daddy issues, then there are the every day fears. So many people complain about being afraid of missing a TV show, or being afraid of talking to a girl. All these are really the same fear- the fear of screwing up. What we fear isn't that not watching the TV show will make us miss out on vital information like what to do if some has a heart attack, and a loved one could possibly die in the near future because of you not sitting down in front of a glowing screen at a certain time of day, nor are we afraid that the girl we fear talking to is really a secret assassin that we might accidentally piss off on the wrong day and be killed. No, what we fear is missing out on the enjoyment that this show could bring us, or the possibility of a relationship. We fear missing out on the best life, or at least having a better one. You'd only be afraid of missing a show if you knew somehow that it was likely to be good, just like you'd only be scared of a woman if you had suspected that she might actually be awesome. In short, our fears are not present fears, but future ones, fears that might result in loss or failure in the future.
Human beings have a singular adaptive strategy that far propels us beyond the world of beasts, which is the ability to learn. We're not the fastest animals (though we can run ridiculous distances), we're not the strongest animals, we don't really have fangs and out claws are crap, but have the unique ability to learn. What defines an animals's evolutionary adaptiveness are not only its physical features and abilities, but behavior. A dog's fear response of tensing up and making its snarling bark is part of what makes it a dog. Humans, on the other hand, have the ability to change our behaviors over time, to an extent that is unseen in any other living thing. We can learn to drive cars and cook, use jackhammers and plant trees. These are things that are passed down the community, because humans form communities not only to birth, but raise children. This understanding, however, comes with a rather large caveat: it expanded the range of our fears. If you can now rationalize that 1. you don't have fur, so 2. you should wear a jacket because 3. the forecast said it would be cold later, then we can rationalize that a thin jacket would probably be inferior to a thicker one, and perhaps there would be a wind due to the incoming front so a jacket that's purely insulative would maybe not be the best choice. Neither would a jacket without a hood, but perhaps wearing hat and scarf would be just as useful. Well, this hat covers the ears and the jacket has a high collar, so maybe a scarf isn't needed. All the same, one should bring it because should the wind pick up or the temperature drastically drop, it would help a lot. However, if that were to be the case, one would want a thicker hat, but the one that you've got doesn't match the scarf entirely, or the outfit for that matter. It should be better to change entirely.
As much of a farce as this scenario is, this kind of thinking is more common than not. In fact, I would venture to say that nearly everyone has experienced some form of this runaway thought sometime in their life, if not on a daily basis. This future thinking is so different from the kind of thing that the limbic system is supposed to deal with that it doesn't know what to do with it, so it manifests in one way: fear. Stepping out the door now in the jacket, hat, and scarf, of your reluctant consensus, doubts start to creep back, making you fear that you've made the wrong choice. And physiologically, this fear manifests itself in much the same way as if you've just entered into a dark forrest- increased heartbeat, uncertain stride, protective body language, etc. These future fears have such a hold on people that we're always fighting through the future to be in the present.
What then should be done? Letting this fear control us, especially of something so immaterial, is nothing short of ludicrous. It's a terrible thing to give up living in the "now" for living in the "if". In all honesty, I don't know.
