The only thing we have to fear, is fear itself. In addition, we are also afraid of shark attacks. That's just common sense. Rabid bears might also be a concern. Attacks by predatory animals in general would be a broad category of fears that we would have in addition to the overriding fear of fear. There are also falling pianos. While this may not be as prevalent these days as it used to be when the 3 Stooges were working as movers, some vestige of the fear remains. Fear of the 3 Stooges is a little more difficult to accept, however. After watching cartoons, some of us have reported a heightened fear of being eaten by trees. The related fear of being accidentally eaten by a beaver who is eating a tree has also increased. Of course, we can't forget the fear of blood-borne diseases carried by mosquitoes, syringes, and movies on SyFy. When we also consider the fears of everything that does and does not occur in nature, the list grows a bit longer. When we add aliens to the mix, a host of additional fears arise. The fear of being taken over, enslaved, eaten, pulverized, or forced to listen to Kanye are extreme examples. Fearing intelligent robots, toasters, wood chippers, and DAWs has become more prevalent as well. In addition to this, there are clowns. Let's face it, those things are just not right. Mimes, politicians, crossing guards, librarians, jocks, mean girls, bullies, managers, lawyers, club owners, and Facebook friends represent a myriad of additional fears of man's inhumanity toward man. Add to this unreasoning fears, and this list has grown several pages long. The fear of the unknown, the dark, rejection, humiliation, the Songs forum, and dongles cannot easily be overcome by logic alone. There is also the fear of philosophers, poets, lead singers, and interpretive dance to add to the mix. The fear of death can be dulled with a steady diet of reality TV, but it resurfaces during the commercials.
In retrospect, I'm afraid that we have other things to fear besides fear. (I'll add that one to the list.)
