Why do we fear fear?
same reason we love love.
essentially, if a verb and a noun are the same word, but we don't verb the noun, then it doesn't make sense. we hate hate. we envy envy. we loot loot. you get the picture.
It's a survival mechanism. If you didn't 'fear fear' you'd be much less likely to survive long enough to reproduce.

Eveybody always says I dont want to do something cuz it always sounds scary. Why are we scared of being scared, and then why does fear affect us so badly when we're expierencing it?
