Do you think your fears are rational? Do you think most people's fears are rational? What deserves our fear? Everyone has their own idea of what deserves fear. I think it is irrational to be afraid of something that would not have a way of harming you. An example of this would be having a fear of being attacked by a shark when you do not live close to an ocean. I think a lot of times peoples fears are irrational because they are things that are not very likely to happen.
