  @mychemicalrxmance That’s an amazing question! I believe we have different fears because we have different biochemical reactions to things (e.g. production of adrenalin and cortisol when we need to run or under massive stress). Fear is a very helpful reaction to protect us from danger. If we didn’t have fear we may get into damaging or dangerous situations.
