history: Though I'm confident in my mental and physical resources I fear the worst for most people in my generation sometimes...especially in a hypothetical World War 3 scenario, or some type of global calamity occurring...every soft little punk wussy Millenial would just go to pieces
current: I'm pretty self-assured in my capabilities.  But sometimes I fear the worst for the majority of my generation who would have no idea how to raise a family, profit from their own sweat and hard work, have an organic conversation, or let alone survive a World War 3.
next: Well you shouldn't fear things we have no control over anyway. I'm sorry you feel anxiety over this.
