Given the current state of the world, do you fear your children may have to endure a cataclysmic disaster in their life time?
As a 17 year old, no because something will happen in the next 4 years probably.
I think it likely, but fear it? No.
I think we are going to have to deal with a disaster. They will live in the after math of it. Which will probably be worse then the actual disaster itself.
