They hold you in place in the case of an accident. It's much safer to be held in your seat during an accident than bouncing around the interior while the car rolls, or worse, being ejected from the car during an accident.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
