Combo of height & way angle at which the body lands eg if you slap the palm of your hand hard against the water, it'll hurt, but if you cut the water with the side of your hand, it there's no resistance. Also, sometimes people hit their heads against pillars on the bridge, or rocks in the water. Sometimes the water is so cold it shocks the body & the person is momentarily unconscious which causes him to drown.
First off, the cliff diving bit, it depends on how high the cliff is. No matter what you jump off of, if it is high enough, it won't matter if it's water. You'll hit it just like it was a brick wall.
It's just law of physics. You're going really fast and then all of a sudden, you're not. Impact.
Pretty simple. Don't take those video games to heart.
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.
