Help How high is high enough to be certain of death

[lostangel]

I was thinking of jumping to my death and was wondering if jumping off a crane that looks about 6 storys high will this kill me? Even if I don't land on my head but instead on my back?

I will say 6 story´s will kill you but it´s all about how you land, like there was even a football player who died some years ago after trying to make a backflip after he scored a goal he died at the scene because he broke his neck and that was just from jumping and landing on his neck.

So if you jump from 6 story´s on concrete I am sure you will die.
