Nah, gravity is not that dangerous (unless you go too close to a black hole or a neutron star, if so then no dice.)
It's the ground the real killer... It's the contact with the ground that will kill you, not gravity.
All credit goes to the great Douglas Adams who has written : "there is an art to flying [...] or rather a knack. The knack lies in learning how to throw yourself at the ground and miss."
Simple right ?
Okay Mr Smartass, it's the combination of being accelerated by gravity to a sufficient velocity and then having your momentum stopped near instantly due to contact with a solid object, the ground in this case.
Due to the rapid deceleration the body experiences, the relevant forces on the body will be too much for your skin, bones and organs to handle, resulting in death.
So no, it's not the contact with the ground that will kill you, it's contact with the ground stopping you while you are traveling at high speed.
