Jumping off tall things

no....if you jump high enough you will exceed terminal velocity and turn into a human fireball

You need to learn the PLF which is the best way to land when equiped, you let your legs go under controll and roll out side ways as you go to ground.
Supposed to lessen the chance of injury. That said as many as 10 % in a drop will probably be injured in one way or another.
Its not quite landing on your feet.
We drop from 15-20 foot walls but land bith feet first then bending at the knees till you can use your hands on the floor to further controll your landing.
