But not for Victoria Cilliers. The 4,000ft (1,200m) fall caused by her husband tampering with her parachute resulted in several broken bones, but not death. Hers is far from being the greatest height from which someone has dropped and survived.

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
And so initially, when we hit the ground with our foot, this spring compresses and so the force increases quite a bit, and we have the first force hump. And then we have a rebound. So the spring relaxes again, our whole body moves up and we fall back into the spring.
At 40,000 feet its only 2.72 PSI. If outside air gets into the mask and is breathed, it contains one-fifth (20 percent) of the oxygen necessary for survival at 40,000 feet. The time of useful consciousness on ambient air only at 40,000 feet is 15 to 20 seconds.
