The concept is sound but I call BS on your numbers. I remember seeing a documentary (on all sorts of animal abilities) and they held cats upside down (by their legs) and dropped from the height of the ceiling and the cat landed feet first. The ceiling may have been higher than 8 feet, but no way it was 3 or 4 stories...
But I can vouch from personal experience that falling 25 feet and landing on your side results in debilitating injury. (Wish I had been a cat...)

Cats falling from higher up have time to spread their bodies out and achieve terminal velocity at much lower speeds. They then have a much better chance of surviving the fall. At mid-level heights they can't do that and tend to get hurt.

At the cliff(50ft high) about 20 min walk form my dorm room their were 2 drunk guys that fell off about 7 years and walked away from it, but 2 years ago a young kid fell off and died.

From your source: "The study authors speculated that after falling five stories the cats reached terminal velocity and thereafter relaxed and spread their bodies to increase drag."
To which I say "Bullshit."
Then your source continues: "However an alternative interpretation which came out of internet chat[7] of the study would be that upon an excess of seven stories the cats experience a higher fatality rate which precludes the owner from bringing them in for medical attention."
Which seems a hell of a lot more plausible.

A cat falling at terminal velocity or anything close to it would make a crater, and would use up all 9 lives at once.

A skydiver falls over 1000 feet before reaching terminal velocity, but the authors speculate that a cat reaches terminal velocity in less than 50 feet? I speculate that the "authors" were drunk, mean spirited high schoolers tossing cats out of their mom's 5th floor apartment.

reno wrote: These are the exceptions, not the norm. The minimal chance of survival in such situations is so microscopic as to defy description, and I'd not want to use such events as justification to jump out of a plane without a chute. As a rule, anything over twice the person's height has a greater than 50% chance of major injury.(American College of Surgeons, Committee on Trauma, Guidelines for Optimal Trauma Care. 1998, revised.) So... once you get above 12 feet, you have a good chance of serious injury.
Thank you.

In my biostatistics class, this particular study did come up. They analyzed data, I believe from New York, and concluded that mortality rates declined after the fourth floor.
Why were we discussing this particular study in my biostatistics class? We were discussing sampling bias and that these researchers were biased in going to a veterinary clinic and recording these falls.

Where are you studying biostats? What's your major?

In reply to: he suggested jumping out of a 2nd story window instead of staying inside a house with zombies in it
It sounds like your friend needs to work on his zombie survival skills. No one prepared for an attack would get trapped on the second floor of a zombie infested building...

I was a philosophy major and FAR from a statistics buff. Hell, I don't really know how to do anything in stats besides percentages. I admit I am woefully ignorant of the vast majority of the stuff. But I know how to interpret some basic stuff.
I'm in my first year in med school and it is SCARY how many people are boggled by things like percentages, p values, the basic idea of why one would run a multivariate regressions, etc. Reading (even skimming) the results section of a journal article is beyond many of my classmates, who have to take the discussion on blind faith. Its really actually scary.

Fell 85 ft down Brown Corner at Stoney Middleton. It overhangs a bit so didn't hit anything until the ground. Only the last inch hurt. Got into the pose I had seen parachutists land in and hoped, managed a forward roll. No breaks but everything on my body was bruised, from soles of feet to shoulders and neck. Lost about 1/4 inch in height due to compression. Was very very lucky and restrained myself from soloing for a long time after that.

From the view point of a paramedic, if you were to fall from a height of three "body length" or greater, i.e. three times your own height, we automatically assume that there has been spinal injury and treat for it.
Now, we are mostly just covering our asses by doing this, but say the average adult male takes a fall from a height of 18 feet (6ft x 3) I will be packaging him for transport wearing a c-collar and laying on a back-board. Yet I have treated people for falls of 2-3 feet who had broken arms and/or legs...
It all depends on the way you land...

This was way back and I felt better after the 1 mile walk to the public phone. I did check myself out for strange pains and 'numbness', which was the practice in those days. Most amusing thing about htis is that one of the people I was climbing with that day broke his ankle trying to jump over a very low fence. Still work on the principle that 'shit happens' and don't get too worried as you can do real damage falling out of bed.

I had a friend break his leg while standing on the ground.
He tripped over the trailer hitch of his truck while putting some groceries in the bed. He fell on the ground, thought to himself, "someone could get hurt like that", tried to get up, and that's when he noticed his tib/fib was all floppy and bent.

[quote "dancesonrocks"]I like the replies so far.
[quote]Not really a fair question. Too many variables in the equation. People can break bones from falls that are very short. Then you have situations where people fall from 40 feet and walk away without a scratch. Narrowing it to landing on feet may help.[/quote]
Consider the question narrowed down to landing on your feet, also assume that this person does not have abnormally bad luck and is otherwise of a sound body.
The situation I'm sure is fictional so it's not something that will be tested on live human beings; however, I think he wants the fiction to have a basis in fact.
I gave him a preliminary answer of 25 feet but told him I'd try to research the topic. My next step is asking a few doctors I know, but I wanted general feedback from climbers as well.[/quote]
in theory, a 20 foot fall will generate enough force to cause damage to internal organs that will cause death. but, i've watched someone take a 35 foot fall and, from what I was told, he was climbing a few weeks later. he landed flat on his back on a dirt path.
