There is no specific distance from which a person can fall and have it said they will survive or not survive. There are simply too many other variables that will dominate the factor of "distance." In 1971, flight attendant Vesna Vulović fell 33,333 ft (10,160 meters) and survived without a parachute. On the other hand 556,000 people died in 2013 from ...

It's not the fall that gets you, it's the sudden stop at the end. The most detailed data on the effects of large accelerations (or equivalently, decelerations) on the human body comes from research into spaceflight and aircraft ejection systems. There is a very detailed paper from NASA here, from which figure 5 (p. 36) is most useful. The summary is: it ...

16ft (5m) When rock climbing, you're pretty much guranteed to be landing on rock if you fall. When I trained in CSPS and EMP III, the magic number was 16ft (~5m). If someone fell from upright with their feet above that height or higher onto a solid surface, then they were an instant bag and drag, aka: strapped to a spine-board and rushed to the hospital. ...

You will want to look for a sun cream that is designed for swimming - don't bother looking for specific ingredients, look for the bottles that say they are for sun and swim. Usually in addition to the SPF they will have a rating or guide as to how often you need to reapply (eg every swim, or every two swims) @ShemSeger's comment is the recommended way to ...

This doctor's blog claims that: The median height leading to death is about 49 feet (15 meters), or about 4 to 5 storeys. 100% of victims die after falling 85 feet (25 meters), or about 8 storeys. Obviously, the 100% figure is incorrect as there have been individual people who survived higher falls. In any case, the height alone is not decisive. It ...

I knew a guy who was a medical examiner for the State Coroner. He dealt with a lot of people who had jumped from things. His rule was "Jump from seven, straight to heaven" ie 7th floor or more if you wanted to go right now rather than after a very painful interval.

There is no such thing as this certain height. You can fall from a chair, hit your head badly and be right dead. On the other hand, a couple of people fell thousands of meters (without parachutes...) and survived. Some things affecting the outcome of the fall are: Your posture (head/feet first), the surface (water, rock, snow, trees or bushes...) and ...

Depends on what's causing the cramps. In your situation, high stepping is what was causing your quads to seize up. The best solution there would be to slow down and stretch frequently. If you start chugging fluids you can actually give yourself more cramps, the kind that you'd have to simply wait out. I think electrolytes are the best way to get rid of ...

Its well-known to relate Cramps and Dehydration. So its obvious that you talked about hydrating yourself. But, in most of the situations muscle cramps can be stopped if the involved muscle is stretched. Be a bit careful about stretching at the same time. The safe stretching exercises that I opt for involves stretching ankle by pulling the toes up and ...

Generally a fall of 50-60 ft will kill most anyone. However, I had a friend fall of the back of a motorcycle that was not moving and he died because he hit his head on a rock, so go figure. A number of people have survived fall of 100-200 ft without substantial injury. There are three people who have survived falls of 10,000 feet. One, an airline passenger ...

The extract from a report linked below might be of assistance, and the report is well worth the read and should be quite accessible to those without a medical background. The American College of Surgeons' Committee on Trauma (ACS-COT) defines a critical threshold for a fall height in adults as > 20 feet (6 meters), as part of the field triage decision ...

As other answers have mentioned, there are too many factors to determine a fatal fall height. However, the rule of thumb for determining if there's a likely mechanism of injury for a spinal injury is whether there's a fall from more than 3x the person's height.
