When can we expect a news article telling people scientists advise not to wear parachutes?

This is almost certainly survivorship bias[1]. Only middle-height cats that might theoretically survive are going to be taken to a veterinarian; the cats that fell from higher heights were not included, because they were "obviously dead". Which makes "high-rise syndrome" an example of the exact type of bias discussed in this paper. [1] https://en.wikipedia.org/wiki/Survivorship_bias#In_cats
> Strangely, cats that fall from a height under 6 stories have more severe trauma than those that fall from over 6 stories. So, the theory is, if a cat falls from a height above 6 stories they either have less severe injuries or are just dead so the owner just doesn't bring them to the vet?

>>6 stories they either have less severe injuries or are just dead so the owner just doesn't bring them to the vet
I would guess that at that height something must've broken the fall such that the cat suffered almost no injuries. I really don't see how the cat would survive the fall otherwise.

Why do people use parachutes then? I felt like I'd like to have a parachute jump experience one day, do you mean that would equal jumping without a parachute (guaranteed death)?
It’s not guaranteed, there’s numerous cases where someone’s parachute malfunctions and they land with only broken bones and bruises.
I know but I have chosen to simplify the idea as the chance to survive (and recover your health to the level at which you won't regret you have survived) is negligibly small.

#65I think this is like the medical research paper version of the famous RFC for IP over Avian Carriers.

It's like when someone says something funny, then another person follows up with a witticism that basically repeats the same joke... Like someone makes an inspired pun and some dude immediately exclaims "LITERALLY!"
They did an actual trial here though
Also, the one with the trial was just published, while the funny one is from 2003. Maybe this is immediate in sea turtle years?

That's awesome, thanks! So is this: https://tontine.com/
I can't tell, is that a real site or a joke?
It has to be a joke as it is illegal in the US.
Edit: Upon further reading, seems like someone is actively trying to make this happen.

#68A coworker of mine once made this proposal. 5 of us would start a company. The company would buy key man insurance for everyone, then go on a company team building trip. On this trip, we'd all skydive, but one of the 5 parachutes would be non-functional...Profit! This coworker of mine soon after left the company by storming out of the meeting room and slamming the door, then took up playing online poker for a living.

There's a short term group loaning 'game' in Cambodia called and based on Tontine, which I would guess comes from the French influence.
The game is played by groups who agree on a monthly stake. Each month players offer an interest rate they're willing to pay (more like a tax), the highest rate is awarded the collective pot, less the interest which is redistributed to the other 'living' players.
Players who have already received the pot are 'dead' and do not collect their share of interest in future rounds (meaning they must pay the full stake). Once everyone is dead, the game ends. Some will have come out ahead, others may have been able to get a lump of cash when they needed it

Will jumping from high enough without a parachute ever decrease the odds of death than they the odds of death at a lower altitude?
Not that I know of. Maybe, if you jump from high enough that you pass out due to lack of oxygen, and you land in a manner that benefits from you being a ragdoll vs an actively bracing person, then it could help, but that seems unlikely(you'd probably also wake back up before you hit the ground, as I've heard stories about this happening to WWII pilots). But overall, I believe it is better to be conscious. If you are…
First you must find... another shrubbery! Then, when you have found the shrubbery, you must place it here, beside this shrubbery, only slightly higher so you get a two layer effect with a little path running down the middle. ("A path! A path!") Then, you must cut down the mightiest tree in the forrest... with... a herring!

#70> PArticipation in RAndomized trials Compromised by widely Held beliefs aboUt lack of Treatment Equipoise (PARACHUTE)
That has got to be one of the most torturous acronyms I've ever seen. That's a bit of a stretch.
