Medically there are policies in various countries that differ on the term 'dead' or 'clinically dead'. Various places have different standards of dead.

This has a huge effect on organ donation rates. For my medical emergency thank god I live in the US or my organs would have been donated already.

some places may have a policy for either 'respiratory arrest or cardiac arrest after x period' to be considered clinically dead. If I had been in one of those countries my organs would be in many different people's bodies.

I thank god every day that I was born in the US.

This article is quite fascinating, but the title is a bit misleading. The diver was about 100m deep. He was on the sea floor but arguably not "on the bottom of the ocean" (though maybe, by some interpretation)

what is the sea floor if not the bottom of the ocean?

in that case I too have run out of air at the "bottom of the ocean"

This is correct; scuba divers are trained to do a controlled emergency ascent while continuously exhaling, because your lungful of air at depth will last the whole way up, and the real risk is not running out of air, but embolism from overexpansion. The limiting factor in ascent (and therefore the reason for the recreational dive limit of 60 feet) is the risk of decompression sickness. If it weren't for that, a diver…

Recreational dive limits are usually set at about 100 - 130ft (30 - 40m) depending on the training standards in use.

The beginning certification level is 60 feet. You unlock the deeper limit after additional training, and it includes performing a three-minute "safety stop" at 5 meters. 60 feet is about as deep as you want to shoot to the surface from (and if memory serves the limit they give in training is 30 feet, or 2 atmospheres).

Question for the medical readers: a person dies when brain dies from lack of blood flow, right? So all those injuries, say a car crash where heart will stop soon. 1) Disconnect the head from body 2) plug it into a machine that supplies blood, etc 3) the body is repaired 4) reattach head to body. Overlooking the obvious trauma, is this possible? While extreme/traumatic, I think it could be more reliable as other facto…

We still cannot repair a spinal cord injury. A complete decapitation is a total spinal cord transection and more.

step 4 is pretty hard.

Just do step 1 in reverse.

someone tried to kill me for exposing them raping my girlfriend and the doctors used experimental oxygenated blood to save my life. I got really drunk the night i was assaulted because of a related incident. During the incident with my gf, her ex and i were trying to locate her after a party (we were in another dorm and she called us on a cell, not hers) and she recollected she didn't know where she was, she was naked, and that some males were holding her close not letting her go. They would only give her clothes after a sexual act was performed. We tried locating her but we were too late. Afterword, I and the girlfriends ex tried pulling the call 'metadata' but it was deleted or i was not allowed to access it.

I have a higher likelihood of suffering a stroke in my 30s due to the fake blood injections.

My roommate was paid to keep watch while the offender tried to suffocate me. While transported to the hospital i lost consciousness for a long time. The hospital pretended like they had consent to inject me with the fake blood. The hospital covered up the rohypnol in my system. The nurse there assumed i tried to slip a gril a roofied drink and failed. The college buried the report, blaming it all on me. My parents were shamed. My girlfriend ended up dating the offender for 2 years due to violent threats on family. The offender got away with sexual assault against me (buck breaking). The offender stuck his dick up my ass so I wouldn't tell anyone of the event (i am male and it almost worked). The only reason I survived is that I pretended to die (thanks burn notice) only for the offender to realize he didn't want to kill anyone. I had a brown-out of the events for about 1.5 weeks after. This will be my greatest shame for the rest of my life not trying harder to prosecute the incident.

So this may be the basis of cryogenics? If you just cool down in specific way, you can turn off metabolism and then turn back on again at later date?

Well not really. Cooling the patient down will give you a few hours at most under ideal conditions. Metabolism isn't turned off, just slowed down. If you freeze the patient the ice crystals damage the cells so much that revival becomes impossible.

Flash freezing (using liquid nitrogen to freeze something really quickly) is used successfully for smaller objects, such as frozen berries and frozen vegetables that you can buy at the grocery store. The Wikipedia page on flash freezing links to this [0] site with some more discussion. The Wiki page also says that flash freezing still can take a few hours, so there are still ice crystals created, but a lot less/smaller than if you just put it in the freezer.

Overall it seems it's just a matter of waiting for technology to advance to the point where we can very move a 150 pound 2-meter-tall 1-foot-deep object from 98 degrees to 30 degrees, and at that point the science fiction will become reality.

The polar station in Antartica is also quite inaccessible during winter. Winter-overs are proud of the fact that they are more remote than the ISS. There you can get in a Soyuz and be back in 90 minutes. In Antartica it might be a month before they can airdrop supplies, maybe four month until they can airlift you out.

See also: https://en.wikipedia.org/wiki/A_Place_Further_than_the_Unive... It's a great series about exploring Antartica, where the title came from the fact that it takes longer to reach Antartica than to reach space.

It makes sense. Antarctica is further away from almost every place on Earth than Space is. Sea level to space is closer than Manhattan to Trenton.
