Cryonics. Hopeful stuff or people wasting their time?

Of course, extracting memories seems like a stretch although primitive attempts are being made at the moment to do just that by using MRI scans.

But you don't just see things in dreams. I poked my dead father in the chest in a dream to see if he was real. I felt his shirt cloth (probably bedclothes). The "retina" of the mind might just be the whole cortical homunculus.

They don't freeze people. When you are put into cryonic stasis, you're not frozen, you're vitrified. With this process, your cells will not explode /

No tiny ice crystals knives going Jason Vorhees on a small scale.

I wonder if artificial blood cocktails can also be vitrified?
Maybe you could still think--with everything superconducting?

Well, keep in mind that you're only placed in a cryonic state once you have been declared legally dead. There is so much time for their teams to arrive, pick you up (doing a temporary stasis until they get you to their facility), and then begin the process. You are legally dead, but you have not achieved information death, which is the point where you, as you, cannot be recovered.

It's the flip side of Pascal's wager.

Not necessarily, but I do consider it a feasible option.

To have a chance to pull it off--having the fluids of the brain replaced with something that can vitrify may help--something like the clear fluid I saw a rat breathe in the old Discovery Channel broadcast BEYOND 2000. Do it before death--when young.

If nothing else, future history will appreciate you for being the best preserved mummy ever.

That's liquid breathing and the US Navy has experimented with that with divers but it's never been that successful. They even used that system as an idea in the movie The Abyss.

It is rather odd because when you are in the womb you are breathing liquid but somehow once we are born we lose that ability..

Fetuses don't breathe in the womb, do they? Don't they get their oxygen via the umbilical cord? There might be some oxygen dissolved in amniotic fluid but it's not used for respiration as far as I know.

The umbilical cord supplies nutrients..... I'll have to look this up to be sure. Hang on.

OK I was wrong about the breathing. The baby does appear to make breathing movements but no oxygen does come from the umbilical cord.

From here:
http://www.beginbeforebirth.org/in-the-womb/fetal-development

The fetus does not actually breathe in the womb. The mother breathes for the fetus, and essential oxygen is passed to the fetus through the umbilical cord. The fetus does make breathing-like movements though. These begin at 9 weeks of pregnancy and allow the fetus to practice this breathing movement. This means that when the baby is born, he/she will be able to breathe straight away.

and this surprised me:

Eye Movements

The fetus begins to move his/her eyes during the 14th week of pregnancy.
Complex movements, similar to our eye movements are present by the 24th week.
In the last third of pregnancy, rapid eye movements have been seen in the fetus. In adults, these occur when we are dreaming. Perhaps the fetus is dreaming too.

Hearing sounds

The fetus begins to respond to sounds at about 20 weeks into the pregnancy. To begin with the fetus only hears low noises, but as development continues he/she starts to hear higher pitched noises too.
Louder sounds can make the fetus startle and move about..
The older fetus is able to discriminate between different voices, languages, and even individual speech sounds, e.g. “BABI” and “BIBA”.

A newborn can recognise music that he or she heard in the womb.


Urinating, drinking, and tasting

The fetus starts to empty his/her bladder during the 10th week of pregnancy. Urine is passed straight into the amniotic fluid, the protective fluid surrounding the fetus in the womb. About five weeks later, the fetus starts to drink this same fluid.

So, while in the womb, the fetus is exposed to different tastes through the amniotic fluid. The fetus likes certain tastes more than others, and will drink more amniotic fluid if it tastes sweet.

Drowning in salt water is apparently different from drowning in fresh water.

With fresh water, you can die from the tissue damage to your lungs even if you're rescued.

Fascinating.

OMG.......... That is interesting indeed...... I thought it would have been the other way around with the salt burning lung tissue....

It's a very bad idea to swallow seawater, of course, as its salinity is about four times that of blood.
