Suppose someone has been declared dead. When do the cells of the body start to die?
When I see a dead body, are all the cells dead inside? (especially the ones from the vital organs)? Common sense tells me that not all of them are dead. Brain tissue may have already started died(according to first aid course, they are the most sensitive), but what about lung tissue?
I have no knowledge of this, but from what I know about plants, plant cells don't start to stop functioning until many hours later. I consider that "alive".
Respiration... how long does it take for cells to use up all oxygen? How long can a cell survive without oxygen?

It might take some 20 hours for all the cells in the body to die after "death".
But I think we would call a person "dead" after the brain cells die. It's probably the part of the body to which we refer a "person" to.
I think current resuscitation procedures are more of "helping the body fix itself". Hence, in the future, people will develop things that can fix the body.
I don't really think a few dead brain cells will end a human being's life. It may result in paralyzation of certain body parts, but I think it isn't so serious.
What about saving the brain as a first priority? Hook it up to some oxygen device to buy time so that the heart can be fixed by putting some implant in?
Hey, that's an alternative to cryogenically storing people's corpses so that they can be revived in the future. I think it is really a distant future before you can do that.
I think the next step in medicine is treating the illness known as "death". Well, we are certainly on our way to that.
I also suspect that younger human beings can be resuscitated more easily.
I actually really want to get into a faculty of medicine, because I like the library.
The possibility of people who live twice as long as they do now is actually quite scary. However, I believe it is necessary if we don't want a very old/incapacitated population, because I predict that the Stage 5 of the DTM will continue for the next few generations, unless women start learning.
Whoa, and that's another story.
