the oxygen theory (Score 1)

I, personally, don't agree with that one. I'm not sure why, though, maybe partially just because...well...I just don't! Which brings me to a question. If our body is running low on something -- say oxygen, someone is being suffocated -- does it try to use the little it has where it is most needed (ie. the brain and/or heart)? If so, is it specific to certain parts of the brain? I am wondering why people who have experienced drowning, suffocation, etc. remember the event, if the little oxygen they have left is needed in more important parts of the brain then memory -- ie. keeping up with standard body functions, like pumping blood through the body.
