Life is like electricity inside a computer.... either the switch is on and you have energy or not..... batteries inside the computer count as energy....
The RAM is volatile memory... if you are lets say writing a letter in WORD (without autosave) and the computer is turned off then everything you typed is gone....
When we die (the switch is turned off) then all the data in the brain dissapears...if you turn the comp off and on again then you have to re-type the whole letter again..
So lets just say that in fact you die and then come back to life.....you would not know what happend because you lost all of the knowledge you had because you died..... and if you remember everything then your didnt really die and your data didnt go anywhere... and if you lost some energy some of the data might be scrambled....
how does aperson interprets that white noise?..... oh yeah after life experience....
nde are nothing but glitches in your RAM. period.
