The brain has 100 billion cells
(a trillion at birth) each with the ability
to make 50,000 connections.
Connections = 100 billion X 50,000 = 5,000 Trillion
If a brain connection stored
just a symbol (bit), the brain would be a
monumental humungous ( 625 Trillion Btyes ) storage capacity !
It could store 125,000 DVD movies.
But the brain contains the mind
which holds sense-data memories,
languages, skills, desires, feelings, ideas, meaning, intent, purpose ...
or our complete life story.
Perhaps, the "Last" spiritual process is to read all of our mind and DNA.
