The soul (might contain sensitive issues)

*might contain sensitive issues.. reader's discretion adviced*

We all know the word 'soul'.. most of the time its related to some religious thing, some 'spirit' or stuff like that. But if asked to define the word 'SOUL'.. not many could find the words to begin their sentence.

So anyway.. i was reading some CNS lectures.. and from what i understand, everything is related to the brain.. starting from emotions, sensations, perception, cognition, speech, movement... everything !

So now.. here's the question:
Once we die.. our 'soul' leaves the body rite? (correct me if im wrong).. so then our 'soul' is supposed to go to heaven/hell. If we go to heaven, its supposed to feel nice, and the opposite is true if we go to hell (correct me if im wrong again). So.. since after the point of death.. we aint got no brain no more.. this means that we cant feel pain/pleasure, we cant think, we cant talk, we cant move. So, whats so 'nice' about heaven and 'not nice' about hell?
Mayb for that matter, we've never heard of any religious literature talking about human riots in heaven or hell.. unlike on earth where we have all those gay-rights shit and anti-ISA stuff going around.. coz up there we all got no brains.. (down here we usually dont use it.)

Or mayb the soul just exists and floats around like the ice cream in my coke and wait till it gets dissolved by time?..

Hmmm... so, whats the 'soul'?.. and what can it do?
Probably it doesnt exist..
Like a Lego toy made from small little pieces that can be activated by electricity, humans are made from lil atoms that stack together.. and get activated by sugar to reveal stupidity.
