I don't believe in the ''spirit''. History coupled with psychology would tell you that as we began to show compassion or were stricken by grief over our fallen brethren we became somewhat religious in wanting to believe there was something after our stay on Earth. Physics would probably say that there is no action in decay that leaves anything that we do not already understand in its midst. Also beyond just trying to find the stereotypical ''ghosts'' named in lore and portrayed in media for all its myth and so-called principles(which is just ridiculous). I say go ahead, many facts have been found looking for fiction. That is if you wish to shyt your life away. Thousands of people, probably millions if you count people doing it for profit ARE looking for ghosts as I type (specially since its dark out and that's when they come out, on the east coast, still too early for ghosts elsewhere) and they will NEVER..well presumptuous of me to say never but at least not in their lifetime, will they ever find definitive (acceptable by all of the scientific community) replicable proof of GHOSTS.
When I die, my residual energy or torn spirit, which is trapped in purgatory or on earth, due to my lust for woman, will haunt this forum forever due to my lust for woman and will make comments like: nice tits! shake that ass! and several cheese pickup lines addressed to random people whom may or may not be female.
