Also, I find solace in the scientific fact that no matter can be created or destroyed. If that is true, then what about your soul (if you believe in that kind of thing). I was also reading about a study which stated that IMMEDIATELY after a person dies, their body loses 5 lbs. I don't know if this has any weight here, but it's just little things that have eased my mind over the years. Do some research on both sides of the arguments, it's pretty interesting.
But the truth is, no one really knows. For all we know, afterlife could be the greatest thing ever.
