I don't know much about physics, but I know that energy cannot be created or destroyed. So if this is the case, what happens to all of the energy stored inside, say, a person, if they were to die? Think about it, there's all sorts of like, emotional energy, it takes energy for all of the brain processes and such to occur, what happens to it all when the person dies? Could that be what a "soul" is?

I'm just curious while i was in elementary school they told us how bad pot is and everything. Now that i'm in high school it seems as if almost everyone does it. The people who do do it are still normal people, they didn't die after they did it, it didn't make them stupid or anything because some of the people who do do pot are smarter than me, does anybody else feel this way, are the things they tell you about drugs just supposed to scare u from not doing them???
