Thinking about it does seem depressing, but at the same time, it wouldn't matter since your mind would completely be erased of any and all memory, skill, and knowledge of anything that you learned from your previous life.
Now I couldn't stand if I had to be born again WITH memory of previous life. I wouldn't be able to take that at all.
If everything gets erased of your mind, pretty much that doesn't equal to the death of the guy you were?
I mean, if i died tonight and reincarnated as a prisoner in middle Africa, i wouldn't have the same toughs or feelings.
Now if i died and get to remember all my past life's and chose if i want to reincarnate or do other shit that would be a little bit different.
