Please correct me if i am wrong. As per MWI,when an observer open the box,schrodinger cat will be alive in one world and the same cat will be dead in other world. If we replace the cat with human,then the dead human and alive human will be different worlds.so,my curious question is does this mean even for normal death after we are old,the dead human will be in one world and the other alive human will be other world? so MWI says that there is life after death in other world? since we are in one world,we are able to see only the dead human and couldnt see the alive human who lives in other world?
