A backup in case of failure or something. I have nothing to lose.
You are completely missing the point here. Unless you're trying to fuck with everyone right now, you're delusional. Do you comprehend what you're saying right now? There is no way to be able to pick and chose how your brain will be damaged in the event that you die and lose oxygen, and are then brought back. Hypoxic brain injuries occur when all of the cells in your brain are deprived of oxygen and start to die off. They do not die off in some nice controlled fashion, it is completely and utterly random. Hypoxic brain injuries range from so mild it's hard to even tell (in my case I just have a shortened attention span from SN and I developed tics from failed partial hanging) to so severe that the person is no longer able to breath on their own, these are the cases where the plug is pulled. Anywhere in between that you can lose your ability to talk, to understand language, your personality can be completely changed, you can lose all of your memories. Or you can become a vegetable but kept alive and have to be 100% dependent on others and bed bound for the rest of your life.
To believe that you are somehow different that this and you will somehow become a genius by dying and coming back to life is simply incorrect. This is not going to happen. This is not a backup plan. And you need to open your eyes and realize that if you think surviving death is going to make you some prodigy then you are simply delusional.
