Could you imagine the psychological damage of having your adult mind shoved back into your 6 year old self? You’d be unable to relate to or even tolerate any of your peers, so say goodbye to any childhood friendships. You’d be unstimulated by the mountain of busy work in school and frustrated by all the topics you’d have to relearn. I personally would go through all of the procrastination troubles again. There are plenty of traumatic events that you would not be able to prevent or even affect. Nevermind that you are still carrying that trauma with you, you’re just trying to not re-live it. Develop any chronic illnesses? Maybe you can get treated quicker but you still have to watch your health decline. It’ll be a decade before you have any kind of autonomy to do any stocks or Bitcoin type stuff, unless you want to become some prophetic wünderkind. As far as I’m aware, mt gox was one of the only reliable places to get Bitcoin, until it wasn’t. I don’t know the day that it fell apart off the top of my head.
I never understand why anyone would choose the “do it all over again” scenarios.
I remember a phase in my childhood where I could only get Realplayer to open some series of anime that I was into at the time that I had downloaded.
