Depends on how this works. Do I wake up in my younger body, in my previous situation? Do I still remember everything I know and remember now?

Or do I just appear as I am right now, in the past?

Because we've gone back, the money is kinda irrelevant in some cases. I would whoop out $3,650 or more out of my savings to go back a decade or more. I would give the rest to my family in case that timeline carries on, whatever is left is irrelevant to me since in the past I had $0. I'll have to make it again.
