The main thing is that there is not really any solid understanding of quantum mechanics at all why would you base your life on something that we don't really even understand that well.. all we know is that if you lower the temperature of biological matter, it stops rotting.. and we know that we are the information in the brain, we know the information once thought lost or unrecoverable after a period of time as technology advances becomes recoverable..

At least go to the permafrost of Canada up north and spend your last days there, Rick, because there are lots of animals recovered from the permafrost that are tens of thousands of years old.. don't overthink it, especially when you're talking about such a speculative field as quantum mechanics
