I mean that the physical information which defines - or alternatively is required to reconstruct - a human mind is not strictly localized in space to the confines of a single brain.
Using the hardware/software analogy, the brain is the hardware, the mind is the software, but the mind is distributed software: each mind program runs mainly on a single brain, but it also has partial cached copies distributed on other brains.
For example, if two people spend a bunch of time together, they are going to have many shared memories. Later if both die and the brain of one is preserved, the shared memories are useful for constructing both minds. With many preserved brains, you get multiple viewpoints for many overlapping memories which allow for more precise reconstruction.
I'm a little disturbed by the thought of reconstructing my personality from others' impressions of my personality.
I wrote an article about the process of signing up for cryo since I couldn't find any such accounts online. If you have questions about the sign-up process, just ask.
A few months ago, I signed up for Alcor's brain-only cryopreservation. The entire process took me 11 weeks from the day I started till the day I received my medical bracelet (the thing that’ll let paramedics know that your dead body should be handled by Alcor). I paid them $90 for the application fee. From now on, every year I’ll pay $530 for Alcor membership fees, and also pay $275 for my separately purchased life insurance.
