Given that we seem to have reached a point that medicine can cause the body to outlive the brain's shelf-life (eg Alzheimer's and the like), I'm not sure your plan is going to work out that well for you.
From my perception of death statistics for old people; it's diseases and cancer that may be said to kill, but it's lack of blood flow to the brain that kills.
I've read some pretty disturbing examples of how some people have their bowels rot due to the blood flow in the artery (arteries?) becoming restricted or even blocked from supplying the bowels the same way arteries in the heart are but it's not as apparent as it is for the heart.
Noted, however, I'd also like to defeat Alzheimer's by growing sub components of the brain one at a time and then swapping them out one at a time every few months. So over a few years I would have a new mind as well as a new body, as long as the spark of who I am can somehow leap from the old and dying components and migrate into the newer components, who I am, that spark that makes me ME will live on, in some way.
Sure, I technically wouldn't be "me" anymore, but technically I'm not me I was 10years ago, life is in constant flux. The technology in this article is the best chance I have at immortality. People, please devote more energy to this, it's important to me. I want to be around to see the human race become a space faring civilization, I want to see how we will deal with the 2nd law of thermodynamics where the energy of the universe runs down to zero.
If nothing else, this is at least a huge step in the direction of having the mind be the body's "expiration date". And eventually that can be fixed, too, I'm sure.
The societal impacts of immortality are somewhat scary to contemplate, though.
