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.
I've also heard things about how, for example, simply walking regularly for exercise can sometimes be more effective than chemotherapy.
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.
The societal impacts of immortality are somewhat scary to contemplate, though.
