Thanks for this, although I continue to be confused about this, in that while getting stem cells in you may help "set back the clock" (and who would not want that?), it leaves those newly implanted cells at risk for the same fate that befell their predecessors. I mean, the environment has not changed, so....

We know from the Canadian stem cell trial over a decade ago that the new cells ultimately succumbed to the same fate. I'm not knocking this, as I said, it might buy time...but it's brain surgery, too. Very risky, very expensive. Will insurance cover it? Will Medicare/medicaid? I wonder how many senior citizens would be deemed an acceptable surgical candidate for this type of brain surgery....

Not to be Eeyore, this is really interesting.
