"If you get very fine, accurate, and inexpensive control over your genome, you can fundamentally chan..." — George M. Church

I don't think it is about stalling or curing: it's about reversing. Curing gives you the impression of immortality. Stalling gives you the impression that you'll be 85 forever, which is not great.

If we could take one of my skin cells and turn it into an embryo-like cell and turn it back into a skin cell, it has reset almost all of the developmental indications of age.

Reversal is something that has been demonstrated in a number of different animals in a number of different ways. I think that's going to translate into larger animals and humans. We won't know until we try. But we are trying 65 different genes in different combinations to see if we can reproduce the aging reversal that we've seen in small animals.

What dinosaur traits are missing from an ostrich? The ostrich has a toothless beak, but there are mutations that cause teeth and claws to come back to their mouth and limbs. You need to replace the feathers with scales, but there are no feathers on their legs and feet, so you just need to make its whole body like its legs are.
