George Church is suggesting that within 5 or 6 years age reversal might be possible. I think more money effort and focus should be placed on this effort. I am concerned that the religious and the elites will prevent those not in the small group $$$$$ from achieving improved lifespan.
George indicates they are working on 65 different tests in which they modify the epigenetic via crispr. The epigenetics are modified via crisper to have the expression more similar to a young cell. Thus the time clock in our cells is reset.
