Not in five years, maybe not in fifty; this is so absurdly over-optimistic, it's not even funny.
We know SO LITTLE about how genes actually function to produce, well, you, the idea that we can, within five years, figure out which genes are "responsible" for aging and turn them off/around is ridiculous. The amount of feedback looping going on, even if we knew which genes produced which raw proteins, is so twisted that even figuring out the protein synthesis process itself requires super-computers, much less figuring out how all those proteins interact with your body.
We heard all this very same talk when the first Human Genome Project results were released. Please tell me what grand advances that has brought us, other than a few diagnostic tests, and some treatments for a couple rare diseases.
