Mice have cures for everything, doesn't mean anything. There's lots of "cures" for them for different diseases. It doesn't translate to humans. I'd take a very skeptical approach to this anti-aging thing since it has only been done on mice.
1. Like I already said, sometimes mice studies translate to humans sometimes they don't. Since you say "It doesn't translate to humans" I guess that means you're saying it never translates to humans and the scientists (the people who should know) disagree.
2. The anti-aging thing has not only been done in mice. It's also been done in human cells in the lab and on some human so far. More human studies are imminent.
