The usual caveats apply to results from testing in mice; it might not be safe in humans, and it’s generally years of clinical trials before any human treatment becomes available.

That said, I wonder why humanity doesn’t put much more effort into research like this. The birth rate is rapidly diminishing in most Western countries. The 21st century will be, for the first time in human history, the century of the old. Historically that has meant burden, but it needn’t be if research like this leads to the results it promises.

Are telomeres considered to be a “cause” of aging, or just a “hallmark”?
