"[...] extended the cellular lifespan of human skin and lung cells by more than 50%"
If we assume that the effect is the same for all types of cells, it follows that the life is extended by 50% (when keeping "all other factors" constant, as usual).
That's not a safe assumption.
It has to also down-regulate cells divisions, else it could be quite problematic.
