When we see data indicating these mice have a 5-year survival which is greater than the control (uh... or whatever the equivalent is since even healthy mice maybe don't live 5 years) then I too will be celebrating.
Since the maximum lifespan of a lab mouse is about three years, and the record is 5, you're maybe asking a bit much.
