Well now, let's take that a step further... if mice age MUCH faster than humans and your postulate is that they won't live long enough to be affected, is that a reason NOT to do a study? Perhaps there is more than meets the eye in that very postulate. Perhaps they actually would be affected due to their "accelerated" aging?

That is to say, one cannot determine (read predict) the outcome of an experiment before one performs the experimant. I say, fry up a few rodents. That's what they are for.
