Now, that's another thing that's...do you think that would be important? Or do we... I mean, I've seen some studies in mice where they claim it is, but mice have a very high metabolism. And so, there's a synergy there. But when you look in humans, it's not so important. Like, the exercise can still induce autophagy in skeletal muscle in humans even without being in a fasted state, but the question is like will you synergize more and... You can speculate, but we don't know.
