"Many years ago, he reached the state of Fasting, I guess? As for now, I have no idea; it's impossible to tell. But his teeth fell out and then grew back again, the white hair at the roots turned black, now he has a full head of black hair, and there are much fewer wrinkles on his face."
"Is there really such a thing as the Fasting state in this world?" Yusuf Zuck was taken aback. Fasting means not eating, drinking, or sleeping, right? Are there really people in the world who can live without eating or drinking?
