Allen was well aware of the anomaly happening to him.
In the morning, he was full of vitality and appeared youthful, but by noon, he reverted to the appearance of a thirty-five-year-old. By evening, he would become an old man nearing the end of his life. He had sought doctors before, despite the world being small, there were still capable doctors who believed in the War God.
After being beaten a few times, the doctors admitted that this disease of "reverse aging" was extremely difficult to treat and they had no clues on how to proceed. They suggested he could apply for treatment on another planet, but Allen refused this proposal.
Never mind, it's not a major issue. In fact, from another perspective, it seems like he won't age anymore, and he has more time to read more books in this cycle of life.
