Alice acted normal as she walked over. She started the usual series of tests on him to measure his blood pressure and temperature. Youyou was very cooperative and allowed her to use various instruments to measure him. However, his expression was indifferent, as if this were a routine matter.
Seeing that he was calm and collected, Alice asked, "Are you still having palpitations recently?"
"Occasionally."
He spoke few words, and never used more words than needed. He did not talk much, and probably apart from him, very few others could stay on such an isolated island for a few months without a mental breakdown.
Humans are social animals and are used to living in groups. The isolated Youyou had only Lisa with him. However, both of them were the silent type and seldom talked. Occasionally, when Lisa would try to talk to him, Youyou would put the conversation to an end with just a few words.
