"Cough cough!" The old man suddenly covered his mouth, coughing violently, the nursing staff on standby hurriedly stepped forward, gently patting the elderly man's back.
After some time, the old man finally stopped coughing, gasping for air.
"I'm old, so old, no good anymore." The old man shook his head, then returned to reading his newspaper.
However, after just a short while, he started coughing violently again.
"Commander, how about taking some medicine?" the nursing staff whispered gently.
