On Tuesday, a few friends at my university told me that one of my flatmates during my undergrad years (having a body similar to the girl in this photo) passed away. Her boyfriend found her dead on Tuesday morning. It was estimated that she died around the midnight of Monday/Tuesday, probably just a few minutes after she fell asleep. Her heart probably stopped after an apnoea during sleep; her breath stopped suddenly and never restarted…
During the undergrad years, she was a runner and cyclist on the university athletics teams. She once fainted for a few minutes during a training session in 2017. But the ECG test indicated nothing abnormal then.
