What if I am in denial

What if I am in denial? In my personal experience, Death is usually extremely unexpected. No matter who’s. The actual moment is unknown. My brother has Covid. They were being so careful. In my mind I can’t believe that he would die. In fact I thought my black friends would die. Three of them all ages, even grandma. All fine. Three of them have survived. My brother? Maybe he just happens to have susceptible genetics? What if... he is that one statistic? I guess we will know in the next 24 to 36 hours. His wife is worried. She survived Covid.
......Update...........
He has sepsis., was treated intravenously, but was sent home after two days with antibiotics. He’s tired. Sepsis+Diabetes+covid
