Well… my personal experience with Covid-19 is that it sucks getting it. But, it sucks getting a flu also. Sucks getting a cold, really.
Me and my side of the family are all into sports, nature and healthy lifestyle. I train since I can remember, my father also. My mother is into cycling. Even my grandmother (88yo) was surprisingly vital for her age. We all spend a lot of time in nature. We have absolutely no medical issues; no heart problems, no high blood pressure, no history with overweight/obesity, no alcohol and no smoking.
Wifes side of the family are… well, her father takes his car to go his neighbour that is 200m away. They were never into sports or practiced what you’d call a healthy lifestyle. They all have medical issues, are a bit overweight and overall in poor shape (excluding my wife).
And yet… my family (including myself) all had serious problems with fever, high temperature, pneumonia, loss of taste and smell, headaches and eventually my mother and grandmother ended upo in the hospital. My mother is still recovering and has a hard time breathing when she’s active. I can feel the lack of “air” when swimming or doing conditioning/cardio. Grandmother passed away.
Wife’s fimily had no major problems, few days od elevated temperature and some random ills. Her brother and sister had no symptoms. Her grandfather (88yo) recovered in no time.
We all got Covid-19 from the same source, none of us were vaccinated and we all tested positive.
