There is the mistaken belief that one can recover from a Covid viral infection despite all evidence to the contrary. There is permanent damage to the body. It if more like children getting scarlet fever which can resulted in damaged to the heart. A friend's father who was very fit and did not drink or smoke, at age 32 had a heart attack and died in the lobby of a bank where he was planning to get traveler's checks for the family vacation.
My wife and I have avoided air travel completely. I cannot see sufficient reason to risk permanent damage to my body, and my lungs and brain in particular. If I became infected I would most likely avoid spending time in a hospital and acquiring some new additional infection, but the damage to my body would be something I would have to live with for the rest of my life.
I want to do everything possible to live as long a healthy life as possible and avoid high risk behavior that will jeopardize that objective. Fortunately my wife shares my desire.
