Wow. Now there is a story with a moral.
Panic prevents rational thought, people die.
It seemed similar to an eating disorder. Neither of them could be without their masks even after both were told not to wear them any more by their doctors.
The most similar thing that I have personally been involved with are people who decide not to eat anything other than meat and eventually start paying the consequences. One guy we knew started having cardiac and other problems; his doctor told him his diet was to blame. He of course knew better and even after his wife prepared meals for him that were recommended by a nutritionist and begged him to eat a more balanced diet he would not change a thing.
Before he got mixed up with the no/low carb high protein diet he had been very active and no more overweight than most other men his age.
Oh, yeah. In case you didn’t guess the guy died from a heart attack.
