Sorry for your coworker but I am guessing they were not the picture of health?
Let's be honest, most the people that die from COVID are already on their way out. I believe that when we look at the yearly mortality rates or even average the mortality rates for 2020 and 2021 it will show a marked decrease in deaths from heart disease, diabetes, cancer, compromised immune systems, and old age.
That's because all those that should have died from the aforementioned diseases just died of COVID instead. Did COVID kill them a few months, perhaps a year, sooner?
Probably. But we are destroying the entire world for these people. If such people need extra precautions, fine.
They can live in an isolation room and wear N95 masks until this is over.
