It's incredible how the human brain works - while it's not healthy, they should learn to adapt, (and it's a bit stupid to live in fear of this virus) I don't blame your colleagues at all.
We are programmed to think that so many people die - not that the mortality is somewhere around the 1-1.5% for the average person, and if you look after yourself, exercise, don't eat shit, that mortality is likely to drastically drop down further.
We tend to look at the worst case scenarios. I know flying is mostly safe, but I hate flying and I'm scared of it. I do fly, and I know it's stupid to fear it, but I can't help it.
While I'm terrified, I know I have to get on with it because it's incredibly unlikely something bad will happen in an airplane. I wonder if the people who are terrified of the virus will live to think similarly?
Surely it won't be like this in 2025?
