I'm not sure that I have exactly the same definition for fear, but much of that is reasonable enough, as far as I'm concerned. I do think that fear can be bad, even debilitating. Fear can also cause stress, and extended stress can shorten your life. I don't think it is likely to kill directly, but it can shorten your life...and certainly make it worse.

When it comes to COVID, though, I'd say that there isn't enough fear, at least not in the US. People are acting like it doesn't exist, and plenty are dying from it. That's not an excess of concern, let alone fear.
