Yes, when there is a heightened risk of nuclear contamination in Europe because of a stray rocket in a war zone, we should tune out instead.
I think CS Lewis explained it well when the atomic bomb was created:
> In one way we think a great deal too much of the atomic bomb. “How are we to live in an atomic age?” I am tempted to reply: “Why, as you would have lived in the sixteenth century when the plague visited London almost every year, or as you would have lived in a Viking age when raiders from Scandinavia might land and cut your throat any night; or indeed, as you are already living in an age of cancer, an age of syphilis, an age of paralysis, an age of air raids, an age of railway accidents, an age of motor accidents.”
I have absolutely no way of impacting events in the Ukraine, even if I decide to contribute to a charity or try to influence my local member of parliament there is still absolutely no benefit to be gained by anybody (except perhaps the media) of me consuming this coverage.
I can however benefit significantly by avoiding news reporting that is going to continually trigger primitive fight or flight instincts and leave me in a high state of stress.
