I agree. I purposefully watch and read the absolute minimal amount of media and news however my MIL LOVES the news and media, and we view the virus very very differently.
So you're saying your MIL keeps abreast of current events and likes to stay informed, and you don't, you'd rather be in blissful ignorance (don't mean for it to sound that harsh but I cannot think of any other way to word it at the moment)? Your MIL is well-informed so I guess that's why she views the dangers of the virus very very differently from you. I think those who watch and read the news are much more informed and more likely to take this seriously.
I am definitely the cup is half full whereas she is the cup of half empty
Or maybe she is simply far more realistic because is informed of the facts? Being optimistic is fine, and is a good thing. As long as you are being realistic and not running away from something you don't want to face.
If anything, I genuinely feel people are not taking the threat seriously enough and are failing at evaluating the serious risk. To suggest 1000 people die in car crashes in the UK per week, which is what the statistic you posted says, is quite clearly absurd. Also, you cannot compare car crashes because car crashes cannot be 'spread' within the community, it is not a communicable condition. The risk of Covid is very serious, it is more communicable than the flu, the risk is much higher than a car crash, and it's spread and impact is much, much greater.
I think people are making an active choice not to believe scientific reality, and avoid watching the news because they don't want to face the truth themselves. It's a protective measure. If you are not aware of it, it can't hurt you. That kind of thing. The rising infections are proof we simply are not taking this seriously enough, and our ability to evaluate risk is very sloppy and inadequate.
