A bunch of stuff has been happening lately that is confounding until I find examples in my life which bring things into focus and help me understand, at least a little.
A lot of it is COVID-based. Because COVID is still a novel virus and we don't have a lot of data on the long-term effects of getting it once or multiple times we continue to get shots, wear masks based on risk assessments based on how crowded a location is and how good the ventilation is and generally take care. This doesn't seem like a big deal - it's very transmissible, I hate to be sick if I could avoid it and if I got others got sick...I would feel horrible.
MIL has COVID - she was sick enough to be bedridden for a couple days but didn't bother to let anyone know. FIL can't drive and doesn't cook so I'm not sure what they actually ate for the couple of days. SIL went to look after MIL. SIL is staying with a friend and not wearing a mask or isolating. SIL has recovered from a mild case of COVID already. All of them take a daily assortment of pills.
A friend had COVID and was bedridden for 5 days while the spouse had barely any symptoms. She also has health problems. She doesn't know if it would have been worse had she not been vaccinated and has no intention of getting any more shots because she doesn't like how she feels after.
