So another update about FIL. Because his body was weakened by Covid, he was more susceptible to the normal stuff older people need to watch out for when they recover from a serious illness. So he developed a secondary lung infection which resulted in apparently a whole lot of oxygen being delivered to their house. And he got dehydrated, and his blood pressure dropped, so he fainted twice which meant he was back in the hospital for 3 more days, and a lot more tests. He's home again now, with no additional medication or anything. Hopefully, this is the last of it.
