I would have cooked the salmon longer...I am so afraid of poisoning my family that I overcook everything:))

As for the article about COVID19 and early onset dementia: Inflammation is the hallmark of COVID19, and inflammation has long been associated with dementia. Any disorder that causes inflammation, particularly inflammation for an extended period, is likely to be associated with an increase in early onset--or any kind--or dementia. See this article, for example. I take an interest in this because I have an chronic autoimmune condition in which inflammation is the dominant characteristic. The challenge is a balance between treating the inflammation with drugs that are not good for me, and allowing the inflammation to persist. With medicine, it's always a matter of choice (if we are lucky), isn't it?
