People in their early 40s tended to get very sick with COVID, and sometimes got permanent lung damage. Only a small percentage died, but a lot more died than people under 30. I did notice that roid users had worse outcomes, so that could be a bad thing for Chrissy.
However, Omicron is a lot milder, so Chrissy probably isn't going to kick the bucket from it. However, if he vanishes for several days, we might know why.
