This incident sounds like a stroke, but I've been reading about Covid patients feeling 'normal' before their O2 saturation reaches critically low levels.

It might make sense to check O2 saturation as part of preflight IMSAFE checklist. If O2 is already low on the ground, hypoxia could happen at lower than normal altitude.

Is the Corona boogeyman going to replace the dehydration boogeyman?
