I am pleased that no traces of the lizzo flute discourse can be found here. Genuinely reflects well on this place.
I'm not gonna lie, my reaction was "Wait wouldn't saliva be bad on an old wooden flute, oh wait, it's not wood, OOOOOOH people are freaking out cuz she's black!"

@Jeast in my experience, wooden instruments are typically damaged by cold, dry conditions. That damage can happen pretty fast.
For moisture to be an issue you need prolonged exposure or actual liquid spilled on the instrument. I've repaired classical instruments - professionally for a time - and even a very old flute can handle being played as long as it is cleaned afterwards.
