I didn't take it to mean something that they didn't know answer. But as relative experts in the medical field, they considered it a good and valuable question.
I was contrasting this with keyboard experts who berated me for asking but know even less. The former are pro-science. They have studied. They didn't know. They valud the question.
Others knew less and didn't even see why it was a valid thing to wonder about. Instead of any scientific answer, they regurgitated garbage.
This reminds me of my aunt who calls me about random issues she is having with her Samsung tablet and then is shocked when I can't solve her problem when I "do computers" all day.
