Richard Feynman wrote about how when his wife got sick he figured out that she had TB, but because he was very young and a physicist her family and their doctors ignored him and his diagnosis. He acquiesed and did not push, which he later regretted.
He said that only after they had tried many other approaches and wasted time did the Drs come to the same conclusion, but by then it was too late for her.
At that point her realized he was much smarter than regular MDs and never took their word as gospel from that point on.
That story stuck in my head as my friends and family have had medical challenges.
