Lately my father was in hospital and they did a lot of exams. But from a particular doctor I learned that a particular test/analysis/exam only makes sense in two circumstances:
- When there is a therapy indicated on a positive or negative result.
- When there is scientific interest in knowing that detailed information.
This is a good rule to avoid exaggeration of analysis.
And you can widen this idea in the way that it does not make sense thinking of something if there is no consequence whatever the result is. Keeping this in mind frees you from a lot of "spam thoughts" and reduces your "information overflow".
