My favourite comment on this is the following joke exchange:
Doctor: Your BMI is high I'd like you make some dietary adjustments.
Patient: BMI doesn't measure fat accurately for example professional Rugby players are marked as obese but aren't.
Doctor: Are you a Rugby player?
Patrient: No.
It's a good guideline. Don't let edge cases control your perception and let professionals do their thing with the tools they have -- they're aware of limitations that's why their professionals.
