What goes around comes around.
You have to take note of the expert advice but also look at your personal circumstances.Exactly this.
Modern logic seems to be:
I have never crashed a commercial passenger airliner. Trained pilots sometimes do. Therefore it's safer for me (not a pilot) to fly your plane.
I have never killed a patient on an operating table. Trained surgeons sometimes do. Therefore it's safer for me (not a surgeon) to perform your operation.
I have never misdiagnosed or given a patient the wrong drugs. Trained doctors sometimes do. Therefore it's safer for me (not a doctor) to tell you what meds to take.
Diet and exercise also advised by the experts but is a hard road for some so they are a bit chary about it.
I'll let you know how I get on, if I'm still alive in a month or so!
