By all means, rely on them. I have no doubt they are reliable.You had me until you said experts are not truth. I have many experts who are doctors that I rely on. Maybe many is an exaggeration. (Didn't know that word had two g's... Guess I dont use it enough)
In any event my point was there are experts who know how to fix a heart. I don't number among them. I have some ideas... I'm sure lots of people do... I would rather trust someone who learned and trained how to fix hearts and has a track record of doing it. (Although that last point I might not care about if I really needed my heart fixed)
They are just not truth.
