There seems to be a huge number of fields-of-expertise that potentially have bearing on my life or work. E.g., urologists, transmission repair techs, indoor air quality experts, sleep therapists, house painters, early childhood education consultants, therapists/counselors, sports trainers, physical therapists, housecleaners, etc.
In my experience, most of those fields have practitioners who are sure they could help you avoid future problems; you just have to hire them to see the benefit! Or at the very least, invest time in helping them understand your particular situation so they can give more detailed advice.
I could easily believe that most of them are correct, too. But each of us, even in a business setting, has limited funds and time/bandwidth to deal with such specialists.
In my post above, I was trying to say that knowing which of these many specialists one should have engaged with isn't always clear ahead of time. E.g., maybe I didn't need to bring my car to a transmission repair shop, when the only real problem I'd have in the near year is back pain from poor sitting posture.
