If only there was a profession where knowledge, experience and continuous development are used to provide advice and care for individuals who may not have specialised in that same area of expertise.
I assume medical websites are somehow kept vague in order to steer us to pay these highly regulated professionals a fee for a visit.
The problem isn't information availability, it's experience and interpretation which is not something you can do on an individual basis 'on the side', hence the expertise requirement. If the subject matter at hand was as simple to deal with as "see X, apply Y, get result Z", then that would be great. But as this is not an exact science, such a method does not truly exist, and therefore cannot be made effective in a listicle on a website or other medium.
