Too bad that we are asking the WRONG questions!
It seems like we all google a question that we have, only to go through the results to find what fits the answer that we actually WANT! So what good is a search engine but to speed up how fast we get our DESIRED result - the WRONG answer?
Many people post, publish, and upload what they REALLY believe to be true, but ANYONE can do this. They "claim" to be the "authority" on something, or a "specialist" of something, when in fact, they are just a normal "Joe."
They will post about their PERSONAL experience (that may be ony ONE instance or experience) and give you "guidance based on the ONE encounter. (Whereas most professionals will NOT post their information, because they want your BUSINESS!)
So most of what you see, hear, or read on the internet is as reliable as the "know-it-all" that lives down the block, or the person in your office that is the "official spokesperson for everything".
The next time you have a bodily rash, or a wilting houseplant, or a vehcle that won't start, or even a need for investment guidance, don't worry about it. Just Google it, ...or ask your neighbor. The chances of getting an accurate answer is about the same!
And then go and ask a professional.
