When you use the Advanced Search tool on google.com, you’ll have more chance to find exactely what you want. There, you can choose the websites that you want to learn with, the words that you don’t want to appear when you search and among many other things you also can write a website to be some kind of example for the next search. As an example, we had to search for the words “atlantis”, “waterbury”,  without using the Advanced Search tool and with it. When I first searched, google.com showed me around 47,600,000 that actually matched with my searching information. As soon as I used the tool, 9,100,000 pages were shown.

Because since we are talking about health you have to “walk in the line”

After all those hints, I’m sure you know that my element is the…
