The Ultimate Search

When I want to look up a web page I once visited, sometimes I can only remember a few words, an image, or a "feel" of the page.

Now imagine I had an MRI/brain scanning device as I browsed the web. Then, whenever I wanted to remember a page, I would merely have to think of it. The distinctive thought pattern would be detected by the MRI and the right page retrieved. Some day . . .
