google-medlineplus challenge

The health topic I picked was longevity. When I googled it I got 25,300,000 hits, with the search taking 5 min. I came up with in the top hits: longevity, longevity/diet, a wikkopedia entry, and Northwestern Mutual insurance site (nmfn.com). Hits were dot.coms. No patient or self-help support groups. None of the top hits provided helpful information.
Medlineplus, on the other hand, provided useful information quickly. My question was probably a bit too broad for getting an overview, however, at least Medlineplus did provide that kind of information in the form of published articles. Thus, in future, I would start with Medlineplus!
