Harvard offers a very long, very thorough, and very research-based article about ways to prevent memory loss to readers at this web site. Giving us seven preventative steps (from exercise to not smoking to taking vitamins), each "step" is clearly explained and mini-steps are included inside each of the major ideas. I would recommend this site for those looking for GENERAL recommendations on how to prevent memory loss. On a negative note, I'd like to think that Harvard would be against pop-up windows, but for this site, that was the first thing I had to deal with (by closing).
