P.S. to the article, I found Ellen Langer's 1979 study of particular interest. In this study she got a group of people (in their late 70s to early 80s) to live like they were living in 1959 for a week, this included having music, movies and books/magazines from the era, and the findings from this study demonstrated that many health related issues related to ageing started to reverse! e.g. improved flexibility, diminished arthritis, improvement in weight and even intelligence.
