"Social life and mobility are keys to quality of life in old age"
The article goes on to say that old people go to great lengths to stay active and connected, and use their well-seasoned brains to problem-solve issues of daily living at a rate that makes most younger people look like pikers.
In this article, they actually used the term "extreme lengths" -- obviously they haven't considered what it's like to be old. You simply have to cope, in order to have a life worth living, and your friends help you figure it out. Doesn't that seem pretty self-explanatory?
Nurses could have told them all that, plus a bunch of gruesome stuff about skin care, but study scientists pay even less attention to nurses than they do to patients. I'm just glad someone FINALLY thought of asking the only people whose opinion on "quality of life for the elderly" really counts.
