I think being 65+ and reading your Twitter feed/Ribbonfarm is a pretty strong malcontent signal—guessing not many people are looking to refactor perception at that point
When I'm 65 I'm going to be eating cat food and reading Emerson's *Journals*, Lucretius, and Wordsworth. Oh, and the New York Edition. At that age that's the only curious/exploratory that will serve, unless you're a numpty.
