Geoff Marshall explains a running gag about London Underground stair signs claiming that the climb equals 15 floors, regardless of how many steps there actually are.

Stuart Halloway argues that simplicity is objective, with a definition and etymology useful to programmers, rather than a subjective buzzword. He shows how this view informs Clojure's design and how to make programs simpler.

Dr. Sarah Hallberg argues in a TEDx talk that type 2 diabetes can be treated and potentially reversed through diet, especially by restricting carbohydrates. TED flagged the talk as outside its guidelines and warned against taking it as medical advice.
