Nature magazine polled their readers on their use of "cognition-enhancing drugs," such as Adderall, that great booster of the chattering classes. Oh, let's just call them by their street names: Speed, people. Uppers. Bennies. Blues. Results of the poll? Readers are for them! Twenty percent have taken neuroenhancers like Ritalin, Adderall, or Provogil, seeing them as a perfectly acceptable way to focus and "stimulate concentration or memory." More proof that the modern world has shot our attention spans to hell.
