Instead of terminating threads that have potential for interesting conversation, could they be redirected? This is an example: https://www.physicsforums.com/threads/the-effect-of-little-sleep.816170/ I realize the issue is the variability in the result makes anecdote more probable, and we don't want responses to be perceived as medical advice. Could we (well, mods), instead: 1) Retitle the thread to focus incoming posters (e.g. "Short term effects of sleep deprivation") 2) remove personal anecdotes from OP. 3) make a warning post to keep the discussion generalized to demographics and minimize anecdotal discussion. We could have had some interesting discussion on the variability of responses in people with short term sleep deprivation and warned the poster not to make it about their self (thereby teaching newer posters how to have discussions here and making it clear we're not medically advising them in any way).
