3 years ago I tweeted that, and it went on to be, by orders of magnitude, the most-read bit of writing I've produced about the philosophy of time. 20 million views, 400k 'likes', newspaper articles, end-of-year Buzzfeed lists, some genuinely bizarre emails, and even being recognised while abroad.
Overheard a university student say “Arctic Monkeys were my dad’s favourite band when I was little.” The passage of time is relentless, unfathomable, cruel, and unforgiving.

Query for causation folk: correlations due to a common cause C are screened off by conditioning on C. So there’s a selection artefact due to doing this inadvertently – i.e., missing the correlation, by selecting subjects who share a value of C. Does this have a name? Are there good real examples?
