&gt;<i>but for most people in first-world countries: Running: Specialized shoes and gear (...) Penmanship: Specialized quills and ink</i><p>&quot;Most people&quot; in first world countries hardly ever run.<p>The official statistics I&#x27;ve seen put &quot;joggers and runners&quot; as 17-18% of the US population, and their definition includes all the &quot;people who went jogging or running within the last 12 months in the United States&quot; -- so in reality, much much less, especially after school&#x2F;college age. This makes those irrelevant for the 80% and more. In most first world countries, which don&#x27;t share the US obsession with jogging, that&#x27;s substantially less.<p>As for &quot;Penmanship, quills and ink&quot;, that&#x27;s not even a thing for the overwhelming majority of the population. At least not since 1950.<p>And &quot;making electronica&quot;? I happen to do that, but I can count on one hand the number of people I know who even know what Roland or Ableton are (apart from collaborators etc).<p>So, I&#x27;d hardly call this list representative -- if it said &quot;urban hipster&quot; maybe, but the &quot;for most people&quot; qualifier is totally bogus.
