Anthropology. That's why I'm here. == [You joined philosophy to
  learn about anthropology?] == As part of anthropological
  studies. Subcultures. I always learn a lot about myself in the
  process as well. === [Then why do you respond to so many
  nonanthropologic posts? You can learn just as much about
  yourself studying astronomy] Been down that road already long
  ago. Got as much of the Universe in my head as I want for now.
  Philosophy I avoided for decades. So, I learn about the culture,
  its heroes, its people and followers and how they think, and I
  even have figured out places where I would and wouldn't stand if
  I was a native. === [ lol "done genetics" - You say that as if
  you learned the field. It's not that easy. Are you aware of all
  the new epigenetic research going on?] Well, I'm aware of DNA
  methylation and the like. I keep tabs on everything I research.
  I don't abandon them. But what I mean is: I study something with
  EXTREME intensity, barring EVERYTHING ELSE and then one day, I'm
  done. I look around at what I've learned, and I'm satisfied that
  I've learned the bulk of what I want to. The rest is filler and
  the occasional surprise. But I always keep tabs on past studies
  to see what's new. === I had a particular fascination with this:
  [1]https://en.wikipedia.org/wiki/Chaperone_%28protein%29 which
  held my fascination for longer than it should have. Protein
  folding is an area I can get mentally sucked into VERY VERY
  quickly, ever since participating in the Folding @Home project
  10+ yrs ago or whatever it was.
