Eremitism
A TIL moment some weeks ago was that my outlook lately had a name - eremitism. Sounds cooler than reclusive.
I think eremitism is a spectrum with stoic renunciation at the extreme, and I find myself somewhere in the more temperate climes. Mine is more a slight reduction of social interaction.
Google trends for eremitism said it's only a 2025 thing (not sure something that has a hundred hits is a thing these days) with negligible blips earlier, and mostly from Kenya. Huh.
