What is this?

I'm Paul Nunesdea, PhD, CPF — a facilitator, researcher and intensive AI user. I spend much of my professional life helping people think together in complex settings, and much of my private curiosity wondering what increasingly intelligent tools are doing to the way I think for myself. Brain Hygiene is where those two questions occasionally meet. This journal is where I think out loud. The retreats are where some of these ideas are explored away from screens, in nature, with space to notice what matters.

Four threads — in the journal and in the retreats

  • AttentionWhat AI is doing to our focus — and what helps us recover the capacity to stay with a thought.
  • Rest & RecoveryWhy cognitively demanding work depletes us — and what genuine recovery looks like.
  • Purpose & DirectionStaying anchored to what matters when tools, information and expectations keep accelerating.
  • Thinking TogetherHow attention, hierarchy, environment and meeting design shape our capacity to reason with other people.
