Spending time with my dogs is another huge primary food for me, and taking them on walks outside is one of the most consistent primary foods I engage in. I especially like to use this as a "bookend" after dinner to prevent me from reaching for leftovers after I'm already full.
Breathing in the fresh air immediately calms my breath and reminds me that we're all connected in this world. I love chatting with my neighbourhood friends along the way or listening to podcasts so this taps into a ton of primary foods: dogs, nature, exercise, socialising, and alone time!
