Listener. You can learn a lot about a person (and by your surroundings in general) just by listening and observing, and it means I don't have to expend energy on direct interaction.
Hiking. Especially if there's edible stuff along the trails. Wild blackberries give me nostalgia of simpler times running around fields catching dragon flies.
I have always loved long walks at night or in nature for the head spaces it places me in. I simply cannot do repetitive high impact for the purpose of exercise these days because my knees aren't what they used to be. Isometrics are bomb.
Hard Copy. I think this one has appeared in a different thread (or maybe this one...not important ). I enjoy the simplicity of holding a physical book and turning the pages...and the book will be there for reading long after the Kindle's batteries have died.
Firefox. I don't mind Edge, but for a second browser Firefox has always been nicer - and I've never liked Chrome since its early days when it was damned difficult to uninstall when you needed to.
