I've been going to the gym for the past year after exclusively running in solitude. I am still introverted at the gym .. it's sort of my time. But I do appreciate overhearing the conversations which occur.
It's been nice to hear 60-something retirees chat about their health, quitting alcohol, sorting out the pickleball schedule, and sometimes politics (although honestly much more rare relative to the others listed)
I love the community some folks create in the gym.
