Episode 2– The Power of Connection: Community, Longevity, and a Very Unlikely Friendship in the Amazon
Runtime: 14 mins 13 secs
In this episode Helen explores how community shapes health – in humans, dogs, and even wild animals. From a small Italian-American town where neighbourly connection seemed to protect hearts, to Okinawan moai friendship groups, we look at why strong social ties sit alongside food and movement as a key piece of the longevity puzzle. Helen then dives into the gut–brain axis to unpack how stress and loneliness can disturb our microbiome and mood chemicals like serotonin, GABA and dopamine – and how life with a dog, plus a good dog park chat, might help bring things back into balance. Finally, we travel to the Peruvian Amazon, where camera traps have caught an ocelot and an opossum calmly strolling together at night, hinting at a surprising cross-species partnership and reminding us how much of social life in nature we still have to discover.
