We Are Not Alone Inside Ourselves

The human body is not a sterile machine. It is an ecosystem.

In this episode, we explore an idea that is quietly transforming how we think about health, immunity, stress, and even human identity itself: we do not live alone. Trillions of microorganisms accompany us throughout our lives, shaping digestion, metabolism, immune function, resilience, and perhaps even aspects of mood and behavior. We talk about why microbial diversity may matter, why excessive sterility can come with biological consequences, and why bacteria are not simply enemies to eliminate.

Humans are not isolated beings. We are living systems. Or, as one sentence captures it best: “We are not alone inside ourselves.”
