Dr. Zach Bush's work provides insights into human health and longevity. He is one of the few triple board-certified physicians in the country with an expertise in internal medicine, endocrinology and metabolism and palliative care. He joins Sophia on "Work In Progress" to talk about how he got into his field, our microbiomes, the benefits of being in nature, why everyone should try to eat fruit off of the vine, and so much more.
