This episode is brought to you by Rupa Health, Athletic Greens, Joovv, and BiOptimizers. We can’t avoid getting older, but we can reduce biological aging—the internal process that creates all the symptoms of the disease we’ve come to call aging. That means we can be one age chronologically, and another internally. I’m happy to use myself as an example of what we can do to our biology when we take out negative inputs and embrace positive ones: I’m 63 years old but my biological age is 43. We are living in a pivotal time for reframing the intersection of age and health. My passion for this topic combined with the incredible tools I’ve discovered led me to write my new book, Young Forever, so that I could share this life-changing information with others.  Today on the podcast, I’m so excited to sit down with my friend and business partner Dhru Purohit to talk about some of the key highlights from my research on longevity. Dhru and I dive into the best way to determine your biological age so that you can begin your own journey of aging backward with measurable data. Functional Medicine provides us with the perfect framework to prevent and heal dis-ease, with the exciting side effect of reduced aging.  This episode is brought to you by Rupa Health, Athletic Greens, Joovv, and BiOptimizers.
