This episode dives into the nature vs. nurture debate, exploring why the Human Genome Project proved there's no single gene for speed or disease, and why 99.1% of our DNA is identical. We break down how genes like ACTN3 can give elite athletes a head start in muscle repair and VO2 max, but never guarantee greatness. Through epigenetics, we reveal how your lifestyle and environment are the real switches, using Spencer's own journey from alcohol abuse to elite marathon runner as proof. The bottom line: for the average person, consistency beats genetics every time. Your DNA only becomes the deciding factor at the very top. Who you choose to be matters more than what you were born with. Better Help 👉 Join Spencer in Saying It Louder with 10% off Betterhelp Therapy.
