Body, Brain & Beyond 100

Start with the mismatch between the body evolution gave you and modern life. Daniel Lieberman's evolutionary biology shows that chronic disease is not inevitable but comes from a lifestyle that does not fit our bodies, and this sets the stage for everything ahead.

Bodies evolved for walking, squatting and carrying now spend most of the day in chairs. Kelly Starrett turns that mismatch into ten daily movement habits for joints, mobility and posture, so your body stays capable and pain-free as you age.

With daily movement keeping your body capable, turn to the brain. Daniel Levitin explains how the aging brain gains real strengths and how curiosity, purpose, social ties and physical activity keep your mind sharp for decades.

Go deeper on brain protection with Dale Bredesen's protocol, which he presents as the only clinically tested lifestyle program shown to reverse early cognitive decline. Building on Levitin's foundations, it gives you a precise, personalized toolkit for preventing Alzheimer's.

After protecting the brain, rethink stress itself as a tool for longevity. Sharon Bergquist explains hormesis (the science of helpful stress) and shows how controlled cold, heat, fasting and exercise trigger cellular repair pathways that slow aging at the molecular level.

Measured physical stress builds resilience, but long-lived Okinawans also point to a calm, purposeful daily life. Ikigai shows how purpose, community and a reason to get up each morning support a long life, the human side of everything in this path.

With purpose and daily habits in place, finally look ahead. Sergey Young maps the near-term breakthroughs in AI diagnostics, regenerative medicine and genetic engineering that he expects within your lifetime, helping you understand what is coming and how to benefit from it.
