5 Longevity Hacks That Start With How You Walk—Based on Our Biological Blueprint

The Next Big Idea Club published a Book Bite on May 22, 2026 featuring five key insights from Walk by Dr. Milica McDowell and Dr. Courtney Conley, framing walking not as optional exercise but as a physiological necessity as fundamental to human health as breathing and sleep. The piece covers the evolutionary case for daily movement, the outsized role of foot and toe strength in preventing falls and compensatory injuries, and debunks the 10,000-step myth, tracing it back to a 1960s Japanese pedometer marketing campaign rather than any scientific standard. It closes with a call to rethink modern footwear, arguing that tapered toe boxes and hyper-cushioned soles undermine the intrinsic foot strength the body was built to develop on its own.

Next Big Idea Club books are selected by Susan Cain, Malcolm Gladwell, Adam Grant, and Daniel Pink, whom Griscom called co-founders of NBIC.
