Dr. Courtney Conley: Dementia, 4,000 Steps, Big Toe & The 6th Vital Sign | TUH #274

About this video

Brecka interviews foot specialist Dr Courtney Conley, who argues walking should be treated as a physiological necessity alongside breathing and sleeping. Conley links foot strength, toe function and gait — which she calls a vital sign — to fall risk, longevity and dementia risk, and criticises ill-fitting footwear that ignores foot anatomy.

Key takeaways

• Conley claims walking is what defines humans as bipeds and should be a daily physiological necessity
• She argues foot strength and mechanics are inherently connected to longevity through fall risk in older people
• Conley presents gait and foot function as an under-assessed vital sign
• Both speakers frame longevity science as largely a return to basics such as walking
